There are a number of choice for heat treatment method and specifications for the conveyor chains. Certain treatment options might be applied not simply to the chain as a total but to each and every element individually, such 
as pins or plates only.
Choose wanted combinations in reference on the following explanation of functions and makes use of.
Double Guard Coating
The surface is treated with outstanding corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating includes double layers of two unique materials. It exhibits practically doubled corrosive resistance during the salt water spray check compared to our standard substantial guard coating, and may be utilized in mild alkaline or mild acidic situations as much as pH3.
With its improved corrosive resistance, it may possibly be utilized in conditions wherever substantial guard or plated coatings cannot be employed, and in some cases in some disorders wherever only stainless steel can be utilised.
(Double guard coating cannot be utilized to welded parts.)
Large Guard Coating
Substantial guard coated surface has superb corrosion resistance.
The surface from the chain is finished in non-gloss white remarkably protective coating. It’s exceptional resistance to salt corrosion and rusting. This coating protects chains in large temperatures since it can resist heat up to about 250°C.
Considering that large guard coating acts being a sacrificial anode for your chain physique, you may count on enough corrosion resistance even when the coating has come off to some extent. Also, it may possibly be utilized to welded parts.
It is encouraged for outdoor use or close to the sea in conditions in which functionality as substantial as that of stainless steel is just not needed. In situations that need resistance to alkaline and acid, double guard or stainless steel coating is proposed as they have far better resistance than substantial guard.
Plating
Plating is mainly finished with nickel. It’s a coating with the two interesting exterior and corrosion resistance. Through the use of it with grease lubrication, it exhibits exceptional corrosion resistance. It is possible to assume the result to delay hydrogen brittle destruction when used in conditions where chains are exposed to sea breeze or acidic sprays.
(Double guard coating cannot be applied to welded components.)
