ASTM A48 covers a class of cast irons that are intended for general use applications. Grades of ASTM A48 Grey Iron Produced at Matrix Iron Foundry What is Hardness of Gray Cast Iron - Definition Material Hardness of Gray Cast Iron ASTM A48 Class 40. Brinell hardness of gray cast iron (ASTM A48 Class 40) is approximately 235 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.
For example, ASTM A48 Class 20 will be detailed enough for iron foundries, it means the min. tensile strength of gray iron castings must be higher than 20 ksi ( Mpa). ASTM A48 Class 20:Min. Tensile Strength 20 ksi ( Mpa) ASTM A48 Class 25:Min. Tensile Strength 25 ksi (172 Mpa) ASTM A48 Class 30:Min. Tensile Strength 30 ksi (207 Mpa)
