Stainless Steel 347 Hex Bars are among the high-end stainless steel products that George Metals, a well-known manufacturer and supplier with headquarters in Houston, Texas, is known for providing. George Metals serves vital industries like petrochemical, aerospace, power generation, and marine engineering and has a stellar reputation for quality. Their 347 Hex Bars of stainless steel are made to exacting industry standards, guaranteeing exceptional resistance to corrosion and high temperatures. George Metals is the go-to supplier for stainless steel hex bars in both domestic and foreign markets because of their reliable delivery, tailored solutions, and technical know-how.
The main constituents of stainless steel 347 Hex Bars are 17–20% Chromium, 9–13% Nickel, and additional Columbium (Niobium) for improved resistance to intergranular corrosion. Carbon (≤ 0.08%), silicon, and manganese are examples of trace elements. At high temperatures, this stabilised austenitic stainless steel provides exceptional strength and resistance to oxidation. Mechanical characteristics include a 35% elongation, a yield strength of 205 MPa, and a tensile strength of about 515 MPa. 347 stainless steel is appropriate for applications involving thermal cycling and high heat exposure because it maintains its toughness even under cryogenic conditions.

High-temperature and corrosive service environments are perfect for stainless steel 347 Hex Bars. Heat exchangers, boiler tubes, aircraft exhaust manifolds, and chemical processing equipment all make extensive use of them. These bars are ideal for applications involving continuous and cyclic heating because of their exceptional resistance to intergranular corrosion and oxidation. Because 347 hex bars can function dependably under pressure and heat, they are used in the food processing, pharmaceutical, aerospace, and petroleum refining industries. They are also a preferred material for industrial plants’ pressure vessels, furnace components, and flue gas scrubbers due to their machinability and weldability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
