1/32” 321 Stainless Steel Coil

Product Overview

The 321 stainless steel coil is a high-performance alloy known for its exceptional durability and high-temperature resistance. This austenitic stainless steel is stabilized with titanium, which prevents carbide precipitation and enhances its ability to withstand oxidation and intergranular corrosion. These properties make it particularly suitable for demanding applications in industries such as aerospace, automotive, heat exchangers, and thermal processing.

The 321 hot rolled stainless steel coil and 321 cold rolled stainless steel coil variants offer customized solutions for different industrial needs. The hot rolled option is ideal for structural components exposed to high temperatures, while the cold rolled version provides precision and smooth finishes for applications requiring superior aesthetics and mechanical properties.

Whether you require a high-strength material for exhaust systems, furnace components, or chemical processing equipment, our 321 stainless steel coil is engineered to deliver optimal performance, durability, and cost efficiency. We provide tailored dimensions, various surface finishes, and certification options to meet the highest industry standards.
