Steel pipe network provides: 20# seamless steel pipe implementation standards
20 # seamless steel pipe material is 20 # steel, the strength is slightly higher than the 15th steel, rarely quenching, no temper brittleness. Cold deformation high plasticity, general for bending, rolling, crimping and hammer arch processing, arc welding and contact welding welding performance, gas welding thickness is small, strict shape or complex shape of the parts are prone to cracking. Machinability Cold drawing or normalizing is better than annealing. It is generally used for manufacturing with low stress and high toughness requirements.
The material of 20# seamless steel tube is: High-quality carbon structural steel Grade: 20 Steel Standard: GB8162-2008 (structure tube) GB/T8163-2008 (fluid tube) GB3087-2008 (low and medium pressure boiler tube) GB5310-2008 ( High pressure boiler tube
The strength is slightly higher than that of No. 15 steel, rarely quenched, and has no temper brittleness. Cold deformation high plasticity, general for bending, rolling, crimping and hammer arch processing, arc welding and contact welding welding performance, gas welding thickness is small, strict shape or complex shape of the parts are prone to cracking. Machinability Cold drawing or normalizing is better than annealing. It is generally used for manufacturing with low stress and high toughness requirements.
