Grade Overview

What is Stainless Steel 405 Plate / AISI 405 Plate?

Stainless Steel 405 (AISI 405) is a ferritic stainless-steel alloy designed to provide enhanced oxidation resistance and excellent thermal stability. It contains aluminium as an enhancing component, which improves its capacity to withstand extreme temperatures and reduces the risk of hardening when welding. Widely used in industrial heating, automotive chemical processing and general manufacturing.
