Application
Antireflection. Optical instruments, FPD production equipment,semiconductor devices, vacuum applications,
and general industrial machines
Characteristics
- The stainless black surface treatment develops a passive membrane on the stainless steel surface up to 200 times of normal to produce a deep black finish.
- Excellent corrosion resistance. 8 times more resistant compared to SUS316L and 32 times to SUS304, respectively.
- The membrane contains no impurities and has extremely low outgas even in vacuum environments.
- Spectral reflectance is 1.5% or less. For optical instruments and other applications that require antireflection.⇒The Features of Screws with Special Surface Treatment
- Deep black color decorates surfaces of equipment and devices.
- Conforms to JIS B 1176, ISO 4762, and DIN 912.
