Harsh Metalloys, located in Mumbai, India, stands out as a leading manufacturer and supplier of high-quality Stainless Steel 301 Fasteners. Renowned for their impressive strength and outstanding resistance to corrosion, 301 fasteners are perfect for applications that demand both durability and flexibility. They come in various forms, including bolts, nuts, screws, washers, and studs, all crafted to meet ASTM and DIN standards. With meticulous manufacturing processes and rigorous quality control, Harsh Metalloys guarantees exceptional performance and reliability. These fasteners find extensive use in industries such as automotive, aerospace, railway, construction, and marine, where mechanical strength and wear resistance are essential.
Stainless Steel 301 Fasteners are made up of Chromium (16–18%), Nickel (6–8%), and Carbon (≤0.15%), along with Manganese (≤2%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). They boast impressive mechanical strength, achieving tensile strength up to 930 MPa and yield strength around 520 MPa, depending on the temper. Additionally, they show good elongation and hardness, making them ideal for cold working. This composition provides these fasteners with excellent resistance to atmospheric corrosion, moderate oxidation, and wear, while ensuring they maintain formability and mechanical integrity even in high-stress situations.
