Supported by state-of-the-art infrastructure and a talented team, Neil Metals offers tailored stainless steel solutions to clients in various sectors, including aerospace, chemical processing, and thermal equipment manufacturing.
Stainless Steel 321 Round Bars and Rods are a type of titanium-stabilized austenitic stainless steel, containing about 17–19% chromium, 9–12% nickel, and titanium levels that are at least five times the carbon content to avoid carbide precipitation. These bars boast a tensile strength of around 515 MPa and a minimum yield strength of 205 MPa, along with impressive oxidation resistance up to 870°C. The titanium stabilization significantly improves resistance to intergranular corrosion after welding, making this grade ideal for extended use in high-temperature environments.
