Harsh Metalloys, a reputable manufacturer and supplier located in Mumbai, India, specializes in high-performance Stainless Steel 301 Nuts. These nuts are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. SS 301 is an austenitic stainless steel that gains impressive tensile strength through cold working, making it perfect for fasteners in tough environments. Manufactured to meet international standards like ASTM A194 and DIN specifications, Harsh Metalloys offers Stainless Steel 301 Nuts in a variety of sizes, thread types, and finishes, catering to the rigorous demands of industries such as automotive, aerospace, construction, and general engineering.
When it comes to the composition and mechanical properties of Stainless Steel 301 Nuts, they typically consist of Chromium (16–18%), Nickel (6–8%), Carbon (≤0.15%), Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). These nuts boast impressive mechanical properties, achieving tensile strength up to 930 MPa and yield strength around 520 MPa when cold worked. They also show good corrosion resistance, high hardness, and excellent fatigue strength. While SS 301 is non-magnetic in its annealed state, it becomes magnetic when cold worked. These characteristics make SS 301 nuts ideal for applications that require secure fastening in high-stress and corrosive environments.
