Product Details
Forging: Forge at 1000°/1050°C. Heat slowly, allowing sufficient time at the forging temperature for the steel to be thoroughly soaked through. Re-heat as often as necessary to keep the temperature above 850°C. After forging cool very slowly, preferably in a furnace.Annealing: Heat uniformly to 800°C, equalize, then furnace cool. (Hardness about 229 Brinell).Stress Relieving: If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700°C, equalize, then cool slowly.Hardening: Heat uniformly to 800/820°C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil.Tempering: Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thicknessTempering °C100150200v250300350HRc64/6363/6262/6160/5957/5654/53Physical Properties: Name of MaterialComposition in % of Weight-Thermal conductivity W/m-kDensity Kg/m^3Melting Point-CMn Si Cr S P Mg---En-31 IS-103 Crl1.50.52 0.22 1.3 0.05 0.05 -46.678101540Mechanical Properties: ElementObjectiveTensile Strength750 N/mm²Yield Stress450 N/mm²Reduction of Area45%Elongation30%Modulus of elasticity215 000 N/mm²Density7.8 Kg/m3Hardness63 HRCHeat Treatment: ElementObjectiveHardening Temperature802¿¿- 860¿¿ CQuenching MediumOilTempering Temperature180¿¿- 225¿¿ CBrinell-Rockwell Hardness59 - 65
