DK Conveyor Chains Standard Conveyor Chain
Classification by Surface Treatment
There are a variety of selection for heat treatment and specifications for the conveyor chains. Specific treatments can
be applied not only to the chain as a whole but to each component separately, such as pins or plates only.
Select desired combinations in reference to the following explanation of features and uses.

Conveyor Chain
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 materials. It exhibits nearly doubled corrosive resistance
in the salt water spray test compared to our conventional high guard coating, and can be used in mild alkaline or mild
acidic conditions up to pH3.
With its improved corrosive resistance, it can be used in circumstances where high guard or plated coatings cannot be
used, and even in some conditions where only stainless steel can be used.
(Double guard coating cannot be applied to welded parts.)

High guard coated surface has superb corrosion resistance.
The surface of the chain is finished in non-gloss white highly protective coating. It has excellent resistance to salt
corrosion and rusting. This coating protects chains in high temperatures as it can resist heat up to about 250°C.
Since high guard coating acts as a sacrificial anode for the chain body, you can expect sufficient corrosion resistance
even when the coating has come off to some extent. Also, it can be applied to welded parts.
It is recommended for outdoor use or near the sea in circumstances where performance as high as that of stainless
steel is not necessary. In circumstances that require resistance to alkaline and acid, double guard or stainless steel
coating is recommended as they have better resistance than high guard.

Plating is mostly done with nickel. It is a coating with both appealing exterior and corrosion resistance. By using it with
grease lubrication, it exhibits excellent corrosion resistance. You can expect the effect to delay hydrogen brittle
destruction when used in circumstances where chains are exposed to sea breeze or acidic sprays.
(Double guard coating cannot be applied to welded parts.)
