Plastic Mould Steel

Product Description

Plastic Mold Steel offered by us has good dimensional stability during heating, polishability, impact strength, and wear properties. Different grades of mold steel will provide superior polishability or machinability within the broad category. The majority of mold steel comes pre-hardened. This steel is very easy to use and widely appreciated by people, in the market. Plastic Mold Steel has better corrosion resistance, making them ideal for molding chemically aggressive polymers. This steel is very effective as well as economical to use.Product details Minimum Order Quantity 200 Kilogram Cooling Furnace Hardening 840-870 Deg C Hardness After Quenching 51 HRC Quenching Polymer or Oil Usage/Application Automobile Industry Surface Finish Polish Hardness max. 235 HB Soft Annealing 710-740 Deg C Chemical Composition - (Typical Analysis in %) C Si Mn P S Cr Ni Mo 0.35-0.45 0.20-0.40 1.30-1.60 0.030max 0.030max 1.80-2.10 1.90-1.20 0.15-0.35 Physical Properties: Coefficient of Thermal Expansion at C 10 m / (m*K) 20-100 11.2 20-200 12.8 20-300 13.5 20-400 13.7 20-500 14.3 20-600 14.7 20-700 14.9 Thermal Conductivity at C W / (m*K) 20 35 350 34 700 33 Tempering after quenching 100 200 300 400 500 600 700 HRC 51.5 50.2 48 46.2 43 39 29
