There are actually several different selection for heat treatment and specs for the conveyor chains. Distinct treatment options can be applied not just to the chain as being a whole but to each and every part separately, this kind of as pins or plates only.
Select sought after combinations in reference towards the following explanation of options and utilizes.
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 various resources. It exhibits just about doubled corrosive resistance in the salt water spray test compared to our traditional substantial guard coating, and will be used in mild alkaline or mild acidic situations up to pH3.
With its improved corrosive resistance, it might be utilized in situations where high guard or plated coatings cannot be used, and even in some disorders wherever only stainless steel can be employed.
(Double guard coating can’t be utilized to welded parts.)
High Guard Coating
High guard coated surface has fantastic corrosion resistance.
The surface in the chain is completed in non-gloss white hugely protective coating. It’s superb resistance to salt corrosion and rusting. This coating protects chains in substantial temperatures because it can resist heat up to about 250°C.
Considering the fact that higher guard coating acts as being a sacrificial anode for the chain body, you could assume adequate corrosion resistance even if the coating has come off to some extent. Also, it could possibly be applied to welded elements.
It’s encouraged for outdoor use or near the sea in circumstances where effectiveness as higher as that of stainless steel isn’t important. In situations that demand resistance to alkaline and acid, double guard or stainless steel coating is encouraged because they have improved resistance than high guard.
Plating is mainly accomplished with nickel. It truly is a coating with the two appealing exterior and corrosion resistance. Through the use of it with grease lubrication, it exhibits outstanding corrosion resistance. You may anticipate the impact to delay hydrogen brittle destruction when utilized in circumstances wherever chains are exposed to sea breeze or acidic sprays.
