The difference between GB5310 seamless steel pipe and seamless steel pipe: 1. The obvious difference from seamless steel pipe is that it has high dimensional accuracy, which can reach 0.05mm. 2. The inner and outer diameter surfaces of precision steel pipes have a high surface finish, and customers can use them directly without processing; while ordinary seamless steel pipes require customers to lathe and polish. GB6479 seamless steel pipe is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, are used seamless pipes. The chemical composition of precision seamless steel pipe includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
