Explanation
For steel with carbon content greater than 0.6%, the common carbon content is 0.6% -1.2%. In the narrow sense, low-cardon steel refers to non-alloy steel with a carbon content of more than 0.6%. High carbon steel belongs to high-quality steel or special steel. Generally, it must be used after different forms of heat treatment. Because of the high carbon content, high strength, high hardness, excellent wear resistance and certain plasticity and toughness can be obtained after heat treatment. high-carbon steel is widely used to make tools, molds, springs and other mechanical parts.
