The Importance of Investing in High Performance Alloys

Typical steels or more common types of metal usually don’t hold up when put into the vicinity of high temperatures starting with turbines up to the corrosive and erosive effects of water and chemicals to the extent of using steels for large mechanical systems which have much heavier loads placed on them than both chemical and water applications. Superalloys, duplex alloys, cobalt alloys and heat resistant steels fill the gap of what traditional alloys have failed at.

With the proper alloy, the following characteristics are maintained:

• Resistance against extreme heat and thermal cycling
• Resistance against corrosion, abrasions, and erosions
• Strength and toughness maintained while applying mechanical forces
• Will operate and perform reliably over the long term with little to no corrosion and a fictitious lifespan

At Austin Alloy Cast, we have a complete line of materials; Carbon Steels, Stainless Steels, Alloy Steels, Duplex and Super Duplex grades, Tool Steels, Nickel Alloys, Cobalt Alloys, Monel and Heat Resisting Steels allowing you the freedom to select a material that’s best suited for your application.

Superalloys; Strength & Stability Under Extreme Heat

For applications involving high temperatures and thermal stresses such as turbines, furnace parts, power plant components and aerospace hardware nickel based superalloys and other heat resistant alloys are the materials of choice.

These alloys:

• Maintain strength at elevated temperatures
• Resist creep and deformation under sustained heat
• Offer oxidation and thermal fatigue resistance

At Austin Alloy Cast, our foundry is fully equipped to cast these superalloys in air-melt condition via the lost wax investment casting process, ensuring fine surface finish, dimensional accuracy, and minimal defects.

Once cast, components are subjected to strict heat treatment, inspection, and quality control guaranteeing performance even in the most demanding thermal environments.

In fact, Nickel based alloys like Inconel 625 are regularly poured at our foundry. We have the capabilities to execute large order in such exotic materials.

Duplex & Super Duplex Steels; Balancing Strength with Corrosion Resistance

For industries like marine, offshore, chemical processing, and petrochemical components often face harsh corrosion, saltwater exposure, acidic media, or chloride rich environments. Simple stainless steel may not suffice here.

Duplex and Super Duplex steels are alloys made with Austenitic and Ferritic phases, and represent the perfect marriage of strength and corrosion resistance due to their:

• High tension and toughness
• Resistance to Pitting, Crevice and Stress Corrosion
• Reliability under cyclic loads and corrosive environments

We’re able to use these alloys in pump housings, valve bodies, subsea components, offshore equipment and chemical processing hardware.

We regularly cast components of duplex grades at our facility, closely monitoring the microstructure to ensure compliance with stringent industry regulations.

Tool and Cobalt Alloys; Designed for Wear, Erosion, and Hardness.

Wherever wear resistance, galling resistance, or sustaining hardness is critical due to an application’s requirement for a combination of high stress TEMPERATURE conditions, Cobalt Based Alloys are outstanding choices.

Cobalt Based Alloys, along with their excellent wear resistance, are also ideal for the following applications:

• Valve seats, trims and cores
• Pump components including sleeves, bushings, etc. subject to significant wear
• Die, Tool, and Wear Plate Applications for Hot Working Application
• Any component that will be subjected to abrasive/erosive MEDIA.

Cobalt Base Alloys may prove difficult to machine or forge; therefore, investment casting would be a preferred method. At Austin Alloy Cast, we utilize our ability to cast cobalt based alloys to cast complex geometries and intricate parts with a minimum amount of finishing and consistent mechanical properties.

Heat resistant steels/alloys Dealing with thermal cycles and environmental strain

Many industries use heat resistant materials via periodic thermal cycles, oxidising atmospheres, or extended periods of exposing to HIGH TEMPERATURES. For those conditions, heat resistant steels or Specialty Alloy Steels provide you with the durability you need.

These materials withstand the following:

• Scaling and Oxidation
• Thermal fatigue and distortion
• Loss of Mechanical Strength over multiple cycles.

Through precise control in melting, casting, and post casting heat treatment, Austin Alloy Cast ensures that heat resistant steel castings meet design specifications and withstand long term exposure to thermal stress.

Metallurgy, Process Control, and Quality are Important

High performance castings require more than just choosing a good alloy. At Austin Alloy Cast we focus on:

• Accurate chemistry and composition of the melt,
• Proper handling of the wax pattern, including controlled shell building,
• Controlled temperature and time for pouring and solidification,
• Proven heat treatment cycles that meet the requirements of each alloy,
• Thorough inspections and tests, including radiographic, dye penetrant, magnetic particle, ultrasonic, microstructure examination and dimensional measuring.

This structured process ensures that the castings supplied to customers are free from any defects, correctly sized, and possess consistent mechanical and chemical characteristics in extreme service environments.

Conclusion

In the current competitive manufacturing environment, design engineers and procurement groups feel pressure to lower costs, enhance product reliability, and shorten production cycles… without sacrificing quality. At Austin Alloy Cast, a leading investment casting manufacturer whose primary focus is stainless steel casting, we regularly partner with customers to achieve these goals by replacing the conventional welded assembly process with one singular, Robust, cast component.

This case study illustrates how our transformation not only simplified our customer’s manufacturing, but also decreased their cost by nearly 60%, improved product performance, and increased efficiency overall.

