Anucha Metals, a reputable manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 321 Bars and Rods that adhere to international standards for durability and performance. With a strong background in precision engineering, Anucha Metals guarantees dependable products for demanding applications across various industries. Stainless Steel 321, an austenitic stainless steel that’s stabilized with titanium, is specifically engineered to resist intergranular corrosion even after being exposed to high temperatures. Renowned for its strength, toughness, and thermal stability, Stainless Steel 321 Bars and Rods find extensive use in the petrochemical, power generation, chemical processing, and construction sectors.
These bars and rods are primarily made up of iron, with 17–19% chromium, 9–12% nickel, and titanium, along with trace amounts of carbon, manganese, silicon, phosphorus, and sulfur. The titanium stabilization helps prevent carbide precipitation during welding or high-temperature applications, ensuring long-lasting corrosion resistance. They boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, all while maintaining toughness at both high and low temperatures. Their remarkable mechanical properties, paired with excellent oxidation resistance, make them a reliable choice for critical engineering tasks.
