Implementation Standards
GB/T3639、DIN2391、EN10305-4、DIN2393、ASTM A519
Applicable Scope
Automobile, machinery fittings, etc., have high requirement for the precision and smoothness of the steel pipe. Precision steel users are not only relatively high accuracy and smoothness requirements of the user, because the precision bright tube of high precision, tolerance can be maintained in the 2--8 wire, so many users in order to save the loss of mechanical processing industry, material, the seamless steel pipe or steel will slowly change as precision bright tube.
