Sumit Impex is a leading manufacturer and supplier of stainless steel 304 bolts, which are known for their superior composition and durability. These bolts are made of austenitic stainless steel, which contains 18% chromium and 8% nickel, making them very resistant to corrosion and oxidation. The use of nickel also contributes to the bolts’ non-magnetic qualities, making them appropriate for applications where magnetism is an issue. Our SS 304 bolts are designed to have remarkable mechanical qualities, with a minimum yield strength of 170 MPa for 304L and up to 205 MPa for 304 and 304H grades. These bolts also have a tensile strength of up to 515 MPa, a remarkable 40% elongation capacity, and a maximum hardness of 201 HB. Our fasteners’ outstanding performance is achieved by a meticulous blend of chemical ingredients, including carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, and nitrogen, all of which contribute to their strength and durability.
