The Fasteners Mart, headquartered in Mumbai, India, is a prominent distributor and exporter of high-grade industrial fasteners for a wide spectrum of industries all over the world. Amongst our top-line products are Stainless Steel 304H Nuts, which are produced using Grade 304H austenitic stainless steel. These nuts can be found in different shapes including hex, square, and heavy-duty types. Due to their high carbon content, 304H nuts provide improved tensile strength, corrosion resistance, and high-temperature stability, which makes them suitable for critical applications in harsh industrial environments.
Stainless Steel 304H Nuts mainly consist of iron, chromium (18-20%), nickel (8-10.5%), and carbon (0.04-0.10%), which gives them high strength and oxidation resistance at high temperatures. Stainless Steel 304H Nuts have a tensile strength of around 515 MPa and a yield strength of 205 MPa. Physical properties are a density of 7.9 g/cm³ and a melting point of 1400–1450°C. These properties guarantee optimum performance in corrosive and high-temperature conditions, where toughness and strength are needed.
