Known for their unwavering dedication to quality, the company produces precision-engineered bars that adhere to international standards, serving industries that require outstanding performance and durability. Thanks to their advanced production techniques, rigorous quality control, and a strong emphasis on customer satisfaction, Phehlukwayo Metal guarantees a reliable supply and exceptional service. Their Stainless Steel 347H Rectangular Bars are perfect for applications that demand excellent corrosion resistance, high-temperature strength, and long-lasting reliability, making them a go-to choice for both industrial and commercial projects.
These Stainless Steel 347H Rectangular Bars are crafted from a high-carbon, chromium-nickel alloy that is stabilized with niobium or tantalum, which boosts their resistance to intergranular corrosion. Typically, they consist of about 17–19% chromium, 9–13% nickel, 0.08% carbon, and small amounts of niobium or tantalum. In terms of mechanical properties, these bars deliver impressive tensile strength, with a yield strength ranging from 310–450 MPa and an ultimate tensile strength between 620–850 MPa. They maintain remarkable toughness and ductility even at high temperatures, along with excellent creep and oxidation resistance, making them ideal for demanding industrial 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 find extensive use in sectors where high-temperature stability and corrosion resistance are essential. You’ll often see them in chemical processing equipment, heat exchangers, boilers, pressure vessels, and furnace components. They’re also utilized in aerospace, power generation, and petrochemical industries because they can endure prolonged exposure to high temperatures without compromising their strength. Additionally, these bars are well-suited for fabricating structural components, machinery parts, and industrial fasteners. Their blend of mechanical strength and durability makes them a reliable choice for a variety of applications.
