There are actually a number of assortment for heat treatment and specifications for the conveyor chains. Certain therapies can be applied not only for the chain being a total but to every element individually, such as pins or plates only.
Choose wanted combinations in reference for the following explanation of features and employs.
Double Guard Coating
The surface is taken care of with exceptional corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating consists of double layers of two unique products. It exhibits nearly doubled corrosive resistance within the salt water spray check in contrast to our conventional substantial guard coating, and will be utilized in mild alkaline or mild acidic circumstances as much as pH3.
With its improved corrosive resistance, it may be used in conditions exactly where high guard or plated coatings can’t be used, as well as in some conditions where only stainless steel is often applied.
(Double guard coating cannot be applied to welded elements.)
High Guard Coating
Large guard coated surface has superb corrosion resistance.
The surface with the chain is finished in non-gloss white extremely 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 that higher guard coating acts as being a sacrificial anode to the chain physique, you may expect sufficient corrosion resistance even if the coating has come off to some extent. Also, it might be utilized to welded parts.
It can be advised for outside use or near the sea in situations wherever effectiveness as substantial as that of stainless steel just isn’t essential. In circumstances that need resistance to alkaline and acid, double guard or stainless steel coating is advised as they have improved resistance than high guard.
Plating
Plating is primarily done with nickel. It is actually a coating with both appealing exterior and corrosion resistance. By using it with grease lubrication, it exhibits excellent corrosion resistance. It is possible to expect the result to delay hydrogen brittle destruction when used in situations where chains are exposed to sea breeze or acidic sprays.
(Double guard coating can’t be applied to welded parts.)
