HRS Ferritic is a globally reliable Stainless Steel 405 plate stockist and supplier, also known as a leading stockist of top stainless-steel products. We are specialists in ferritic stainless-steel products that conform to international standards. With our advanced processing capabilities, we ensure consistent quality, corrosion resistance and reliable performance.
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.
Each element in SS 405 plays a precise role in delivering thermal stability, weldability and corrosion performance.

High-quality flat plates in various thicknesses for industrial and high-temperature applications.
Hot rolled, annealed and pickled for better corrosion resistance and enhanced weldability.
Preferred for architectural and infrastructural applications requiring a smooth finish.
Custom-fabricated plates to meet specific requirements for any project.
11.5–14.5% — Maintains ferritic structure and provides corrosion resistance.
0.10–0.30% — Key addition for high-temperature oxidation resistance.
≤ 0.08% — Low level prevents carbide formation and ensures weldability.
Balance — Ensures magnetic behaviour and stable mechanical properties.
380–450 MPa — Reliable for structural and thermal applications.
170–240 MPa — Consistent for forming and fabrication.
20–25% — Good ductility for forming processes.
170–200 HB — Ensures machinability and surface quality.
A variety of SS 405 plate types to meet different operational and project requirements.
The aluminium addition in SS 405 distinguishes it from other ferritic grades, providing superior high-temperature oxidation resistance while the low carbon content ensures excellent weldability.
