1.This steel pipe has been cold drawn. The steel pipe that has been cold-treated has high precision and good surface finish. In addition, cold-drawn steel can produce seamless steel tubes of smaller size and better quality;
2.The inner and outer surface of the cold-rolled steel pipe has good surface finish, roundness and straightness, which can improve the processing efficiency and material utilization rate;
3.The steel pipe is 309 stainless steel pipe. 309 stainless steel can withstand repeated heating, with high temperature strength and oxidation resistance, carburization resistance.
