Excellent quality and best effeciency of Strong Metal heat treating equipment are the main factors why our customers choose us as their heat treatment equipment supplier in the long run.
Bright annealing is an annealing process performed in a vacuum or a controlled atmosphere containing inert gases (such as Ammonia decomposing gas, hydrogen). This controlled atmosphere reduces the surface oxidation to a minimum which results in a brighter surface and a much thinner oxide layer. Pickling is not needed after bright annealing since the oxidation is minimal. Since there is no pickling, the surface is much smoother which results in better resistance to pitting corrosion.
