ATSM 312 Stainless Steel Seamless Pipe TP304 Use in Petroleum Refineries
Product Discription:
Stainless Steel 304 Pipe is a metallic pipe made up of an austenitic stainless steel that has 18% chromium and 8% nickel in the composition. Zheheng Steel is a leading supplier and manufacturer of the Stainless Steel 304 Pipe in different types and sizes. The specifications for the pipes range as A312 and A358 in the ASTM specifications. The dimensions range according to the ASTM, ASME and API standards. There are welded and SS 304 Pipe as well as electric fusion welded pipes.
The characteristics of 304:
- Weak magnetic, after stretching/stamping and other cold processing will be stronger magnetic
- Corrosion resistance (not completely resistant to corrosion), good toughness
Use of TP304 stainless steel:
It is widely used in high-temperature and electric industry, medical devices, construction, chemistry, food industry, agriculture, and ship components.
The components of 304 are as follows:
| Grade | C | Mn | Si | P | S | Cr | Mo | Ni | N |
