The Fasteners Mart, which is located in Mumbai, India, is a top supplier and exporter of high-quality industrial fasteners that serve various industries worldwide. One of our best-selling products is the Stainless Steel 304H Washer, which is manufactured using Grade 304H austenitic stainless steel. The washers are available in various shapes such as flat washers, spring washers, and lock washers and possess high strength, durability, and corrosion resistance. The high carbon content of 304H gives it greater tensile strength and is ideal for heavy-duty and high-temperature use.
Stainless Steel 304H Washers consist of iron, chromium (18–20%), nickel (8–10.5%), and carbon (0.04–0.10%), with 304H providing higher carbon content for improved strength at high temperatures. The tensile strength of the washers is approximately 515 MPa, and they possess a yield strength of 205 MPa, with 40% elongation. Their density is 7.9 g/cm³, and they have a melting point of 1400–1450°C. These characteristics give them excellent oxidation resistance, strength, and stability in high-pressure, high-temperature conditions.
