Based in Chennai, India, Vinit Stainless is a leading manufacturer and supplier of stainless steel products. It is well known for its dedication to providing high-quality, performance-driven materials to satisfy a range of industrial demands. Stainless Steel 446 Bolts are one of our specialty products; they are designed to withstand high temperatures and corrosive conditions. These bolts, which are made for demanding applications, demonstrate our commitment to robustness, dependability, and durability. Vinit Stainless is a trustworthy partner for industries in India and abroad because we deliver precision-manufactured stainless steel solutions supported by prompt customer service and consistent product quality.
The main constituents of stainless steel 446 bolts are iron and 23–27% chromium, with trace amounts of silicon and molybdenum added to improve resistance to oxidation and scaling. This grade of ferritic stainless steel is renowned for its exceptional resistance to corrosion, particularly at high temperatures. High-temperature stability, magnetic qualities, and mechanical strength are all demonstrated by SS 446 bolts. In harsh environments, they retain structural integrity due to their strong weldability and machinability. These bolts are appropriate for high-stress industrial settings and thermal cycling because of the material’s oxidation resistance, which reaches even above 1100°C.
