Khaleed Stainless is your go-to manufacturer and supplier of Stainless Steel 440C Fasteners right here in Riyadh, Saudi Arabia. We pride ourselves on delivering top-notch fastening solutions that are built for high-strength and wear-resistant applications. Stainless Steel 440C is a high-carbon martensitic stainless steel known for its impressive hardness, tensile strength, and exceptional wear resistance. Our 440C fasteners are crafted to provide long-lasting performance, even in the toughest conditions. At Khaleed Stainless, we make sure that every Stainless Steel 440C Fastener meets international quality standards, making them perfect for industries like aerospace, automotive, petrochemical, marine, and engineering.
Stainless Steel 440C Fasteners are made with a high carbon content (0.95–1.20%) and chromium (16–18%), along with trace amounts of molybdenum, manganese, and silicon. This unique blend gives them remarkable hardness, abrasion resistance, and strength. They boast a tensile strength of up to 760–1000 MPa, a yield strength of around 450–500 MPa, and can reach a hardness of up to 58 HRC after heat treatment. While they may not resist corrosion as well as austenitic grades, 440C fasteners shine in terms of strength, toughness, and wear resistance, making them a reliable choice for critical fastening applications in demanding mechanical environments.
