Harsh Metalloys, a leading manufacturer and supplier located in Mumbai, India, specializes in high-quality Stainless Steel 405 Fasteners. These fasteners are perfect for applications that face moderate corrosion and high temperatures. SS 405 is a ferritic stainless steel that’s stabilized with aluminum, giving it impressive resistance to scaling and minimizing the chances of weld hardening. Our selection includes bolts, nuts, washers, screws, and studs, all crafted to meet ASTM and DIN standards for precision and performance. They’re ideal for use in heat exchangers, petrochemical equipment, automotive exhaust systems, and other thermal environments where dimensional stability and dependable fastening are crucial.
When it comes to composition and mechanical properties, Stainless Steel 405 Fasteners consist of 11.5–14.5% Chromium, low Carbon (≤ 0.08%), and 0.10–0.30% Aluminum for stabilization. These ferritic stainless fasteners provide moderate tensile strength (around 380–450 MPa), good ductility, and high oxidation resistance up to 675°C. They are excellent at resisting thermal fatigue and don’t harden much during welding. SS 405 fasteners are magnetic, non-hardenable through heat treatment, and offer good machinability. Their structural stability under heat and stress makes them a great choice for mechanical connections in high-temperature applications with light to moderate corrosion exposure.
