Aditya Stainless stands out as a trusted manufacturer and supplier of Stainless Steel 301 Fasteners right in Kolkata, India. We specialize in delivering precision-engineered fastening solutions tailored for both structural and industrial needs. SS 301 is an austenitic stainless steel celebrated for its impressive strength, remarkable ductility, and resistance to corrosion, particularly when cold-worked. These fasteners find their place in various sectors, including automotive, railway, aerospace, architecture, and industrial machinery, thanks to their excellent formability and ability to maintain strength post-fabrication. Our SS 301 fasteners come in a range of types—bolts, nuts, screws, washers, and studs—ensuring durable performance even in demanding, vibration-prone, and mildly corrosive environments.
Stainless Steel 301 Fasteners are made up of 16–18% chromium, 6–8% nickel, along with trace amounts of carbon, manganese, and silicon. When cold-worked, this alloy can reach a tensile strength of up to 930 MPa, a yield strength of around 520 MPa, and an elongation of about 40%. SS 301 is known for its good fatigue and wear resistance, along with moderate corrosion resistance in mildly oxidizing or moist conditions. Its excellent work hardening properties make it a great choice for applications that require strong yet flexible fasteners capable of enduring repeated mechanical stress and temperature fluctuations.
