ASTM A312 TP304L Stainless Steel welded Tube introduce
The TP304L stainless steel welded pipe conforms to the ASTM A312 standard. It is an ultra-low carbon austenitic steel, designed for improved intergranular corrosion resistance in welded components, outperforming standard 304. It is suitable for chemical pipelines and food equipment, meeting the cleanliness requirements for food and pharmaceutical applications.

Advantages of ASTM A312 TP304L electric welded tubing
304 stainless steel welded pipes are 40%-50% cheaper than 316L welded pipes of the same specification. They are particularly suitable for large-scale pipeline projects with medium corrosion intensity in non-strong reducing acid environments (such as hydrochloric acid).
304 stainless steel pipes can be welded using efficient welding methods such as automatic argon arc welding (TIG) and plasma welding. The welds are evenly formed, post-weld grinding processes are reduced, and processing costs are reduced by more than 30%.
