One of Chennai, India’s leading producers and distributors of stainless steel goods is Vinit Stainless. Known for delivering high-quality industrial solutions, we specialize in offering Stainless Steel 309/309S Stud Bolts designed for superior performance in high-temperature and corrosive environments. These stud bolts are perfect for use in petrochemical, chemical processing, and oil and gas industries because of their exceptional corrosion resistance, heat resistance, and durability. Vinit Stainless is committed to customer satisfaction, prompt delivery, and precision manufacturing to make sure our fasteners fulfill the highest performance requirements and industry standards.
An austenitic stainless steel alloy comprising roughly 24% chromium and 14% nickel is used to make stainless steel 309/309S Stud Bolts. This alloy offers remarkable resistance to oxidation and corrosion at high temperatures. These bolts have an elongation at break of 40–50%, a tensile strength of up to 860 MPa, and a yield strength of up to 350 MPa. The low-carbon version of SS 309, SS 309S, has better weldability. For high-temperature structural and mechanical applications, both grades are extremely dependable due to their exceptional resistance to carburization, thermal fatigue, and scaling.
