Khaleed Stainless stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, specializing in high-quality Stainless Steel 348H Bars. These bars are known for their impressive strength, durability, and ability to withstand tough service conditions. They’re specifically crafted for applications that demand exceptional performance at high temperatures and in corrosive environments. You’ll find Stainless Steel 348H Bars from Khaleed Stainless being widely utilized in the petrochemical, chemical, power generation, and oil and gas industries, all manufactured with precision to meet international standards. Their stability, toughness, and long lifespan make them a go-to choice for critical industrial applications.
These bars are made up of iron, chromium (17–19%), nickel (9–13%), and niobium (columbium), featuring a higher carbon content than grade 348. This extra carbon boosts their creep strength, making them perfect for prolonged exposure to high temperatures. Plus, the addition of niobium helps stabilize the alloy, preventing issues like carbide precipitation and intergranular corrosion. On the mechanical side, these bars deliver a tensile strength of around 550 MPa, a yield strength of 240 MPa, and good elongation, ensuring they remain tough, stable, and resistant to thermal and mechanical stress.
