Firstly, the thicker the wall thickness of 20Cr seamless steel pipe is, the more economical and practical it is. The thinner the wall thickness is, the higher the processing cost will be;
Secondly, the process of 20Cr seamless steel pipe determines its limited performance. Generally, the precision of the seamless steel tube is low: the wall thickness is uneven, the brightness of the inner and outer surface of the tube is low, the sizing cost is high, and there are pockmarks and black spots on the inner and outer surface that are not easy to remove;
Third, the detection and shaping of 20Cr seamless steel pipe must be handled offline. Therefore, 20Cr seamless steel pipe shows its advantages in high pressure, high strength and mechanical structure materials.
