Rupal Metals is a well-respected manufacturer and supplier of Stainless Steel 347H Rectangular Bars based in Delhi, India. They provide top-quality stainless steel products designed for outstanding performance in high-temperature and corrosive settings. SS 347H is a high-carbon, niobium-stabilized austenitic stainless steel that excels in elevated temperature applications. These rectangular bars boast impressive strength, excellent weldability, and strong resistance to intergranular corrosion. Rupal Metals offers SS 347H rectangular bars in a variety of sizes and specifications, serving industries like power generation, heat treatment, chemical processing, and petroleum refining, where thermal stability and mechanical durability are crucial.
Stainless Steel 347H Rectangular Bars are made up of Chromium (17–20%), Nickel (9–13%), Carbon (0.04–0.10%), and Columbium (Nb) for stabilization, along with Manganese, Silicon, and trace amounts of Phosphorus and Sulfur. This grade provides a tensile strength of about 515 MPa and a yield strength of 205 MPa, along with excellent resistance to high-temperature creep. SS 347H maintains its structural integrity even under prolonged thermal exposure and resists intergranular corrosion post-welding. The rectangular shape ensures flat surface contact, making these bars perfect for structural applications, supports, and fabrication in challenging thermal and corrosive environments.

To maintain Stainless Steel 347H Rectangular Bars, regularly clean them with a mild detergent and water to remove contaminants. Avoid exposure to harsh chemicals and ensure proper storage in dry, well-ventilated areas to prevent corrosion.
Yes, Stainless Steel 347H Rectangular Bars are fully recyclable. Their high-quality material allows for efficient reuse in manufacturing processes, contributing to sustainability and reducing environmental impact.
Stainless Steel 347H Rectangular Bars generally do not require corrosion protection coatings due to their inherent resistance to oxidation and corrosion. However, additional coatings may be used in highly aggressive environments for enhanced protection.
Stainless Steel 347H Rectangular Bars are perfect for high-temperature and corrosive service conditions. They find common use in heat exchangers, boiler tubes, furnace components, superheater tubes, pressure vessels, and exhaust manifolds. These bars are also utilized in chemical processing plants, power generation facilities, aerospace systems, and refineries where materials face thermal cycling and corrosive media. The rectangular profile allows for easy fabrication and structural stability, making it ideal for frames, supports, and flat-mounted components in demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
