Passive layer: • Cr > 12%, Nickel, Molybden, Mangan, Titan. • Thin protective layer of chromium oxide - the passive layer. • Repairs itself - if it is not exposed to contamination or
damage.

Facts about stainless steel
Heat treatment Thermal Effects destroys the chromium content in the stainless steel. Base Metal; - consist of Cr = 18% The surface gets a layer that needs to be removed. The layer consists off: Outer;- Welding oxide Cr > 10% Under;- 2-8 µm crom –poor zoon Cr < 10%
Production – What problems occur?
Treatment with TermoRens is an effective method for pacification of stainless material. Cleansing method GEL: Apply with a brush, roller or sprayed on. Clean using a 200 bar high pressure washer with steam. Cleansing method for liquid: Use dipp-tray with 50% diluted ThermoRens liquid. Treatment period from 12 hours to one day depending on the degree of corrosion. Clean with 200 bar high pressure washer with steam.
Pacification of stainless material after production, grinding, welding, forming.
