Hastelloy Alloy C-22--a New and Versatile Material for the Chemical Process

Hastelloy alloy C-22 is designed based on a critical balance of chromium, molybdenum and tungsten contents. Such a balance provides unique corrosion resistance in the Ni--Cr--Mo system to oxidizing acids, localized corrosion and non-oxidising acids. Alloy C-22 also possesses thermal stability equiva...

Description
Summary:Hastelloy alloy C-22 is designed based on a critical balance of chromium, molybdenum and tungsten contents. Such a balance provides unique corrosion resistance in the Ni--Cr--Mo system to oxidizing acids, localized corrosion and non-oxidising acids. Alloy C-22 also possesses thermal stability equivalent to Hastelloy alloy C-4 in high heat input welding procedures. Applications of Hastelloy alloy C-22 demonstrate its ability to solve difficult plant corrosion problems in services where other high performance alloys have failed. 7 ref.--AA
