When exporting stainless steel seamless pipes, what is the difference between “TP304” and “304” often asked by customers?

Answer: In the ASTM standard, “TP” stands for “Tube/Pipe”. TP304 refers to 304 material stainless steel pipes that meet the ASTM standard. In practical applications, the material composition of the two is basically the same, but TP304 emphasizes its standardization as a pipe material.
