Stainless Steel 347 Hex Bar is a stabilized austenitic stainless steel primarily made up of iron, chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), and niobium or tantalum as stabilizers. This unique blend offers remarkable high-temperature strength, corrosion resistance, and creep resistance. With a tensile strength ranging from approximately 515–620 MPa and a yield strength of 205–275 MPa, it also showcases exceptional toughness. Its ferrite-free austenitic structure ensures stability at elevated temperatures and reduces carbide precipitation along grain boundaries, making it ideal for critical applications that require long-term mechanical reliability and resistance to harsh conditions.
