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 adhere to international standards. One of their standout offerings is the Stainless Steel 347 Bars, which are prized for their remarkable resistance to intergranular corrosion, impressive strength, and outstanding performance in high-temperature settings. Crafted with precision and durability in mind, these bars are a go-to choice across various industries that demand reliable and long-lasting materials. Khaleed Stainless is committed to delivering Stainless Steel 347 Bars that offer customers cost-effective, durable, and versatile solutions for even the most challenging industrial applications.
These Stainless Steel 347 Bars are primarily made up of iron, chromium (17–19%), nickel (9–13%), and niobium/tantalum, which act as stabilizers to prevent carbide precipitation. This unique chemical composition boosts their resistance to oxidation and corrosion, especially at elevated temperatures. On the mechanical side, these bars boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%, ensuring they remain tough and stable under demanding conditions. They also excel in creep and stress-rupture resistance, making them a reliable choice for heavy-duty, high-temperature applications.
