Stainless Steel 347 Round Bar is an austenitic stainless steel product stabilized with columbium and tantalum, giving it excellent resistance to intergranular corrosion after exposure to high temperatures. Known for its balance of strength, durability, and oxidation resistance, it performs well in environments up to 1500°F. Preston Pipes & Alloys is a leading Stainless Steel 347 round bar suppliers, offering bars with a precise chemical composition containing elements like manganese, carbon, phosphorus, silicon, chromium, sulfur, nickel, columbium with tantalum, cobalt, and iron. These bars have excellent mechanical properties, including strong tensile and yield strength, good elongation, and a high melting point, making them perfect for demanding industrial applications.
We offer stainless steel 347 bar in a variety of specifications to suit different project needs. Sizes range from small-diameter precision bars to large structural sections. They come in shapes such as round, hex, or square, and in finishes like bright, polished, or black. Common manufacturing procedures include hot rolling, cold drawing, centerless grinding, and peeling which improve dimensional accuracy and surface polish. Each bar meets international standards, ensuring compatibility with global projects and high-performance requirements.
The 347 stainless steel round bar offers strong resistance to heat and corrosion, along with good mechanical strength. This makes it appropriate for woven or welded screens in mining and quarrying activities, as well as springs that require flexibility and resilience. In commercial kitchens, it serves well in benches, troughs, sinks, and equipment due to its hygiene and durability. It is also suitable for manufacturing chemical containers and transport vessels, as it is resistant to harsh media and high temperatures. The 347 stainless steel bar is reliable in a wide range of applications, including heavy-duty industrial use and hygienic food processing environments.
Every 347 round bar goes through stringent quality inspections, including mechanical testing, dimensional inspection and corrosion resistance verification. Ultrasonic and surface flaw detection guarantees defect-free delivery. Our team packs every bar using industry-approved methods such as wooden boxes, steel strips, or plastic wrapping to prevent damage during transit. These standards help maintain the integrity of each bar from mill to site. For dependable performance and long-lasting strength, choose us as your stainless steel 347 round bar supplier.
