Vision Alloys is a leading SS 317 fastener manufacturer and a reputed stainless steel 317L nut bolt supplier in India. We offer a diverse selection of 317 stainless steel fasteners, such as nuts, bolts, washers, screws, and studs, all crafted for high-strength use in different industries. Our SS 317L fasteners are recognized for their exceptional corrosion resistance, durability, and high tensile strength. They comply with international quality standards and are top-notch for marine, chemical processing, and high-temperature applications.
SS 317 and 317L fasteners are popular because they offer excellent corrosion resistance, particularly when it comes to acids and chlorides. The 317 stainless steel bolts, nuts, and washers are made from an austenitic stainless steel alloy containing 19% chromium, 13% nickel, and 3–4% molybdenum. This chemical composition helps reduce the chances of pitting in the steel. The 317L grade is a low-carbon type that provides improved weldability and minimizes carbide precipitation, which makes it perfect for high-stress and corrosive settings.
Our 317 stainless steel nuts and bolts are crafted from high-quality raw materials to ensure reliability in critical applications. This composition features chromium, nickel, molybdenum, carbon, manganese, silicon, and phosphorus, all of which contribute to excellent resistance against rust, pitting, and stress corrosion cracking. These properties make them suitable for both mild and aggressive industrial environments, guaranteeing long-lasting performance.
We manufacture and supply SS 317 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 offer grades like 317, 317L, and 317H, which provide excellent strength and corrosion resistance for many types of uses.
We offer 317 stainless steel bolts, nuts, and screws in both standard and custom sizes. You can choose from schedules ranging from SCH 10 to SCH 80, with dimensions available from M6 to M42 or 1/4” to 1-1/2” in diameter. We can create fasteners in custom lengths and widths, making sure they fit perfectly for your specific industry requirements.
At Vision Alloys, we prioritize safe packaging using wooden boxes, plastic wraps, and bubble wraps to prevent damage during transit. We provide fast delivery for clients both at home and abroad, making sure that urgent project needs are fulfilled on time.
