Anucha Metals, a top-notch manufacturer and supplier based in Bangkok, Thailand, specializes in high-quality Stainless Steel 321 Rectangular Bars that are crafted to meet international standards for strength and durability. These bars are celebrated for their outstanding resistance to intergranular corrosion, oxidation, and extreme temperatures. Stabilized with titanium, they effectively prevent carbide precipitation during welding. With their reliable performance and longevity, Stainless Steel 321 Rectangular Bars are perfect for demanding applications. Anucha Metals caters to various industries, including chemical processing, petrochemical, power generation, marine, and aerospace, providing precision-engineered stainless steel solutions that blend durability, corrosion resistance, and cost-effectiveness.
Stainless Steel 321 Rectangular Bars are made from an austenitic stainless steel alloy that contains 17–19% chromium, 9–12% nickel, titanium stabilization, and controlled carbon content. This unique composition guarantees excellent resistance to intergranular corrosion and high-temperature oxidation. On the mechanical side, they boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 35%. The addition of titanium not only enhances weldability and stability at high temperatures but also ensures toughness, creep resistance, and dimensional stability, making these bars ideal for critical industrial applications.
