Stainless Steel 347H Hex Bars are among the high-end stainless steel products offered by George Metals, a reputable manufacturer and supplier with headquarters in Houston, Texas, in the USA. These hex bars are in high demand across a range of industries due to their exceptional high-temperature performance, durability, and accuracy. George Metals guarantees that every 347H bar satisfies strict quality and ASTM standards, meeting the demands of industries like thermal processing, power generation, and petrochemicals. George Metals is a preferred supplier in both domestic and foreign markets because of their innovative, timely, and customer-focused stainless steel solutions that ensure long-term dependability.
Stabilised austenitic stainless steel with a higher carbon content for strength at high temperatures is what makes stainless steel 347H Hex Bars so strong. For carbide stabilisation, they contain roughly 17–20% chromium, 9–13% nickel, 0.04–0.10% carbon, and columbium (niobium). At high temperatures, these bars provide exceptional resistance to oxidation and intergranular corrosion. The material has good elongation and toughness, a yield strength of 205 MPa, and a tensile strength of about 515 MPa. 347H bars are appropriate for demanding and high-temperature service conditions because they retain their structural integrity under pressure and thermal cycling.

Because of their exceptional creep resistance and mechanical strength, stainless steel 347H Hex Bars are frequently used in high-temperature and high-pressure applications. These bars are used to fabricate boilers, superheaters, pressure vessels, and reactor components in the petrochemical, oil and gas, thermal processing, heat exchanger, and power plant industries. They are appropriate for welded structures exposed to high temperatures because of their capacity to withstand intergranular corrosion following welding. Furthermore, 347H is used in the chemical, pharmaceutical, and food processing industries where resistance to heat and corrosion is crucial. Additionally, because of its hexagonal shape, it is perfect for precision manufacturing and machining of important parts.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
