Conventional Conveyor Chain–Classification by Surface Treatment

You will find several different selection for heat treatment method and specs for your conveyor chains. Certain remedies is usually utilized not simply on the chain being a complete but to each and every element separately, this kind of as pins or plates only.
Choose wanted combinations in reference on the following explanation of capabilities and makes use of.
Double Guard Coating
The surface is treated with exceptional corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating consists of double layers of two distinctive products. It exhibits virtually doubled corrosive resistance in the salt water spray check in contrast to our typical high guard coating, and will be utilized in mild alkaline or mild acidic problems up to pH3.
With its enhanced corrosive resistance, it could be utilized in conditions in which substantial guard or plated coatings cannot be utilised, and even in some disorders the place only stainless steel is often used.
(Double guard coating can’t be applied to welded elements.)
Higher Guard Coating
Higher guard coated surface has excellent corrosion resistance.
The surface on the chain is completed in non-gloss white really protective coating. It has outstanding resistance to salt corrosion and rusting. This coating protects chains in large temperatures since it can resist heat as much as about 250°C.
Because higher guard coating acts being a sacrificial anode for the chain physique, it is possible to anticipate ample corrosion resistance even when the coating has come off to some extent. Also, it can be applied to welded parts.
It is actually encouraged for outside use or near the sea in conditions the place performance as high as that of stainless steel is not vital. In situations that demand resistance to alkaline and acid, double guard or stainless steel coating is advisable as they have improved resistance than substantial guard.
Plating is largely finished with nickel. It is a coating with both attractive exterior and corrosion resistance. Through the use of it with grease lubrication, it exhibits excellent corrosion resistance. You could count on the effect to delay hydrogen brittle destruction when utilized in situations where chains are exposed to sea breeze or acidic sprays.
