1.2083 Forged Flat Bar 4Cr13 Manufacturer Special Tool Plastic Mold Steel¹

Product Description Product Description 1.2083 Forged Flat Bar  4Cr13 Plastic Mold Steel 4201.2083 steel is a martensitic stainless steel with 12% Chromium which is sufficient to give good corrosive resistance properties. It's best corrosive resistance is when hardened and surface is ground or polished. It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades). Martensitic Grades are known for high hardness and allowances must be made for poor weldability and usually allowances for a final harden and temper treatment.  420/1.2083 steel is magnetic and welding is not recommended.Equivalent Grades:StandardAISI/SAEW.Nr/DINJISGBGrade4201.2083SUJ420J24Cr13 Chemical Composition Of 1.2083 (%)CSiMnMoPSCr0.38-0.45≤1.00≤1.00≤1.00≤0.03≤0.0312.00-13.50 Heat Treatment of 1.2083 SteelAnnealing: 760 to 800oC, slow cooling in furnace (10-20oC/hr), down to approx. 600oC, cooling in air.
