Khaleed Stainless stands out as a top manufacturer and supplier of Stainless Steel 347H Bars in Riyadh, Saudi Arabia, known for delivering high-quality products designed for demanding applications. Stainless Steel 347H is a stabilized austenitic stainless steel with a higher carbon content, which gives it improved creep strength and resistance to sensitization at high temperatures. These bars find their place in various industries, including chemical processing, refineries, oil & gas, power generation, and pharmaceuticals. Thanks to their exceptional mechanical properties and outstanding corrosion resistance, SS 347H Bars offer durability, reliability, and strength even in the toughest conditions.
Stainless Steel 347H Bars are made up of chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), and niobium/tantalum, which help stabilize against carbide precipitation, along with controlled amounts of manganese, silicon, phosphorus, and sulfur. They boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. These bars excel in high-temperature strength, provide excellent oxidation resistance up to 1000°C, and show enhanced creep and stress rupture performance, making them perfect for extended use in extreme environments.
