Nickel-based steel alloys

While the investment casting process can pour almost any alloy, our most popular alloys are in the nickel family. Comprising primarily nickel, chromium and molybdenum, nickel-based alloys are among the most widely used materials for investment casting. The most popular is CW2M.

Creating a nickel-based alloy requires great precision and skill. At Signicast, we pay close attention to the composition of the material we melt to ensure we create superior alloys. Our casting process produces metallurgically clean castings with excellent weldability.

Which industries use nickel-based alloys?

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

When should you use a nickel-based alloy?  If 300 series stainless steels are insufficient, nickel-based alloys are well suited to components used in the chemical and process industries. In addition, meter bodies used in chlorine and acid service applications use CW-2M for its excellent mechanical and physical properties. 

High-performance alloys

Nickel-based alloys are part of the superalloy family, also known as high-performance alloys. In addition to being highly resistant to corrosion and oxidation, these alloys are harder, stronger and remain corrosion-resistant at higher temperatures, making them an excellent option for welding applications. Some alloys lose corrosion resistance as temperature rises; nickel-based alloys do not. They also have excellent ductility and can be readily fabricated.

Signicast offers everything from 400 stainless steel to aluminium. We are committed to providing the highest-performing part at the lowest total cost. 

Did you know?

Hastelloys are branded nickel-based alloys invented by Haynes International in 1912. The original patent expired, allowing manufacturers to develop "generic" or unbranded "Hastelloys". For example, our CW-2M is equivalent to Hastelloy C. Although the name may differ, the alloy functions and performs just like the original Hastelloy.
