TP304 is an expression of 304 American Standard, and TP is short for tube & pipe. In terms of difference, the main reason is that the chemical composition is somewhat different from the selling price, and other data are basically the same.
304 refers to the national standard, the old brand is Cr18Ni9 0, and now the new brand is Cr19Ni10 06, which everyone should know. In the composition of stainless steel, we are more concerned about the content of Cr, Ni, C these three elements.
304:C≤0.08,Ni:8.00-11.00,Cr:17.00-19.00;
TP304:C≤0.08,Ni:8.00-11.00,Cr:18.00-20.00;
The main difference between TP304 and 304 is that the content of Cr is different. TP304 has one more chromium than 304, so TP304 is more expensive than 304.
