Harsh Metalloys is a reliable manufacturer and supplier of Stainless Steel 304 Nuts, located in Mumbai, India. SS 304 is the go-to choice for austenitic stainless steel, striking a perfect balance between corrosion resistance, strength, and cost-effectiveness. Our SS 304 nuts are meticulously engineered and produced in line with international standards like ASTM F594 and DIN 934, ensuring they perform exceptionally well in a variety of industrial and structural settings. Available in various sizes, grades, and thread types, these nuts are perfect for construction, automotive, food processing, chemical, and marine industries that demand trustworthy and durable fastening solutions.
Stainless Steel 304 Nuts are made up of 18–20% chromium and 8–10.5% nickel, along with trace amounts of carbon, manganese, and silicon. They boast a tensile strength ranging from 500–700 MPa and a yield strength of about 210 MPa, along with impressive elongation and toughness. While they are non-magnetic in their annealed state, they can become slightly magnetic after cold working. SS 304 nuts excel in resisting corrosion, oxidation, and general atmospheric conditions, making them suitable for both indoor and outdoor applications. Their outstanding strength and chemical resistance guarantee reliable performance even in the toughest environments.
