Material/Finish
| SNSX-88 | |
|---|---|
| Main Body | SUS316L HiMo |
| Strength Class | 8.8 |
Application
FPD production equipment, semiconductor devices, sputteringequipment, aquatic applications, and general industrial machines
Characteristics
- High intensity socket head cap screws are made of stainless steel. (Strength Class 8.8 or 10.9)
- For applications that require both high strength and corrosion resistance.
- High strength per a screw is useful for space and weight saving by decreasing thread diameter and number.
- Screws with excellent heat resistance and corrosion resistance.
- Nonmagnetic.
- Conforms to JIS B 1176, ISO 4762, and DIN 912.

Result of corrosion test by metal materials
SUS316L HiMo steel used in SNSX is a special steel alloy with reduced carbon and increased Cr, Ni, and Mo. Reducing carbon shows an increased resistance to grain boundary corrosion cracking, and adding Cr and Mo increases resistance to pitting corrosion and crevice corrosion. In addition, adding Ni effectively reduces the risk of stress corrosion cracking.The chart below shows the degree of corrosion after 10 years of exposure to conditions similar to seawater environment, and there was no corrosion for CR3 or lower.
