Material properties
Excellent raw material selection
444 stainless steel
Chromium-molybdenum ferritic stainless steel 444 offers excellent corrosion resistance together with outstanding formability and weldability. Type 444 is a ferritic stainless steel with low carbon and nitrogen content that offers better resistance to pitting and crevice corrosion than most ferritic stainless steels. This alloy is best suited for applications needing exceptional corrosion resistance and resistance to chloride stress corrosion cracking.
