Steel pipe network for: use of 16 manganese steel pipe (16Mn steel pipe)

The purpose of the 16-manganese steel pipe (16Mn steel pipe): The special steel used for the bridge is “Q345B”, the special steel for the car girder is “Q345B”, and the special steel for the pressure vessel is “Q345B”. This kind of steel is to improve the mechanical properties of steel by adjusting the amount of carbon (C). Therefore, according to the level of carbon content, such steels can be further divided into: Low-carbon steels - carbon content is generally less than 0.25%, such as 10, 20 steel, etc.; Medium carbon steel - carbon content is generally between 0.25 ~ 0.60%, such as 35, 45 steel, etc.; high carbon steel - carbon content is generally greater than 0.60%. This type of steel is generally not used to make steel pipes.
The use of 16 manganese steel pipe (16Mn steel pipe); 1, seam pipe for fluid use: GB8163-99 2, seamless steel pipe for boiler: GB3087-1999 3, high-pressure boiler seamless pipe: GB5310-95 (ST45.8-iii type ) 4. High-pressure seamless steel pipe for chemical fertilizer equipment: GB6479-1999 5. Seamless steel pipe for geological drilling: YB235-70 6. Seamless steel pipe for oil drilling: YB528-65 7. Seamless steel pipe for oil cracking: GB9948-88 8. Seamless pipe for petroleum drilling boring: YB691-70 9. Seamless steel pipe for automobile half shaft: GB3088-1999 10. Seamless steel pipe for ship: GB5312-1999 11. Cold drawn precision seamless steel pipe for cold drawing: GB3639- 1999. Various alloy pipes 16Mn, 27SiMn, 15CrMo, 35CrMo, 12CrMov, 20G, 40Cr, 12Cr1MoV, 15CrMo steel pipes are divided into two types of seamless steel pipes and welded steel pipes according to different production processes.
