Stainless Steel 347 Hex Bar is a stabilized austenitic stainless steel with chromium (17–20%), nickel (9–13%), columbium (stabilizing element), and minor amounts of carbon, manganese, silicon, phosphorus, and sulfur. It has a tensile strength of about 515 MPa and yield strength of 205 MPa, with elongation at 35%. It provides better resistance to intergranular corrosion following high-temperature exposure, with structural integrity in hostile environments. The property’s high mechanical strength and weldability make it suitable for challenging industrial usage.

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.
Stainless Steel 347 Hex Bar finds ample application in corrosive and high-temperature applications like chemical processing facilities, heat exchangers, boilers, and aircraft. It is best suited for equipment that should withstand corrosive media and high thermal cycles and is used in refinery equipment, food processing machines, and marine hardware. With its high resistance to creep and oxidation, it is also good for power generation plant pressure vessels and piping systems. Its strength, corrosion resistance, and versatility make it the first choice in industries calling for reliable long-lasting stainless steel solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
