What is the hardest that GREY cast iron can be?

gray irons are equally strong, or equally hard. As in steel, tensile strength and hardness are closely related. In gray irons, tensile strength ranges from about 14 MPa (20,000 psi) to more than 35 MPa (50,000 psi). The hardness of the strongest grades is double that of the weakest grades.

Where would cast iron be used on a car?

With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts, such as cylinder heads, cylinder …

What is the hardness of Brinell gray iron?

Brinell hardness of Gray 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.

What is the hardness range of ductile iron?

The following list is for the typical Brinell Hardness range for the main grades of ductile iron and grey cast iron. Resonable Brinell Hardness Range of Ductile iron castings:

What is the maximum tensile strength of gray iron?

Ultimate Tensile Strength Ultimate tensile strength of Gray Iron (ASTM A48 Class 40) is 295 MPa. The ultimate tensile strength is the maximum on the engineering stress-strain curve. This corresponds to the maximum stress that can be sustained by a structure in tension.

Why is the hardness of cast iron important?

If the hardness is very important for your products, for example, you need the better abrasive resistance, then you should add one hardness requirement for your products, so the casting manufacturers could adjust the chemical composition to increase its hardness.
