There are various assortment for heat treatment method and specs for that conveyor chains. Particular treatment options can be utilized not simply for the chain as being a full but to just about every element individually, such as pins or plates only.
Select sought after combinations in reference for the following explanation of capabilities 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 distinct resources. It exhibits nearly doubled corrosive resistance inside the salt water spray test in contrast to our traditional substantial guard coating, and might be used in mild alkaline or mild acidic situations up to pH3.
With its enhanced corrosive resistance, it might be utilized in circumstances the place large guard or plated coatings can’t be made use of, and also in some ailments exactly where only stainless steel may be made use of.
(Double guard coating cannot be applied to welded elements.)
High Guard Coating
Substantial guard coated surface has superb corrosion resistance.
The surface on the chain is finished in non-gloss white hugely protective coating. It’s great resistance to salt corrosion and rusting. This coating protects chains in high temperatures since it can resist heat up to about 250°C.
Due to the fact high guard coating acts as a sacrificial anode for the chain body, it is possible to assume sufficient corrosion resistance even when the coating has come off to some extent. Also, it could be utilized to welded components.
It’s suggested for outside use or close to the sea in situations in which overall performance as substantial as that of stainless steel will not be important. In conditions that call for resistance to alkaline and acid, double guard or stainless steel coating is advisable because they have improved resistance than high guard.
Plating
Plating is generally performed with nickel. It is actually a coating with the two interesting exterior and corrosion resistance. Through the use of it with grease lubrication, it exhibits superb corrosion resistance. You may anticipate the effect to delay hydrogen brittle destruction when utilized in conditions where chains are exposed to sea breeze or acidic sprays.
