Properties and applications |
| SUS304 |
General-purpose stainless steel: Used to make general chemical equipment, food equipment and nuclear power equipment, and in construction and household supplies. |
| SUS304L |
304 ultra-low carbon steel: More resistant to intergranular corrosion than 304. Used when heat-treatment after welding is not possible. |
| SUS316 |
Stainless steel made by adding molybdenum to 304 for improved corrosion resistance. Used in items such as ship parts. |
| SUS316L |
316 ultra-low carbon steel: Has higher intergranular corrosion resistance. Used in areas requiring resistance to corrosion and pitting. |
| SUS317 |
Higher corrosion resistance than 316. Used to make equipment for applications such as papermaking and dyeing. |
| SUS317L |
317 ultra-low carbon steel: Has higher intergranular corrosion resistance than 317. |
| SUS309S |
Has higher corrosion resistance than 304. Used mainly as a heat-resistant steel. |
| SUS310S |
Has higher oxidation resistance than 309. Used mainly as a heat-resistant steel. |
| SUS321 |
Made by adding titanium to 304 to increase intergranular corrosion resistance. |
| ニッケル合金 |
Has very high oxidation and heat resistance. Used in corrosive and high-temperature environments. |
