Cast Iron Brinell Hardness, Ductile Iron and Gray Cast Iron

Brinell hardness is a typical hardness specification for cast iron products, especially for ductile iron and gray cast iron. However, in the most international standards, cast iron hardness is not a necessary inspection specification.

In most instances the chemical composition is not specified; rather it is the tensile strength and Brinell hardness which are written into specifications for certain applications. For example, automotive disk brake rotors and brake drums are produced from a class 30 Gy iron with a Brinell hardness range of 179–229 kg mm −2. It is usually

Reasonable machining hardness range for iron and steel

According to my experience in the iron foundry in China, the following hardness range is suitable. 1. The reasonable hardness range to cast iron Normally, the hardness of cast iron is indicated by BH (Brinell Hardness) or HB (Hardness of Brinell). The hardness less than HB 220 will be suitable for normal machining process.
