Hindustan Steel Corporation is a trusted stockist and supplier of SS 410, SS 420, and SS 430 stainless steel plates, offering high-performance ferritic and martensitic stainless grades for industrial, architectural, and utility applications. These grades are ideal for moderate corrosion resistance, magnetic properties, machinability, and heat resistance at an economical cost.
We supply 410/420/430 plates in various finishes like 2B, No.4, and mirror, along with MTCs, cut-to-size processing, and export-ready packaging.
These grades belong to the ferritic and martensitic stainless steel families, offering distinct performance characteristics based on chromium content, carbon level, and microstructure.
🔹 SS 410 – Martensitic Stainless Steel
🔹 SS 420 – Hardenable Martensitic Stainless Steel
🔹 SS 430 – Ferritic Stainless Steel
All three grades are magnetic, with SS 430 being non-hardenable, and SS 420 offering the highest hardness post-treatment.
These stainless grades are preferred for cost-sensitive, wear-prone, or aesthetic metal applications, where high corrosion resistance is not critical but strength, finish, or fabrication ease is required.
