Harsh Metalloys, a prominent manufacturer and supplier located in Mumbai, India, specializes in high-performance Stainless Steel 301 Bolts that are built for strength, durability, and wear resistance. Renowned for their impressive mechanical properties and moderate corrosion resistance, SS 301 bolts are perfect for tough structural and fastening tasks. These bolts are meticulously engineered to comply with international quality standards such as ASTM, DIN, and ISO. Harsh Metalloys offers SS 301 bolts in a wide range of sizes, thread types, and finishes, catering to industries like automotive, aerospace, railways, construction, and industrial machinery, where dependable performance and high strength are crucial.
Stainless Steel 301 Bolts are made up of Chromium (16–18%), Nickel (6–8%), Carbon (≤0.15%), Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). This alloy strikes a perfect balance between formability and strength, boasting excellent work-hardening capabilities. Typically, these bolts show a tensile strength of up to 930 MPa, a yield strength of around 520 MPa, an elongation of about 40%, and hardness that varies with temper. These characteristics make 301 bolts well-suited for high-stress, mechanically demanding applications, ensuring durability and stability even when subjected to vibrations and fluctuating load conditions.
