12% Chromium Ferritic Grade · Excellent Corrosion Resistance · Abrasion Resistant · Global Supply
HRS Ferritic has a strong reputation in the stainless steel and alloy industry, recognized as a 3CR12 Plates Supplier, Stockist and Importer. 3CR12 Plate is a ferritic steel plate with approximately 12% chromium. It offers excellent corrosion resistance, moderate heat resistance and abrasion resistance, making it a good alternative to austenitic steels. Its ferritic structure forms a protective oxide layer on the surface, providing resistance against oxidation, corrosion, and stress cracking.
3CR12 is preferred by industries because of its ferritic structure, which provides excellent weldability and resistance to stress cracking. The protective chromium oxide layer guards against corrosion in mildly aggressive environments, making it a reliable and cost-effective solution across many industrial sectors.
Each element in 3CR12 plate plays a precise role in delivering corrosion resistance, strength and excellent weldability.
