Product Description H11 Tool Steel/1.2343/SKD6H11 Tool Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment.It contains less vanadium than the widely-used H13 tool steel,the steel has very good toughness,good thermal strength, thermal fatigue properties and a certain wear resistence under the condition of medium temperature.Air quenching under the low austenitizing temperature,heat treatment deformation is small ,tendency to produce iron oxide is small when air quenching,and it can resist erosion of the molten aluminum. 1.Size Range for H11 Tool SteelH11 Steel Round Bar: diameter 80mm~420mmH11 Steel Plate: thickness 25mm~400mm x width 200mm~800mmDelivery Condition:Tured Round Bar,Milling Plate,Black,requiremts for customers.Spheroidizing Annealing,ESR material.2.H11 Tool Steel Equivalent GradesCountryUSAGermanJapanChinaStandardASTM A681W-nr.DINJISG4404GB/T1299-2000GradesH111.2343X38CrMoV51SKD64Cr5MoSiV3.H11 Tool Steel Chemical CompositionGradesC%Si%Mn%P%S%Cr%Mo%V%H110.32~0.430.80~1.200.20~0.50≤0.03≤0.034.75~5.501.10~1.600.30~0.601.2343/X38CrMoV510.36~0.420.90~1.200.30~0.50≤0.03≤0.034.80~5.501.10~1.400.25~0.50SKD60.35~0.420.80~1.20≤0.50≤0.030≤0.0204.50~5.501.00~1.500.30~0.504.H11 Tool Steel Physical PropertiesPhysical properties of H11 Tool Steel are listed in the tables below.The density is 7.69g/cm3 ,and the specific heat at the constant pressure(20°C) Cp is 459.8J/(kg·K).Critical temperature of H11 Tool SteelCritical pointAc1Ac3Ar1Ar3MsMfTemp.(approximation)1567°F(853°C)1673°F(912°C)1328°F(720°C)1423°F(773°C)590°F(310°C)217°F(103°C)Coefficient of linear thermal expansionTemp./ °C20~10020~20020~30020~40020~50020~60020~700Coefficient/°C-1(x10-6)10.010.911.412.212.813.313.6Thermal conductivity of H11Temp. /°C100200300400500600700λ/W?(m?K)-125.927.628.428.027.626.725.9Elastic modulus of H11Temp. /°C20100200300400500E/MPa2270002210002160002080002000001920005.Forging of H11 Tool SteelItemsHeating temperatureStarting forging temperatureFinal forging temperatureCoolingIngot2084~2156°F(1140~1180°C)2012~2102°F(1100~1150°C)≥1652°F(≥900°C)Cooling in hole or sandBillet2048~2102°F(1120~1150°C)958~2012°F(1070~1100°C)1562~1652°F(850~900°C)Cooling in hole or sand6.Heat treatment of H11 Tool Steel Soft AnnealingTemperatureCoolingHardness1382~1470°F(750~799°C)Furnace 20°F per hour to 1200°F(649°C),then air cooling.230HB Max Stress RelievingTemperatureCoolingHardness1200°F(649°C) for 2 hoursCool slowly to 930°F(499°C) in air230HB Max HardeningTemperatureCoolingHardness1850~1880°F(1010~1027°C) Hold at temperature for 30 minutesVacuum quench to 1000°F(538°C),then cool to below150°F(65°C)54HRC Max Quenched TemperingTemp.752°F(400°C)932°F(500°C)1022°F(550°C)1112°F(600°C)1202°F(650°C)1292°F(700°C)HardnessHRC525452483831-Tempering hardness is approximate and based on two hours at temperature.-Optimal heat treatment parameters should be followed to achieve maximum potential mold life7.Applications of H11 Tool SteelH11 tool steel is recommended for hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling. The tools produced from chromium hot-work steels can be cooled using water without damage as these steels have low carbon and alloy contents.In addition,due to its good medium thermal strength,H11 also has been used as structural parts in manufacture of aircraft and rockets under the working temperature 752~932°F (400~500°C).
