Common Conveyor Chain–Classification by Surface Treatment

There are actually many different variety for heat treatment method and specifications for that conveyor chains. Distinct treatment options could be applied not just towards the chain as a entire but to every single component separately, such as pins or plates only.
Choose preferred combinations in reference towards the following explanation of capabilities and utilizes.
Double Guard Coating
The surface is taken care of with excellent corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating includes double layers of two various elements. It exhibits practically doubled corrosive resistance inside the salt water spray check in contrast to our standard higher guard coating, and can be utilized in mild alkaline or mild acidic problems as much as pH3.
With its improved corrosive resistance, it may be used in situations where high guard or plated coatings can’t be utilised, and also in some situations the place only stainless steel might be used.
(Double guard coating cannot be utilized to welded parts.)
High Guard Coating
High guard coated surface has excellent corrosion resistance.
The surface on the chain is completed in non-gloss white highly protective coating. It has outstanding resistance to salt corrosion and rusting. This coating protects chains in higher temperatures since it can resist heat up to about 250°C.
Considering that substantial guard coating acts as being a sacrificial anode for the chain entire body, it is possible to count on enough corrosion resistance even if the coating has come off to some extent. Also, it could possibly be utilized to welded components.
It truly is recommended for outdoor use or near the sea in situations the place functionality as large as that of stainless steel is not required. In circumstances that call for resistance to alkaline and acid, double guard or stainless steel coating is advisable because they have better resistance than large guard.
Plating is generally finished with nickel. It is a coating with each interesting exterior and corrosion resistance. By utilizing it with grease lubrication, it exhibits superb corrosion resistance. You may expect the effect to delay hydrogen brittle destruction when utilized in situations the place chains are exposed to sea breeze or acidic sprays.
