Khaleed Stainless stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, specializing in high-quality Stainless Steel 310H Nuts designed for tough industrial applications. These high-carbon fasteners are made from SS 310H, a heat-resistant alloy celebrated for its remarkable strength, creep resistance, and outstanding performance under high temperatures. Built to meet international quality standards, SS 310H Nuts excel in resisting oxidation, corrosion, and scaling, even in the harshest conditions. With precise threading and impressive durability, our nuts are a go-to choice in power generation, petrochemical, and furnace construction, making Khaleed Stainless a reliable partner for high-performance fastening solutions in critical settings.
Stainless Steel 310H Nuts are composed of 24–26% chromium, 19–22% nickel, and a higher carbon content of up to 0.10%, which together provide remarkable strength and thermal stability. They also contain ≤2% manganese, ≤1.5% silicon, and ≤0.045% phosphorus, all of which enhance oxidation resistance. These nuts boast a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of around 40%, with a hardness rating of approximately 217 HB. The high carbon and nickel content in SS 310H ensures superior creep resistance, making these nuts dependable for high-pressure, high-temperature applications where long-lasting durability and secure fastening are crucial.
