Stainless Steel 347H Rectangular Bars are high-carbon austenitic stainless steels that are stabilized with columbium (niobium). They are designed to provide enhanced creep strength and resistance to sensitization. The composition features 17–20% chromium, 9–13% nickel, a maximum of 0.10% carbon, and niobium for stabilization. These bars boast a tensile strength of about 515 MPa, a minimum yield strength of 205 MPa, and excellent oxidation resistance at high temperatures. The increased carbon content significantly boosts high-temperature performance, making 347H suitable for structural applications in extreme conditions.

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.
You’ll find Stainless Steel 347H Rectangular Bars widely utilized in sectors like petroleum refining, chemical processing, power generation, and aerospace, thanks to their strength and stability under thermal stress. Common applications include heat exchangers, high-pressure steam lines, boilers, radiant superheaters, and manifolds. Their ability to resist intergranular corrosion after welding makes them ideal for continuous operation at elevated temperatures. Additionally, they are employed in exhaust stacks, furnace components, and expansion joints, where exposure to high heat and harsh environments calls for long-lasting durability and reliable mechanical performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
