technical data Before using Top chain
Corrosion resistance to various liquids
When selecting a chain, check the table below to see if the material is sufficient. This corrosion resistance can also be used to check the rail material to be used with Top chain.
Please note that this table shows the results in an atmosphere of 20°C and does not represent the degree of guarantee. When actually using the product, please comprehensively consider the temperature, operating conditions, etc. 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% solutions. Please note that the conditions will change if you mix solutions.

Note)
- "○": Sufficient corrosion resistance, "△": Corrosion resistance exists depending on the conditions of use, "×": No corrosion resistance, "-": Unknown.
- Please check two things: the chain body material and the pin material.
- Applicable: Standard Series, Low Friction / Anti-Wear (CB) specifications, ultra-Low Friction / Anti-Wear (ALF) specifications, low friction (WR) specifications, conductive (E) specifications, ultraviolet resistant (UVR) specifications.
- Applicable to: Low Friction / Anti-Wear (LFW, LFG, LFB) specifications, low friction (NLF) specifications, Low Friction / Anti-Wear (HG) specifications, antibacterial and antifungal (MWS) specifications.
- Target: Heat-resistant and high-speed (KV) specifications also take into consideration the corrosion resistance of stainless steel pin types.
- The chemical resistant (Y) specification also takes into consideration the corrosion resistance of the stainless steel pin type.
- Do not use the heat-resistant/high-speed (KV150) specification, high-speed (HS) specification, impact-resistant (DIA) specification, metal detection (MPD) specification, or medium friction (MF) specification in conditions where they may come into contact with liquids such as detergents or chemicals. Please contact us if you have any requests or questions.
- Please contact us for information on corrosion resistance of metal detection (MPW) specifications.
- Do not clean the chain with anything other than water.
- Do not clean the chain with detergents, organic solvents, acids, alkalis, etc. Also, do not use the chain in places where it may come into contact with such chemicals.
Chemical cracks may occur and cause the chain to break.
