309S Stainless Steel Coil Characteristics:
Alloy 309S (UNS S30908) stainless steel coil is austenitic chromium-nickel stainless steel that provides excellent corrosion resistance and heat resistance for many important applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.
309S stainless steel coils have good weldability and can be used in the as-welded condition in construction, fabrication, and manufacturing applications. It has good resistance to pitting, crevice corrosion and stress corrosion cracking. 309S is used in many high temperature applications where the presence of Mo and Si make it resistant to sulfide stress cracking.
