C70 Steel

Product Description:

C70 steel is a high-carbon steel with a carbon content of approximately 0.70%, known for its excellent hardness, wear resistance, and strength. This steel is primarily used in applications where high wear resistance and hardness are required, such as in the production of cutting tools, springs, and high-stress mechanical components. C70 is a non-alloy steel, which means it does not contain significant amounts of other alloying elements, but it can be heat-treated to enhance its properties.
