Stainless Steel 347 Hex Bar is an austenitic chromium-nickel alloy that’s stabilized with niobium to prevent carbide precipitation during welding and prolonged exposure to high temperatures. Typically, it contains around 17–19% chromium and 9–13% nickel, which gives it impressive resistance to oxidation and corrosion. This alloy also boasts good tensile strength, toughness, and ductility, along with excellent creep and stress rupture properties at elevated temperatures. Its stable microstructure guarantees reliable mechanical performance even under thermal cycling and harsh service conditions.

SS 347 Hex Bars are widely used in aerospace, chemical processing, and power generation for applications requiring high-temperature resistance, corrosion resistance, and strength. They outperform other grades due to their niobium stabilization, preventing carbide precipitation and ensuring durability.
SS 347 Hex Bars typically exhibit a tensile strength of 515-750 MPa, a yield strength of 205 MPa, and an elongation of 40% minimum. These properties ensure high durability, flexibility, and performance in demanding applications.
SS 347 Hex Bars commonly comply with standards like ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications ensure quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, meeting stringent safety and reliability requirements.
These Stainless Steel 347 Hex Bars are commonly used in applications that demand durability, heat resistance, and corrosion protection. You’ll find them in petrochemical equipment, heat exchangers, pressure vessels, boiler components, and exhaust systems. They’re also utilized in power plants, chemical processing units, and aerospace structures for fasteners, shafts, and structural parts. Thanks to their good weldability and resistance to intergranular corrosion, they’re perfect for fabricated components that face continuous high temperatures and aggressive operating environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
