Classification and difference of 304 stainless steel pipe

Classification and difference of 304 stainless steel pipe 2018-09-30 304 stainless steel will have 304H and 304L according to the material. Recently, I also saw a TP304. What is the difference or difference between them? According to the requirements for the content of chromium and nickel in 304 stainless steel, it belongs to the category of 304 stainless steel, and the difference between 304H and 304L in 304 stainless steel is mainly the difference of carbon content. Usually we say that the content of 304 means that the carbon content is less than or equal to 0.08, while the carbon content of 304L series stainless steel is less than or equal to 0.03, and the 304H series stainless steel is a kind of higher carbon content. The carbon content of 304 stainless steel is between 304L and 304H. The content of phosphorus and sulfur in TP304 is different from that of 304 stainless steel, and the content of chromium is slightly higher than that of 304 stainless steel. The sulfur content of TB304 is between 0.001 and 0.003, and it is mostly used for pipe threading. The above is the classification of the stainless steel editor. If you have a better point of view, please share it.
