Punit Fasteners, a well-respected manufacturer and supplier located in Delhi, India, specializes in providing affordable and durable Stainless Steel 201 Washers tailored for a variety of industrial and structural applications. SS 201 is an austenitic stainless steel alloy known for its decent corrosion resistance, impressive toughness, and robust mechanical strength. These washers are perfect for environments that aren’t overly aggressive, where moisture and mild chemicals might be present. Punit Fasteners guarantees precise dimensions, smooth finishes, and consistent quality in every batch. With a range of sizes, types (flat, spring, lock), and thicknesses available, SS 201 washers are a dependable choice for everyday fastening needs.
Stainless Steel 201 Washers are made up of about 16–18% chromium, 3.5–5.5% nickel, and 5.5–7.5% manganese. This blend provides moderate corrosion resistance, particularly in indoor or slightly corrosive settings. SS 201 boasts a tensile strength of roughly 520–750 MPa and a yield strength of around 275 MPa. It showcases excellent hardness, formability, and wear resistance, making it ideal for structural and load-distribution tasks. While it may not be as corrosion-resistant as 304 or 316 stainless steel, SS 201 washers are a budget-friendly choice for situations where strength and cost-effectiveness take precedence over extreme corrosion resistance.
