Vinit Stainless is a reliable SS 314 Fasteners manufacturer and supplier in Chennai, India that specializes in providing high-performance fastening solutions for industrial and structural purposes. Our SS 314 fasteners are designed with superior heat resistance, oxidation resistance, and durable long lifespan. These fasteners are often utilized in applications where high-temperature strength is an essential requirement and have excellent performance in furnace parts, exhaust systems, and heat treating equipment. Vinit Stainless offers SS 314 fasteners in multiple forms like bolts, nuts, washers, and studs that are designed to meet international standards for mechanical strength and corrosion resistance.
SS 314 fasteners are manufactured from an austenitic stainless steel alloy with a composition of around 24–26% chromium and 19–22% nickel with the addition of silicon (about 1.5–3%) for enhanced oxidation resistance. These fasteners have a tensile strength of around 620 MPa and a yield strength of around 240 MPa. They have no loss of strength up to 1150°C. Their toughness, oxidation resistance, and creep resistance make SS 314 fasteners suitable for thermal cycling conditions and high-heat applications.
