SVHS

May be used with vacuum chamber applications in clean rooms, FPD (Flat Panel Display) and semiconductor production equipment and devices.
All Clean washed. Clean-Wash format prevents inclusion of oil and foreign particles.
The SVHS-PC PC Chemical Polish improves surface roughness and reduces diffusion to microscopic levels.
Material/Finish
SUSXM7 (SUS304 Equivalent)
SVHS : Without Surface Treatment
SVHS-PC : Chemical Polish
We manufacture specialty-use product dimensions, profiles, materials, surface treatments, and special packaging.
