Stainless Steel 309 Round Bars Supplier

Stainless Steel 309 is an austenitic chromium-nickel alloy with exceptional corrosion and heat resistance. It is also easily rolled, stamped, and drawn, making it perfect for various applications. Stainless Steel 309 can also be found in the sheet, coil, and plate. Stainless Steel 309 Round Bars are commonly available in various lengths, dimensions, and forms. They are manufactured using top-quality raw materials and undergo a quality check by quality inspectors before being packaged for global distribution.

Moreover, these bars are available at competitive prices. Stainless Steel 309 Round Bars are highly resistant to corrosion. They are used in various applications, including architecture, food processing, and dairy. They are also widely used in the petrochemical and chemical industries. Their strength makes them an ideal choice for heat-resistant applications. They may also be utilized in welding procedures.

Stainless Steel 309 Round Bars can be hardened and annealed at temperatures up to 1121 degrees Celsius. Their tensile strength, hardness, and elongation are also very high. In addition to these benefits, 309 has excellent resistance to sulfur attack.

The chromium and nickel content in Stainless Steel 309 allows it to withstand higher temperatures and is more corrosion resistant than Stainless Steel 304 Round Bars counterpart. This stainless steel grade is also extremely weldable. Because it has a high chromium and nickel content, it is often used in high-temperature containers and furnace parts. Stainless Steel 309 Round Bars can be found in various shapes, including flat, bright, and forged rods. Stainless Steel 309 Round Bars are sold in ASTM A276 and UNS S30900.
