Stainless steel oxide passive film treatment GEP/GEP-W

basic information

- Shut out the generation of particles The contact surface is extremely smooth due to mechanical polishing, electro-polishing, and oxidation film treatment, and there is no generation of fine particles like porous PTFE. - Extremely low level of metal ion elution due to dense oxidation film [GEP] The iron oxidation film suppresses the elution of metal ions into supersaturated ozone water, hydrogen peroxide water, and IPA (isopropyl alcohol), which have a high dissolved oxygen content. [GEP-W] The chromium oxidation film suppresses the elution of metal ions into ultra-pure water, warm pure water, and organic amine-based resist stripping solutions. - Ensuring reliability and safety even under high temperature and high pressure conditions With mechanical strength and heat resistance comparable to general stainless steel products, reliability and safety are ensured even under harsh conditions such as high temperature and high pressure. - Applications in vacuum environments With superior elution resistance due to smoothness beyond electro-polishing, it is suitable for vacuum chambers. Excellent cleanability prevents particle adhesion. [Applicable products for GEP (Gold EP) and GEP-W (Gold EP White)] - Containers (parts of cleaning devices, pure water tanks, filter housings, etc.) - Piping and fittings - Valves - Pumps - Heat exchangers - Vacuum chambers - Other stainless steel products
