Heat treatment - Betz Chrom EN

Heat treatment. The heat treatment process is employed with both chemical nickel and hard chromium process technologies. Heat treatment serves as a preventative measure for the resistance of high strength steel parts against hydrogen induced brittle fractures, in accordance with DIN 50969 (colloquially referred to as hydrogen diffusion annealing).

Hard chromium - Betz Chrom EN

Hard chromium - The special surface protection against wear and corrosion. Hard chromium plating is primarily used in the field of wear stress. The ability of the chrome, in conjunction with oxygen, to form a dense oxide layer lends hard chromium plating its extremely good corrosion resistance and its anti-adhesive properties.
