Vinit Stainless, a reputable manufacturer and supplier of stainless steel 330 nuts with headquarters in Chennai, India, offers high-performance fastening solutions for corrosive and extremely hot conditions. Our SS 330 nuts are made from premium austenitic nickel-chromium alloy steel and are renowned for their strength, resilience to oxidation, and longevity. These nuts are produced in accordance with international standards and specifications, making them perfect for uses involving thermal cycling and extended heat exposure. Vinit Stainless provides heat treatment, petrochemical, power generation and furnace equipment manufacturers in both domestic and foreign markets with precisely crafted 330 nuts in a range of sizes, guaranteeing dependable performance.
About 35–37% nickel and 17–20% chromium make up Stainless Steel 330 Nuts, with trace amounts of silicon, manganese, and iron. At temperatures as high as 1150°C, this composition offers exceptional resistance to oxidation, carburisation, and scaling. SS 330 nuts have outstanding creep and stress rupture characteristics, as well as tensile strength between 550 and 750 MPa and yield strength of about 205 MPa. In both oxidising and reducing conditions, the alloy retains its strength and ductility. These nuts are perfect for high-temperature structural and fastening applications because they have good weldability and resistance to thermal fatigue.

Many industries that work in corrosive environments and with high temperatures use stainless steel 330 nuts. Applications include petrochemical processing facilities, exhaust systems, combustion chambers, industrial furnaces, and heat treatment equipment. They are also necessary for parts of thermal reactors, power plants, and incinerators where resistance to thermal cycling and oxidation is critical. SS 330 nuts preserve mechanical joints and structural integrity when subjected to constant use at high temperatures. They are perfect for fastening parts in steel plants, glass factories, and chemical processing settings where traditional fasteners would fail because of their resistance to carburisation and scaling.
