Based in Chennai, India, Vinit Stainless is a well-known producer and supplier of high-end stainless steel products designed for a range of industrial uses. Because of their outstanding strength, durability, and resistance to corrosion, our stainless steel 317L bolts stand out among our core products and are perfect for use in demanding and highly corrosive environments. Because these bolts are made of premium materials, they will function consistently even in the most demanding operating environments. In order to meet and surpass the expectations of our customers in India and other international markets, we at Vinit Stainless are dedicated to upholding the highest standards of product quality and customer service.
With a low carbon content (≤ 0.03%) that improves weldability and reduces carbide precipitation, stainless steel 317L bolts (UNS S31703) are made up of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. Particularly in acidic and high-chloride environments, these bolts show exceptional resistance to pitting and crevice corrosion. High tensile strength, outstanding ductility, and exceptional creep and stress-rupture resistance at high temperatures are some of their mechanical characteristics. They provide exceptional oxidation resistance, mechanical integrity, and structural stability under harsh conditions, making them a dependable option for crucial industrial applications.
