1、 Low carbon steel

Low carbon steel refers to steel with a carbon content less than 0.25%. Due to its low carbon content, it has good plasticity, toughness, and weldability, but low strength and hardness. Widely used in the manufacturing of mechanical parts such as machine parts, axles, bolts, nuts, etc.

2、 Medium carbon steel

The carbon content of medium carbon steel ranges from 0.25% to 0.6%. Medium carbon steel has higher hardness and strength, but reduced plasticity and toughness. Suitable for manufacturing various gears, bearings, cycloids, etc.

3、 High carbon steel

The carbon content of high carbon steel ranges from 0.6% to 1.5%, making it the steel with the highest carbon content. It has high wear resistance, hardness, and elasticity, but low toughness and is prone to fracture. Widely used in the manufacturing of high-strength and high hardness parts such as hammers, stamping molds, and saw blades.

In summary, the differences between low-carbon steel, medium carbon steel, and high carbon steel mainly lie in their carbon content and mechanical properties. According to different application requirements, corresponding steel can be selected to make parts for optimal use.
