You’ll find various variety for heat treatment method and specs for the conveyor chains. Unique remedies might be utilized not only to your chain being a entire but to just about every part separately, such as pins or plates only.
Decide on desired combinations in reference for the following explanation of characteristics and uses.
Double Guard Coating
The surface is treated with excellent corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating consists of double layers of two distinct materials. It exhibits practically doubled corrosive resistance from the salt water spray test in contrast to our conventional substantial guard coating, and may be utilized in mild alkaline or mild acidic situations up to pH3.
With its improved corrosive resistance, it may be used in situations wherever high guard or plated coatings cannot be utilized, and also in some disorders wherever only stainless steel could be employed.
(Double guard coating cannot be applied to welded components.)
Large Guard Coating
Large guard coated surface has superb corrosion resistance.
The surface of the chain is finished in non-gloss white highly protective coating. It has fantastic resistance to salt corrosion and rusting. This coating protects chains in substantial temperatures as it can resist heat up to about 250°C.
Considering the fact that substantial guard coating acts as a sacrificial anode for the chain body, you could anticipate ample corrosion resistance even if the coating has come off to some extent. Also, it might be applied to welded elements.
It really is suggested for outside use or near the sea in situations where performance as substantial as that of stainless steel is not really required. In situations that call for resistance to alkaline and acid, double guard or stainless steel coating is advised because they have much better resistance than substantial guard.
Plating
Plating is mostly completed with nickel. It is a coating with both interesting exterior and corrosion resistance. By using it with grease lubrication, it exhibits superb corrosion resistance. You may anticipate the impact to delay hydrogen brittle destruction when utilized in situations wherever chains are exposed to sea breeze 
or acidic sprays.
