< B: < _ The middle refers to boiling steel
Refers to the carbon content of eight ten thousandths
Characteristics:
Low strength and hardness, good plasticity and toughness, easy to deep draw Draw bending and welding.
Usage:
Steel plates are used as deep stamping and deep drawing containers, such as enamel products, dashboards, car cab covers, etc. Round steel is used as carburized or cyanide parts that do not require high core strength. []

< B: < _ The plasticity of steel is very good, Mainly used to manufacture cold stamping parts, which are easy to be rolled into thin plates, cold deformed profiles, and cold drawn steel wires. Used for stamping parts, calenders, various types of cover parts that do not bear load, carburizing and nitriding, and making various sleeves. Mold bracket.

< B : < _ Steel is extremely soft low carbon steel with strength and hardness It is very low, but has extremely high plastic toughness, good cold deformation and weldability, acceptable machinability after normalizing, high magnetic permeability and less residual magnetism after annealing, but extremely low hardenability and hardenability.
It means boiling steel, and the carbon content is 80,000. This steel is a high-quality boiling steel with similar properties to steel, but its aging and sensitivity are better than steel.
Steel is easily rolled into thin plates and strips, cold deformed profiles, cold drawn and stamped welded parts, and surface hardened.
