What is Grey Cast Iron? - Willman Industries

Other ASTM standards that deal with gray iron include ASTM A126,ASTM A278,and ASTM A319.Class 20 grey iron has a ferrite matrix and a high carbon equivalent.Higher strength gray irons,up to class 40,have lower carbon equivalents and a pearlite matrix.To get grey iron above class 40 requires alloying to provide solid solution strengthening.What is Grey Cast Iron? - Willman IndustriesOther ASTM standards that deal with gray iron include ASTM A126,ASTM A278,and ASTM A319.Class 20 grey iron has a ferrite matrix and a high carbon equivalent.Higher strength gray irons,up to class 40,have lower carbon equivalents and a pearlite matrix.To get grey iron above class 40 requires alloying to provide solid solution strengthening.What are Thermal Properties of Cast Iron - Definition Thermal Conductivity of Cast Irons.The thermal conductivity of gray cast iron ASTM A48 is 53 W/(m.K).The thermal conductivity of martensitic white cast iron (ASTM A532 Class 1 Type A) is 15 30 W/(m.K).The thermal conductivity of malleable cast iron is approximately 40 W/(m.K).The thermal conductivity of ductile cast iron is 36 W/(m.K).
