Iron Ore Crush Hardness
Steel vs Iron
Hardness of Steel vs Iron. Brinell hardness of low-carbon steel is approximately 120 MPa. Brinell hardness of high-carbon steel is approximately 200 MPa. Brinell hardness of gray cast iron (ASTM A48 Class 40) is approximately 235 MPa. Brinell hardness of gray cast iron martensitic white cast iron (ASTM A532 Class 1 Type A) is approximately 600 MPa.
