Acid Potassium Chloride Zinc Electroplating Brightener

Process of hydrogen removal:

190-230 ℃

More than 3 hours

Carburizing and tin welding parts temperature 140℃-160℃

Hydrogen removal should be carried out immediately after plating, and the parts should be scrapped after more than 4 hours.

Other steel parts must be dehydrogenated within 4 hours after electroplating.

Spring parts, thin-wall parts (wall thickness less than 0.5mm), high-strength steel parts, must be dehydrogenated.

Copper and copper alloy parts can be free of hydrogen removal.

For parts that cannot be heated too high, a lower temperature (140℃-160℃) can be used to extend the time of hydrogen removal.
