Alloys 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.
Calico Metal Alloys LLP carries a variety of 309/309S Stainless Steel Nuts from Carbon Steel, Stainless Steel and High Nickel Alloy -F467 NiCu 400 (Monel) and commercial 18-8/304, 316 Stainless Steel. We supply 309/309 Stainless Steel Nuts at best price..Our 304 Stainless Steel Fasteners plant is equipped with various testing facilities like Tensile Testing Machine also known as tension testing. We also conduct other tests like Hardness Test, IGC Test, Positive Material Identification Test to ensure that all the product going out of our manufacturing plant are the best in terms of quality.
