Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 440B Fasteners in Riyadh, Saudi Arabia. We pride ourselves on delivering exceptional fastening solutions tailored for high-performance industries. Stainless Steel 440B is a high-carbon martensitic stainless steel known for its impressive balance of hardness, toughness, and resistance to corrosion. Our 440B fasteners are crafted with precision to ensure they offer strength, reliability, and a long lifespan. At Khaleed Stainless, we guarantee that every Stainless Steel 440B Fastener adheres to global quality standards, making them ideal for applications in aerospace, automotive, petrochemical, engineering, and marine sectors.
Stainless Steel 440B Fasteners are made up of carbon (0.75–0.95%), chromium (16–18%), along with carefully controlled amounts of manganese, silicon, and molybdenum. This unique composition results in a blend of hardness, moderate corrosion resistance, and high wear resistance. These fasteners boast a tensile strength of 700–800 MPa, a yield strength of around 400–450 MPa, and can reach a hardness of up to 55 HRC after heat treatment. While they may not be as corrosion-resistant as austenitic grades, 440B fasteners shine in terms of mechanical strength and abrasion resistance, making them a dependable choice for demanding industrial settings.
