What is Hardness of Ductile Cast Iron - Definition
Brinell hardness of ductile cast iron – ASTM A536 – 60-40-18 is approximately 150 – 180 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching. Ductile iron is stronger and more shock resistant than gray iron.sp.info Mechanical Properties of Gray Iron - HardnessTable 3. Hardness Ranges for Gray Irons . Type of Gray Iron .
