Vision Alloys is a leading SS 310 fastener manufacturer and a reputed stainless steel 310 nut bolt supplier in India. We offer a diverse selection of 310 stainless steel fasteners, such as nuts, bolts, washers, screws, and studs, all crafted for high-strength use in different industries. Our SS 310S fasteners are well-known for their excellent corrosion resistance, durability, and exceptional strength at high temperatures. Manufactured according to international quality standards, these products are refined for applications in heat treatment, furnace components, petrochemical, and power generation industries.
SS 310 and 310S fasteners are widely used stainless steel components due to their outstanding mechanical and heat-resistant properties. The 310 stainless steel bolts, nuts, and washers are made from an austenitic stainless steel alloy with 25% chromium and 20% nickel. This makes them much more resistant to oxidation and scaling at high temperatures. The 310S grade is a low-carbon version of 310. It makes it easier to weld and reduces the formation of carbides, which makes it perfect for use in cold and hot environments.
We produce our 310 stainless steel nuts and bolts using top-notch raw materials, guaranteeing excellent performance even in tough conditions. The composition includes chromium, nickel, carbon, manganese, silicon, phosphorus, and carbon. These elements make the fasteners highly resistant to oxidation, sulfidation, and thermal fatigue. These features make them ideal for high-temperature industrial settings and corrosive environments, guaranteeing lasting durability and reliability.
We manufacture and supply SS 310 fasteners in compliance with various international standards, including ASTM A193, ASTM A194, ASTM A320, ASME SA193, ASME SA194, and DIN specifications such as DIN 933, DIN 931, and DIN 934. We provide fasteners and nut bolts in grades like 310, 310S, and 310H, customized to meet wide industrial needs while ensuring superb strength and resistance to high-temperature oxidation.
Our stainless steel 310 bolts, nuts, and screws are available in standard and custom sizes, ranging from M3 to M64 or 3/6” to 2” in diameter, with lengths up to 500 mm. We can also create custom dimensions designed to what our clients require to be efforts our products fit a variety of industrial requirements.
