- 1. SUS304(JIS G4314 WPB) level of strength as well as spring characteristics.
- 2. Heat resistance deterioration characteristics are on par with those of NAS316H1 and approach those of SUS631J1.
- 3. Corrosion resistance greatly exceeds that of SUS316 as well as NAS316H1.
- 4. Through limiting use of high-priced nickel and molybdenum, great cost reductions are possible.
