Based in Chennai, India, Vinit Stainless is a top producer and supplier of high-end stainless steel goods designed for demanding industrial uses. The company, which is well-known for its dedication to accuracy and quality, specializes in manufacturing high-performance parts like stainless steel 446 stud bolts. Because of their exceptional resistance to heat, corrosion, and oxidation, these fasteners are designed to be used in harsh environments. Vinit Stainless produces goods that satisfy global standards through advanced manufacturing techniques and stringent quality control. Because of their unparalleled strength and durability, their 446 stud bolts are widely trusted by industries like petrochemical, power generation, and furnace manufacturing.
The high-chromium ferritic stainless steel alloy used to make stainless steel 446 Stud Bolts normally contains 23–27% chromium, with trace amounts of silicon, manganese, and molybdenum added for performance. Up to 1100°C, the material retains its structural stability and provides exceptional resistance to oxidation at high temperatures. It has moderate elongation, a yield strength of about 275 MPa, and a tensile strength of about 485 MPa. Although it can be work-hardened, heat treatment cannot harden it. Because of these characteristics, it is ideal for industrial applications involving corrosive and hot service conditions.
