Use in Acidic or Alkaline Conditions Exposure to acids will increase chain wear. Brittleness and breakage may occur when standard mechanical abrasion is compounded by chemical corrosion. Acids are more damaging to chain than alkali. Electrochemical corrosion caused by seawater or pit water may also occur. In these cases, chain should be plated or manufactured with corrosion resistant materials. Use in Abrasive Conditions Abrasion occurs when sand, coke, metal particles, or dust in the air becomes embedded in the moving or engaging parts of the chain and sprocket. Take the following steps when operating under these conditions: 1. Reduce bearing pressure by using a larger chain size. 2. Increase wear resistance by applying special processing to the parts of the chain where abrasion is a problem.
