Harsh Metalloys, located in Mumbai, India, is a trusted manufacturer and supplier of Stainless Steel 201 Bolts, celebrated for their affordable corrosion resistance and impressive mechanical strength. These bolts are crafted from a high-manganese, low-nickel alloy, providing a robust alternative to conventional stainless steels, making them perfect for general-purpose fastening in moderately corrosive settings. We adhere to international standards like ASTM and DIN to guarantee consistent quality and performance. Harsh Metalloys offers a diverse selection of sizes and types of 201 bolts, catering to industries such as construction, automotive, and manufacturing both in India and internationally.
Stainless Steel 201 Bolts are generally composed of Chromium (16–18%), Nickel (3.5–5.5%), Manganese (5.5–7.5%), Carbon (≤0.15%), Silicon (≤1%), Phosphorus (≤0.045%), and Sulfur (≤0.03%). This alloy boasts good tensile strength, typically around 620 MPa, and a yield strength of about 310 MPa, with an elongation of roughly 30–40%. While it has a lower nickel content, 201 stainless steel still offers decent corrosion resistance and mechanical properties, making it suitable for light to moderate exposure conditions. Hardness usually falls between 150-200 HV, depending on heat treatment and processing.
