Harsh Metalloys, a trusted manufacturer and supplier located in Mumbai, India, specializes in precision-engineered Stainless Steel 410 Nuts. These nuts are celebrated for their impressive strength, hardness, and resistance to wear. SS 410 is a type of martensitic stainless steel that can be hardened through heat treatment, making it perfect for fastening applications that face mechanical stress and mild corrosion. Our 410 nuts are crafted to comply with ASTM and international quality standards, and they come in a range of sizes and thread types. These fasteners are ideal for use in industrial machinery, automotive systems, and equipment that operates under high-load or abrasive conditions.
Stainless Steel 410 Nuts are mainly made up of 11.5–13.5% Chromium and up to 0.15% Carbon, which creates a martensitic structure that can be heat-treated to enhance hardness and strength. These nuts typically boast a tensile strength between 500–700 MPa and can reach a hardness of up to 40 HRC. While they may not be as corrosion-resistant as austenitic grades, SS 410 still offers decent oxidation resistance and durability in mildly corrosive or dry environments. Additionally, this material is known for its good machinability and excellent resistance to wear and galling, making it a great choice for high-performance mechanical fastening.
