Aditya Stainless has built a solid reputation as a reliable manufacturer and supplier of Stainless Steel 201 Nuts right in Kolkata, India. They provide top-notch fasteners suitable for a range of applications, including general engineering, structural projects, and industrial uses. Crafted from a unique chromium-nickel-manganese austenitic stainless steel alloy, SS 201 nuts are known for their impressive strength, decent corrosion resistance, and excellent formability. These nuts are perfect for environments with limited exposure to corrosive elements, making them a cost-effective choice compared to SS 304. With a variety of sizes, threads, and finishes available, SS 201 nuts are great for furniture, construction, railways, automotive, appliances, and light fabrication tasks.
Stainless Steel 201 Nuts generally consist of 16–18% chromium, 3.5–5.5% nickel, and 5.5–7.5% manganese, all while keeping carbon content low. This blend gives them decent corrosion resistance and impressive mechanical strength. They boast a tensile strength of at least 520 MPa, a yield strength of at least 275 MPa, and an elongation of at least 40%. While SS 201 may not be as corrosion-resistant as 304 or 316 grades, it still performs admirably in indoor or mildly corrosive settings, making it a dependable and budget-friendly fastening option.
