Nickel-base steel alloys

While investment casting can be used to pour almost any alloy, our most popular alloys are in the nickel family. Nickel-based alloys consist primarily of nickel, chromium, and molybdenum, and are one of the most widely used investment casting materials. The most popular is CW-2M.

Great precision and skill are needed to create a nickel-based alloy. At CIREX, we create superior alloys by paying careful attention to the composition of the material we melt. Our casting process creates castings with a high metallurgical purity and excellent weldability.

Which Industries Use Nickel-Based Alloys?

Any industry can use nickel-based alloys, but the majority of our customers who use them are looking for the best corrosion resistance in oxidising environments. Additional elements like molybdenum and chromium are added to create an alloy that is arguably one the world’s toughest.

When should you use a nickel-based alloy? If 300 series stainless steels are not good enough, then nickel-based alloys are an excellent alternative for components used in the chemical and process industries. Furthermore, meter bodies used in chlorine and acid services utilise CW-2M for its excellent mechanical and physical properties.

High-Performance Alloys

Nickel-based alloys are high-performance alloys. They are highly resistant to corrosion and oxidation and are harder, stronger and more corrosion resistant than other metals at higher temperatures. This makes them ideal for welding applications. Some alloys lose corrosion resistance at higher temperatures, but nickel-based alloys do not. They also have excellent ductility and are easy to fabricate.

CIREX develops and produces high quality investment castings which can be cast in virtually any steel alloy. We are committed to giving you the very best-performing part at the lowest total cost. When it comes to an investment casting, you do not need to compromise. Contact our team today to discover our capabilities manufacturer.

Did You Know?

Hastelloys are brand name nickel-based alloys invented by Haynes International in 1912. When the original patent, manufacturers could develop “generic” or off-brand “Hastelloys”. For example, our CW-2M is equivalent to Hastelloy C. So although it has a different name, CW-2M has exactly the same characteristics and performance as the original Hastelloy.
