There are several different choice for heat treatment and specifications for your conveyor chains. Certain treatment options is usually utilized not just towards the chain like a full but to every single component separately, such as pins or plates only.
Select wanted combinations in reference on the following explanation of characteristics and uses.
Double Guard Coating
The surface is treated with outstanding corrosion resistant coating that approaches the resistance of stainless steel. Double guard coating consists of double layers of two different products. It exhibits virtually doubled corrosive resistance during the salt water spray test in contrast to our traditional high guard coating, and can be used in mild alkaline or mild acidic disorders up to pH3.
With its improved corrosive resistance, it might be used in circumstances wherever higher guard or plated coatings cannot be used, as well as in some situations where only stainless steel can be made use of.
(Double guard coating can't be applied to welded components.)
Substantial Guard Coating
High guard coated surface has fantastic corrosion resistance.
The surface of the chain is completed in non-gloss white really protective coating. It has superb resistance to salt corrosion and rusting. This coating protects chains in high temperatures as it can resist heat up to about 250°C.
Because large guard coating acts as a sacrificial anode to the chain entire body, it is possible to assume ample corrosion resistance even when the coating has come off to some extent. Also, it might be utilized to welded elements.
It is proposed for outside use or close to the sea in circumstances in which effectiveness as substantial as that of stainless steel is just not essential. In situations that need resistance to alkaline and acid, double guard or stainless steel coating is advised as they have much better resistance than high guard.
Plating is mainly performed with nickel. It is a coating with both appealing exterior and corrosion resistance. By utilizing it with grease lubrication, it exhibits outstanding corrosion resistance. You are able to assume the effect to delay hydrogen brittle destruction when utilized in situations exactly where chains are exposed to sea breeze or acidic sprays.
