Dhruv Metals, located in Hyderabad, India, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Stainless Steel 347H Rectangular Bars. These bars are celebrated for their outstanding performance in high-temperature and corrosive settings, crafted with meticulous quality control to align with global standards. Stainless Steel 347H is an austenitic grade that’s stabilized with niobium (also known as columbium) and boasts a higher carbon content, which boosts its strength and resistance to intergranular corrosion. Dhruv Metals guarantees dependable delivery of SS 347H rectangular bars, catering to industries that demand durable and heat-resistant stainless steel products.
The composition of Stainless Steel 347H Rectangular Bars includes chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), and niobium (at least ten times the carbon content), along with trace amounts of manganese, silicon, phosphorus, and sulfur. This blend results in impressive tensile strength exceeding 515 MPa, a yield strength of at least 205 MPa, elongation around 40%, and a Brinell hardness reaching up to 201 HB. The niobium stabilization effectively prevents carbide precipitation during welding, ensuring high creep resistance and mechanical integrity even at elevated temperatures.

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 applications across various industries, including power generation, petrochemical, and chemical processing. They’re frequently utilized in boiler tubes, heat exchangers, furnace components, and superheaters, where resistance to oxidation, corrosion, and thermal creep is crucial. These bars also play a vital role in aerospace and refinery equipment that undergoes frequent thermal cycling. Their excellent weldability and resistance to intergranular attack make them ideal for critical components that require long-lasting reliability in tough conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
