Vision Alloys is a leading SS 316 fastener manufacturer and a reputed stainless steel 316 nut bolt supplier in India. We offer a diverse selection of 316 stainless steel fasteners, such as nuts, bolts, washers, screws, and studs, all crafted for high-strength use in different industries. We use SS 316L fasteners in various industries like marine, chemical processing, food processing, and pharmaceuticals because they resist pitting, crevice corrosion, and tough environments highly effectively.
SS 316 and 316L fasteners are among the most corrosion-resistant stainless steel components, ideal for applications exposed to moisture, chemicals, and extreme conditions. The bolts, nuts, and washers are crafted from 316 stainless steel, which is an austenitic alloy containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. This composition makes them resistant to corrosion, particularly in areas with high chloride stages. The 316L grade is a low-carbon version of 316, offering better weldability and resistance to sensitization, making it suitable for high-temperature and cryogenic applications.
We make our 316 stainless steel nuts and bolts from top-notch raw materials, guaranteeing they perform impressively even in tough conditions over time. This blend contains chromium, nickel, molybdenum, carbon, manganese, silicon, and phosphorus, all of which help improve resistance to rust, oxidation, and stress corrosion cracking. SS 316 fasteners are a superior choice for offshore structures, medical equipment, heat exchangers, and industrial piping systems due to their unique properties.
We manufacture and supply Stainless Steel 316 fasteners in compliance with international standards such as ASTM A193, ASTM A194, ASTM A320, ASME SA193, ASME SA194, and DIN specifications including DIN 933, DIN 931, and DIN 934. Our fasteners are available in multiple grades, including 316, 316L, and 316H, ensuring they meet a variety of industrial requirements while providing exceptional strength, durability, and resistance to extreme conditions.
Our 316 stainless steel 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 also offer customized dimensions to meet specific client requirements, ensuring compatibility with diverse industrial applications.
