304 vs TP304 Difference between 304 and TP304 in China
TP304 is equivalent to 06Cr19Ni10 (new GB standard 304), 304 is equivalent to 0Cr18Ni9(old GB standard 304).
In terms of price, TP304 is also about USD 65 more expensive than 304 (per metric tons)
What is the element content?
The main difference between 304 and TP304 is its chromium content. The chromium content of TP304 is one higher, reaching more than 18, so its corrosion resistance and price are slightly higher than that of GB 304. Therefore, TP304 is more expensive than 304 in price, and the ingredients are as follows:
| Grade | – | C | Mn | Si | P | S | Cr | Mo | Ni | N |
| TP304 | min.max. | -0.08 | -2.0 | -1.00 | -0.045 | -0.030 | 18.0-20.0 | – | 8.0-11.0 | – |
| 304 | min.max. | -0.08 | -2.0 | -1.00 | -0.040 | -0.015 | 17.00-19.5 | – | 8.0-10.5 | – |
