Khaleed Stainless, a top-notch manufacturer and supplier based in Riyadh, Saudi Arabia, has built a solid reputation for providing high-quality stainless steel products that cater to a variety of industrial needs. Among their standout offerings, Stainless Steel 321 Bars are particularly prized for their remarkable resistance to high temperatures and intergranular corrosion. Thanks to the addition of titanium, these bars retain their strength and structural integrity even when exposed to elevated temperatures for extended periods. With their durability, toughness, and impressive mechanical properties, Khaleed Stainless’s Stainless Steel 321 Bars are a go-to choice for demanding applications in the chemical, power, automotive, and aerospace sectors.
These bars are primarily made up of iron, chromium (17–19%), nickel (9–12%), and titanium, which helps prevent carbide precipitation during welding or prolonged heating. This specific composition boosts their resistance to oxidation and scaling at temperatures reaching up to 870°C. On the mechanical side, they boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%, ensuring they are tough and reliable. Their ability to maintain strength at high temperatures makes them an excellent option for critical industrial operations.