Background: The Challenge of a Welded Assembly

Austin Alloy Cast was approached by their client, a well-known Valve manufacturer, because of ongoing issues with one of their critical components a welded stainless steel housing assembly made of multiple components that were assembled together using complicated welding processes.

While the welded design seemed reasonable at first, it started to deteriorate rapidly with significant disadvantages related to:

• Costly fabrication with multiple subcomponents, welding labour and the potential of rework. In most developed countries, there is shortage of skilled Labours.
• Difficulties in distortion and alignment as a result of weld heat input.
• Varied mechanical properties in and around the weld areas.
• Long manufacturing cycle times due to post weld machining, inspection and testing.
• Poor surface finish that required expedited machining to meet functional needs.

The customer wanted to keep the same functional design while improving strength and consistency at a lower cost and Austin Alloy Cast had the right answer with investment casting.

Solution: Replace ‘Welded Assemblies’ with a Singular Investment Cast Component.

Following a thorough feasibility study the engineering team recommended changing the welded housing assembly into a one piece, investment cast component made of a WCB/CF8M material.

The advantages of this solution included:

1. Design Simplification:

The component structure can now be created as one, nearly net shape cast product without any welded joints or assembly operations. Additionally, complex internal passageways and contours that need to be welded can now be produced directly during the investment casting process, as investment castings possess an inherent ability to reproduce complex geometries.

2. Better Mechanical Properties:

Welded parts often present heat affected zones (HAZ) with different microstructures and residual stresses, but investment cast parts are uniform and have isotropic mechanical properties throughout. The investment casting process offers better fatigue life, greater load capability, and superior resistance to corrosion and cracking.

3. Better Surface Finish and Dimensional Tolerance:

It follows that investment castings will provide a quality surface finish and tight tolerances. This provided significant machining time savings, as the part will have near net-shape finish.

4. Lost-wax process offers great repeatability:

Overall production lead time has been significantly reduced. The requirement for numerous welding, alignment, inspection, and subsequent heat treatment steps have all but disappeared, allowing for a much quicker and consistent production flow.

5. Economic Benefit:

Perhaps most impressive was the cost reduction of nearly 60% of the prior welded assembly. This was realized through material optimization, followed by the absence of multiple manufacturing steps, as well as reduced manpower and inspection time.

How Austin Alloy Cast Made It Happen:

At Austin Alloy Cast, any undertaking begins with a structured, engineering based process.

1. Design for Casting (DFC):

We worked closely with the customer’s design engineers in order to design the part geometry for casting. The fillet radii, draft angles, and wall thickness were optimized for proper metal flow and sound castings.

2. Tooling and Wax Pattern Development:

Investment casting tooling was developed to accurately match the redesigned model. Wax patterns were manufactured and assembled into trees, minimizing dimensional instability.

3. Shell Building and Pouring:

Utilizing a controlled ceramic shell process, a durable mold was created. Molten stainless steel was poured with strict metallurgical controls to achieve a uniform grain structure and density.

4. Heat Treatment and Finishing Processes:

To improve mechanical properties and corrosion resistance, the castings underwent solution annealing. Operational CNC machining was kept to a minimum to achieve final tolerances. Surface finishing, along with non destructive testing (NDT) assessed the parts for integrity.

5. Inspection and Validation Processes:

To ensure that each part would fit properly and was dimensionally correct, it was stamped upon validation using a CMM Coordinate Measuring Machine. NDT methods, including dye penetrant and radiography, helped confirm the absence of internal defects and surface defects.

Results: Tangible Gains in Every Metric

The switch from a multi piece welded assembly to a single stainless steel investment cast part resulted in meaningful and substantial improvements in all factors related to both production and performance. The most significant benefit was the significant cost savings a reduction of around 60% all due to not having to perform the several steps of fabrication: cutting, aligning, welding, grinding, and heat treatment. The part could be cast as a single component, so a highly skilled welder, a jig, fixture, and multiple inspections were not required; thus, the labor costs were much lower and the overhead directly associated with these inspections dropped to zero.

In addition, the lead time for manufacturing was less for the same reason. The investment casting process created a predictable and repeatable flow of work that eliminated the need to plan for countless fabrication processes or wait on inspection criteria. Instead, Austin Alloy Cast was able to deliver finished castings in short lead times, increasing customer turns and supply chain efficiency.

From a technical perspective, the new investment cast design exhibited better mechanical integrity and reliability. The previous welded joints were typical weak points that sometimes formed microcracking or stress concentrations with cyclic loads and thermal shifts. The investment cast component had consistent mechanical properties and performance throughout the entire component, with no weld weak points due to cracking, hardness variations, or strength.

The resulting part had better tensile and fatigue resistance and improved corrosion resistance, as well as less dimensional changes during operation. Additionally, the investment cast surface finish and dimensions from an assembly standpoint were improved over welded assembly. Also, the investment cast parts near net shape quality minimizes fabrication and tooling time, and material savings enable consistent and predictable performance/consistency.

In conclusion

This case study has shown how Austin Alloy Cast a trusted investment casting manufacturer facilitates the transition from complex welded assemblies to cost effective high strength stainless steel castings.

By leveraging our knowledge in investment casting and stainless steel castings we help industries achieve optimized designs, reduced costs, better reliability, and faster turnaround.
