20# /45 # /50# /S45C Carbon steel Plate

20# /45 # /50#  /S45C Carbon steel Plate：

45 # carbon plate, commonly known as 45 # steel in China, represents the chemical composition of the steel (with a carbon content of about 0.45%).

 Hot rolling is mostly available in the general market spot.

 Cold rolling specifications between 1.0 and 4.0mm.

 45 # steel is a high-quality carbon structural steel, belonging to medium carbon steel, which can be quenched. After heat treatment, its strength and hardness are high, making it suitable for making mechanical parts and used in situations that require high stress and good wear resistance.

 Therefore, it belongs to mechanical steel and is mainly used as mechanical parts, such as shafts, gears, high-strength bolts, etc.
