1045 Cold Rolled Steel Coil

1045 Cold Rolled Steel Coil is a medium-carbon, cold-reduced steel product that offers a superior surface finish and precise dimensional tolerances. It is characterized by higher strength and hardness compared to mild steels, along with good machinability. The material conforms to AISI/SAE 1045 standard, known for its balanced carbon content. This coil is primarily used for manufacturing parts that require greater strength and wear resistance, such as gears, shafts, and machinery components.
