Aceroinoxidable----Ferritic Stainless Steels 444 UNS S44400

 

This alloy could be a low carbon and low Nitrogen ferritic  stainless steel that contains eighteen Cr and a pair of Mo. One advantage of kind 444 over primary solid solution unsullied steels, like 304 and 316 alloys, is that the sensible immunity of the kind 444 alloy to chloride stress corrosion cracking (SCC). The alloy’s increased resistance to corrosion and crevice corrosion combined with its sensible general corrosion resistance to a large number of environments makes it a wonderful selection for a good vary of applications like device tube, food process instrumentation, plight tanks, and automotive exhaust.
