High-quality stainless steel 309 fasteners for industrial and high-temperature applications are available from Vinit Stainless, a well-known stainless steel fastener manufacturer and supplier with headquarters in Chennai, India. These fasteners are designed to function dependably in extremely hot environments and are well-known for their remarkable resistance to heat and oxidation. Vinit Stainless uses rigorous adherence to international standards and precision manufacturing to guarantee exceptional product quality. Our SS 309 fasteners are extensively utilised in industries like heat treatment, metallurgy, petrochemicals, and power generation. Our primary values are performance and durability, and we provide fastening solutions that satisfy the most exacting engineering specifications.
The main constituents of stainless steel 309 fasteners are nickel (12–15%) and chromium (22%–24%), with up to 0.20 percent carbon. At high temperatures, this composition offers exceptional strength and resistance to oxidation. These fasteners have an elongation of roughly 40%, a yield strength of about 205 MPa, and a tensile strength of about 515 MPa. Under heat stress, their austenitic structure guarantees excellent stability and toughness. When it comes to components that are subjected to frequent cycles of heating and cooling, SS 309 fasteners are perfect for thermal environments where mechanical integrity and resistance to scaling are crucial.
