Khaleed Stainless, a top-notch manufacturer and supplier based in Riyadh, Saudi Arabia, has earned a solid reputation for delivering high-quality stainless steel products that align with global industry standards. One of their standout offerings is the Stainless Steel 321 Coils, which are highly regarded for their exceptional resistance to oxidation, scaling, and intergranular corrosion. Thanks to the addition of titanium, these coils are engineered to excel even when exposed to high temperatures for extended periods. Renowned for their durability, toughness, and ease of welding, Khaleed Stainless’s Stainless Steel 321 Coils are a go-to choice in industries that prioritize reliability, strength, and long-lasting performance.
These coils are made up of iron, chromium (17–19%), nickel (9–12%), and titanium, which acts as a stabilizer to prevent carbide precipitation during welding or heating. This special blend gives them remarkable resistance to high-temperature corrosion and oxidation, even up to 870°C. On the mechanical side, they boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of roughly 40%. Their unique combination of strength, stability, and creep resistance makes them perfect for tough applications in challenging environments.
