Cold rolled high carbon steel C75 coil refers to a specific type of steel coil made of C75 high carbon steel through a cold rolling process. C75 is a high carbon steel, typically containing about 0.75% carbon. High carbon steel provides hardness, wear resistance and is suitable for applications where sharp edges and high strength are required.
C75 is a standard Euronorm high carbon spring steel, part of EN10132. It has a carbon content of 0.7-0.8% making it a multi-purpose carbon steel with good spring properties. Therefore, it is a commonly used carbon steel in a wide range of engineering applications. C75 steel hardness range is 400/450 vpn.

C75 carbon spring steel is a high-carbon steel alloy known for its strength, toughness, and durability. It contains 0.7-0.8% carbon, 0.15-0.35% silicon, 0.6-0.9% manganese, and 0.03% phosphorus and sulphur. It has a tensile strength of 1230-1340 MPa, yield strength of 1130-1240 MPa, and a hardness of 57-63 HRC. It can be heat treated to achieve the desired properties and hardened by quenching and tempering.
