Explanation
steel with carbon content in the range of 0.25% -0.6%. In the narrow sense, low-cardon steel refers to non-alloy steel with carbon content in the range of 0.25% -0.6%. hot working and cutting properties are good. weld parts have poor strength, higher hardness than low-carbon steel, and slightly lower plasticity and toughness than low-carbon steel. It can be directly used in rolling state or cold drawing state to make engineering parts or components with medium strength. After quenching and tempering and heat treatment, it has good comprehensive mechanical properties and is widely used to make bolt shaft mechanical parts.
