SS 439 Stainless Steel Sheet

439 is a higher grade version of 409L which contains more than 17% Cr. The higher chromium content provides an increased level of corrosion/oxidation resistance in various oxidizing environments from fresh water to boiling acids. The stabilization of carbon and nitrogen with titanium exhibits good resistance to inter-granular corrosion. This grade is approximately equal to that of austenitic grade AISI 304 in terms of resistance to general and pitting corrosion and this grade replaces 430 when better performances in ductility, formability, inter-granular corrosion are required in the as-welded condition. 439 is a good choice for the manufacture of automotive exhaust systems when application temperatures are too high for 409L.
