Harsh Metalloys is a well-respected manufacturer and supplier of Stainless Steel 202 Fasteners, located in Mumbai, India. SS 202 is an austenitic stainless steel that combines chromium, nickel, and manganese, providing a cost-effective alternative to the 300 series while still offering solid mechanical strength and decent corrosion resistance. Harsh Metalloys offers a wide variety of SS 202 fasteners, including bolts, nuts, screws, washers, and threaded rods, available in different sizes and specifications. These fasteners are crafted to meet international quality standards like ASTM, DIN, and ISO, making them perfect for construction, transportation, household appliances, and general engineering projects.
Stainless Steel 202 Fasteners generally consist of 17–19% chromium, 4–6% nickel, and 7.5–10% manganese, along with small amounts of carbon, nitrogen, and silicon. They boast a tensile strength of about 515 MPa, a yield strength of around 275 MPa, and an elongation of 40%. While SS 202 fasteners are non-magnetic in their annealed state, they can become slightly magnetic when cold worked. They offer excellent formability, weldability, and moderate resistance to corrosion and oxidation, making them suitable for indoor use and light outdoor applications that aren’t exposed to harsh corrosive conditions.
