The presence of graphite flakes also gives gray iron excellent machinability and self-lubricating properties. ASTM Specification A-48 lists several classes of gray cast irons based on tensile strength. A range from 20 to 60 ksi tensile strength is identified. Cast irons above 40 ksi tensile ...

The role of silicon, manganese and chromium on the mechanical properties of the investigated cast iron has shown that increasing silicon and carbon equivalent results in a decrease in the tensile strength and a decrease in the hardness. The increase in the manganese and chromium additions results ...

The average sphere radius is about 0.4 mm and they are commonly made of glass, ceramic, cast iron, or steel. A prerequisite for the sphere’s material is the higher hardness compared to the shot-peened material. A higher difference between the sphere’s and the target’s hardness yield ...
