ALLOYS

Corrosion-resistant alloys (CRA) are a distinct category of metals and specialty alloys including Titanium, Zirconium, Tantalum, Hastelloy^®, high nickel alloys, as well as the duplex and super stainless steels.

Process equipment properly fabricated from these materials can handle extremely corrosive applications. Reducing or oxidizing environments, with or without chlorides, and temperatures up to 1200ºF, are all possible with these remarkable materials of construction. In addition to high resistance to uniform corrosion attack, CRAs can be very resilient to pitting, crevice and stress corrosion.

When compared with lower cost, shorter life materials like graphite or glass, the long-term cost advantages such as additional years of service and reduced cost of maintenance make the CRAs the more economical choice.

Titanium Considered the workhorse of the reactive metals, more pounds of Titanium are used for corrosion resistance than all the other reactive metals combined. It is readily available with reasonable pricing. Find out more...

Zirconium More corrosive-resistant than Titanium, Zirconium is mostly used for highly reducing environments. Its corrosive resistance in Hydrochloric acid rivals that of Tantalum. Find out more...

Tantalum The most corrosion-resistant metal in common use today. It is inert to practically all organic and inorganic compounds. Tantalum's corrosion resistance is very similar to glass. It is acid proof up to around 300ºF. Find out more...

Hastelloy® A registered trademark of Haynes International Inc., the Hastelloy family of high nickel alloys has been proven around the world in a wide range of industries and applications. Find out more...

Duplex Stainless Steel A mixed microstructure of austenite and ferrite with properties of both, Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion. Find out more...
