Information

 

What are the advantages of each? The materials of 10# and 20# seamless steel tubes are different and the hardness is different. 10 and 20 represent the level of their carbon content. In GB9948, the carbon content of 10# is 0.07-0.14, and the carbon content of 20# C is 0.17-0.24. If there are no special requirements for seamless steel tubes, 20# seamless steel pipes are used. 

 

 

The higher the content of C, the higher its hardness and strength, but the lower the toughness and plasticity, the worse the weldability. 10# Hardness is not enough, but the toughness is very good. It is reliable in welding and is not prone to cracking. It is suitable for small diameter pipes, such as oil pipes on automobiles. 20# Hardness is moderate, toughness is also ok, so it is the most widely used, pipe, pipe fittings, machining equipment, etc. can be used.
