Typical Applications |
| TP304/304L |
S30400/S30403 |
It is widely used in the food and beverage, chemical, and pharmaceutical industries. It is ideal for making equipment, tanks, and pipelines where high corrosion resistance and cleanliness are essential. |
| TP316/316L |
S31600/S31603 |
It is commonly used in marine environments, chemical processing, and medical equipment due to its enhanced pitting and crevice corrosion resistance. |
| TP317 |
S31700 |
It is suitable for use in highly corrosive environments, such as chemical processing, pulp and paper production, and food processing industries. |
| TP321 |
S32100 |
Primarily used in high-temperature environments such as aerospace, chemical processing, and petroleum refining industries. The addition of titanium provides resistance to intergranular corrosion. |
| TP347 |
S34700 |
Used in high-temperature applications like power generation, oil and gas, and chemical processing industries due to its resistance to intergranular corrosion. |
| TP348 |
S34800 |
Similar to TP347 but with a slightly different chemical composition, it is used in nuclear and aerospace applications. |
| S31254 |
S31254 |
It is known for its high pitting and crevice corrosion resistance, making it suitable for seawater and aggressive chloride-bearing environments. It is commonly used in desalination plants, chemical processing, and marine applications. |
| S30600 |
S30600 |
It is often used in applications requiring high strength and moderate corrosion resistance, such as in the chemical processing and oil and gas industries. |
| S32654 |
S32654 |
Excellent resistance to pitting, crevice, and stress corrosion cracking. Typically used in seawater handling systems, oil and gas exploration, and chemical processing. |
| N08904 |
N08904 |
Highly resistant to corrosion in both reducing and oxidizing environments. Commonly used in chemical processing, pollution control equipment, and pulp and paper production. |
