Khaleed Stainless is a reputable manufacturer and supplier of high-performance Stainless Steel 321H Bars based in Riyadh, Saudi Arabia. They’ve built a solid reputation for their dedication to quality and precision, ensuring that their bars not only meet international standards but also excel in high-temperature settings. The Stainless Steel 321H Bars are a high-carbon variant of the 321 stainless steel, specifically engineered for improved strength and creep resistance. With a wealth of technical expertise and a strong focus on customer satisfaction, Khaleed Stainless caters to industries like oil & gas, petrochemicals, and power generation, providing reliable and durable bar solutions that are perfectly suited for demanding applications.
These Stainless Steel 321H Bars are made up of iron, 17–19% chromium, 9–12% nickel, and a higher carbon content (0.04–0.10%) compared to standard 321, which boosts their high-temperature strength. To enhance the alloy’s stability and prevent carbide precipitation, titanium is also included. These bars boast a tensile strength of about 515 MPa, a minimum yield strength of 205 MPa, and an elongation of 40%. Their superior mechanical properties make them ideal for environments that require prolonged exposure to high temperatures and pressure without compromising structural integrity.
