ASTM-A524Standard Specification For Seamless Carbon Steel Pipe For Atmospheric And Lower Temperatures For Auto Parts
The steel pipe conforms to the American ASTM-A524 standard. It is made of carbon steel pipe billet and produced by
European technology. It can effectively control the dimensional tolerance of small-diameter thick-walled steel pipe.
The inner and outer diameter tolerance can be controlled within 0.05mm, and the wall thickness tolerance can be
controlled within 0.07mm. Parts with high precision and requirements, auto parts, etc.
