Khaleed Stainless is a reputable manufacturer and supplier of Stainless Steel 446 Bolts based in Riyadh, Saudi Arabia. We provide top-notch fastening solutions that are designed for durability and reliability. Stainless Steel 446 is a high-chromium ferritic stainless steel known for its exceptional resistance to oxidation, scaling, and corrosion, even at high temperatures. With its impressive strength and stability, these bolts are perfect for use in tough industrial settings. At Khaleed Stainless, we ensure that our Stainless Steel 446 Bolts are produced under rigorous quality control standards, guaranteeing outstanding performance, a long service life, and dependability in critical industries.
Stainless Steel 446 Bolts are made with a high chromium content (23–27%) and feature low carbon levels, along with carefully controlled amounts of manganese, silicon, and other trace elements. This unique composition gives them remarkable resistance to oxidation, sulfidation, and scaling at temperatures reaching up to 1100°C. In terms of mechanical properties, Stainless Steel 446 boasts a moderate tensile strength of about 485 MPa, a yield strength of around 275 MPa, and good hardness, along with excellent dimensional stability under high heat. While they may not be as tough as austenitic grades, their creep strength and resistance to thermal fatigue make them a reliable option for high-temperature applications.
