Based in Chennai, India, Vinit Stainless is a well-known producer and supplier of high-end stainless steel fasteners, such as Stainless Steel 309S Fasteners. These fasteners have outstanding oxidation and corrosion resistance and are made for high-temperature applications. Vinit Stainless produces fasteners that satisfy international standards by using sophisticated manufacturing techniques and stringent quality control. Applications for our SS 309S fasteners are common in power plants, industrial furnaces, and heat treatment. We provide fastening solutions that are exceptional in structural strength and heat resistance, all while maintaining a dedication to performance, longevity, and customer satisfaction.
Chromium (22–24%) and nickel (12–15%) make up the composition of stainless steel 309S fasteners, which have a low carbon content (maximum 0.08%) to improve weldability and lessen carbide precipitation. These fasteners have an elongation of about 40%, a yield strength of about 205 MPa, and a tensile strength of about 515 MPa. Excellent toughness at high temperatures is guaranteed by the austenitic structure. For structural and thermal applications involving high heat and moderate corrosion, SS 309S is a good choice because it combines dependable mechanical qualities with good oxidation resistance.
