◉ Product Description

C20 seamless steel pipe is a kind of high-quality steel pipe products, it is made of high-quality carbon structural steel materials, with high strength and excellent processing properties. The steel pipe is made of wool tube by perforation process, and then finished by hot rolling, cold rolling or cold drawing processing technology. 20# seamless steel pipe belongs to low carbon steel pipe, carbon steel according to carbon content can be divided into low carbon steel, medium carbon steel and high carbon steel three categories, and 20# seamless steel pipe carbon content is low, widely used in structural tubes, fluid pipes, low and medium pressure boiler tubes and other fields. If there is no special requirement, 20# seamless steel pipe is generally used.
