Standard Conveyor Chain–Classification by Surface Treatment method

You’ll find a number of assortment for heat treatment method and specs for that conveyor chains. Specific treatments is usually utilized not simply on the chain like a full but to every element individually, such as pins or plates only.
Choose preferred combinations in reference on the following explanation of capabilities and employs.
Double Guard Coating
The surface is handled with outstanding corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating consists of double layers of two various products. It exhibits virtually doubled corrosive resistance from the salt water spray test in contrast to our traditional substantial guard coating, and will be utilized in mild alkaline or mild acidic ailments up to pH3.
With its improved corrosive resistance, it may possibly be used in circumstances the place high guard or plated coatings can’t be utilized, and also in some conditions in which only stainless steel is often applied.
(Double guard coating cannot be utilized to welded parts.)
Substantial Guard Coating
High guard coated surface has superb corrosion resistance.
The surface of the chain is finished in non-gloss white hugely protective coating. It’s excellent resistance to salt corrosion and rusting. This coating protects chains in high temperatures as it can resist heat as much as about 250°C.
Considering that high guard coating acts as a sacrificial anode for that chain entire body, you’ll be able to count on adequate corrosion resistance even if the coating has come off to some extent. Also, it could possibly be utilized to welded elements.
It is actually advisable for outside use or close to the sea in circumstances the place functionality as high as that of stainless steel will not be vital. In conditions that require resistance to alkaline and acid, double guard or stainless steel coating is encouraged as they have much better resistance than substantial guard.
Plating is generally done with nickel. It is actually a coating with the two appealing exterior and corrosion resistance. By using it with grease lubrication, it exhibits fantastic corrosion resistance. You could count on the impact to delay hydrogen brittle destruction when used in circumstances in which chains are exposed to sea breeze or acidic sprays.
(Double guard coating cannot be applied to welded parts.)
