George Metals in Houston, USA, is a trusted maker and vendor of **Stainless Steel 347 Rectangular Bars**, providing high-quality products for high-temperature and corrosion-resistant uses. Stainless Steel 347 is a niobium-stabilized austenitic stainless steel that provides outstanding resistance to intergranular corrosion as well as high-temperature oxidation. George Metals manufactures these rectangular bars with better dimensional accuracy, surface finish, and mechanical integrity. Made to withstand tough conditions, 347 rectangular bars find extensive applications in chemical processing, aerospace, oil and gas, and power generation industries, where strength, stability, and corrosion resistance are essential.
**Stainless Steel 347 Rectangular Bars** consist of 17–20% chromium, 9–13% nickel, and contain niobium (columbium) for stabilization against precipitation of chromium carbide. This combination provides improved corrosion resistance, particularly in high-temperature conditions. Mechanical properties consist of tensile strength ranging from 515–750 MPa, yield strength of 205–275 MPa, and elongation of approximately 35%. The product, **Stainless Steel 347 Rectangular Bars**, possesses good formability, weldability, and excellent stress rupture and creep resistance, and the material is thus well-suited to service at elevated temperatures continuously and in corrosive environments.
