Technical Data  Top chain  Before Use

Corrosion resistance to various liquids

When selecting a chain, check from the table below that its material is adequate. This corrosion resistance can also be used to check the rail material used with the top chain.

Note that the results in this table are based on a 20°C atmosphere and do not represent the degree of guarantee. Comprehensively consider the temperature/usage conditions, etc. in actual use. The table below lists the materials (specifications) of the top plate and chain components individually, so please check them in combination.

Reagents without a concentration indication are saturated or 100% solution. Note that conditions will change when solutions are mixed together.

Note)

  1. ○: Totally resistant, △: Partially resistant (depending on operating conditions, ×: Not resistant, -: No data
  2. Please check two things: the chain base material and the pin material.
  3. “Standard polyacetal” includes Standard, CB, ALF, WR, E, UVR.
  4. Applicable to: Low friction/Wear resistant (LFW, LFG, LFB) , Low friction (NLF), Low friction/Wear resistant (HG), Antibacterial/Mold resistant (MWS) series.
  5. Applicable to: Heat resistant/High speed (KV) series also consider corrosion resistance of stainless steel pin type.
  6. Chemical-resistant (Y) series also takes into account the corrosion resistance of stainless steel pin types.
  7. Do not use the heat-resistant/High-speed (KV150), High-speed (HS), Impact-resistant (DIA), Metal detectable (MPD), and Middle-friction (MF) series under conditions where they will be subjected to liquids such as detergents or chemicals. If you have any requests or questions, please contact us.
  8. For corrosion resistance of Metal detectable (MPW) series, please contact us.
  9. Do not wash the chain except with water.
  10. Do not clean the chain with detergents, organic solvents, acids or alkalis. Do not use the product in areas where it will come in contact with such chemicals.
    Chemical cracks may occur and the chain may break.
