GB/T 5310 20MnG boiler pipe is belong to Chinses standard, and Katalor is a famous steel supplier and exporter in China. We can suppliy GB/T 5310 20MnG boiler pipe with high quality and best service. But GB/T 5310 20MnG boiler pipe is low carbon steel, which is prone to hot deformation cracks. Katalor will give you some measures to solve this problem.
Component control: For GB/T 5310 20MnG boiler pipe, the carbon is removed at the highest limit, the peritectic reaction is avoided, the acid soluble aluminum is the lowest and the nitrogen is the lowest. The high temperature plasticity of the steel can be raised by the Ti.
Continuous casting: Select the type of crystal selector in GB/T 5310 20MnG boiler pipe, the viscosity of mold powder. To increase the vibrational frequency rate of the crystal junction and / or the force degree of the less shock motion to reduce the recovery time; second cold water: choose soft or hard cold straightening Brittleness should be straightened at higher or lower temperatures.
Rolling: By slowing down the reheating rate of GB/T 5310 20MnG boiler pipe billet in the soaking furnace, the probability of the appearance of stripe crack can be obviously reduced.
We have the professional person and team to produce the good quality GB/T 5310 20MnG boiler pipe. So you can contact us freely if you have any need in GB/T 5310 20MnG boiler pipe. We have different sizes GB/T 5310 20MnG boiler pipe to meet your any requirements.
