Stainless Steel Compatibility
MATERIAL OF COMPONENT PARTS
STAINLESS STEEL CHAIN SELECTION
General selection is based on bearing pressure between the pin and bushing. Anti-corrosive roller chains are normally intended to be used at slow speeds without lubrication. Chain selection should be made based on the bearing pressure shown below.

Corrosion Resistance Good for general acid, alkali and water
Temperature Resistance -40 ºF to 750ºF (Never use below -270ºF or over 1300ºF) -40 ºF to 750ºF (Never use below -420ºF or over 1500ºF) -40 ºF to 750ºF (Never use below -40ºF or over 930ºF)
Wear Resistance
Maximum allowable load or maximum bearing pressure as shown above can be doubled only when chain is used in group 1 of the “Corrosion Resistance Guide” and properly lubricated. Vibrations arising from ultrasonic waves, etc., must also be taken into consideration.
Magnetism
304 (SS)
Slightly magnetic due to cold forming of parts
Fair
316 (NS)
Superior to SS and AS
Non-magnetic
Fair
600 (AS)
Slightly less than above
