The Differences Between Ductile Iron and Gray Iron Jun 18, 2015 · There are many grades of gray iron as per the ASTM A48 standard. While gray iron does not have a measurable yield strength, the range for tensile strength is 20,000 psi 60,000 psi. Impact Ductile iron has a greater resistance to impacts, and is able to resist a minimum of 7 foot pounds of impact (versus 2 pounds of impact for gray iron).
The thermal conductivity of gray cast iron ASTM A48 is 53 W/ (m.K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or ), measured in W/m.K. It is a measure of a substances ability to transfer heat through a material by conduction.ASTM A48 CLASS 35 CAST IRON - Iron foundryASTM A48 CLASS 35 CAST IRON.
