Harsh Metalloys stands out as a top manufacturer and supplier of premium Stainless Steel 317 Fasteners right in Mumbai, India. Designed for exceptional durability and impressive corrosion resistance, these SS 317 fasteners are perfect for harsh chemical environments, thanks to their high molybdenum content. They come in various forms, including bolts, nuts, washers, screws, and studs, all adhering to international standards like ASTM A193/A194. These fasteners are particularly well-suited for industries such as chemical processing, pulp and paper, marine, and pharmaceuticals. With their outstanding performance in acidic and chloride-rich settings, Stainless Steel 317 fasteners guarantee long-lasting, secure, and corrosion-resistant assemblies for critical applications.
When it comes to composition and mechanical properties, Stainless Steel 317 Fasteners usually consist of 18–20% Chromium, 11–15% Nickel, and 3–4% Molybdenum, which boosts their resistance to pitting and crevice corrosion. These fasteners showcase a tensile strength between 515–750 MPa and a yield strength of about 205 MPa. In their annealed state, SS 317 is non-magnetic and retains excellent mechanical properties even in high-temperature conditions up to 870°C (1600°F). This alloy is also recognized for its good weldability, ductility, and strong resistance to chemical attacks, making it a fantastic choice for demanding fastening tasks that involve stress, pressure, and exposure to harsh chemicals.
