Khaleed Stainless is a reliable manufacturer and supplier of Stainless Steel 440B Stud Bolts based in Riyadh, Saudi Arabia. We specialize in providing precision-engineered fastening solutions tailored for critical industrial applications. Stainless Steel 440B is a high-carbon martensitic stainless steel, celebrated for its remarkable blend of hardness, strength, and decent corrosion resistance. Our 440B stud bolts are crafted to endure tough service conditions, ensuring they deliver durability and performance. At Khaleed Stainless, we offer Stainless Steel 440B Stud Bolts that comply with international standards, making them perfect for aerospace, petrochemical, marine, and engineering sectors.
Stainless Steel 440B Stud Bolts consist of carbon (0.75–0.95%) and chromium (16–18%), along with trace amounts of manganese, silicon, and molybdenum. This unique composition grants them high wear resistance, outstanding hardness, and dependable strength. These bolts showcase a tensile strength of 700–800 MPa, a yield strength of about 400–450 MPa, and can reach hardness levels of up to 55 HRC after heat treatment. While they offer improved corrosion resistance compared to 440C, they also retain toughness and stability, making them suitable for moderately corrosive and high-stress environments.
