Surface Treatments

Stainless Steel

Stainless steels have the characteristic of superficially present a chromium oxide layer (formed in air or artificially, by means of chemical product) very thin and invisible that protects the material from environmental attacks.

In case of heat treatment, welding or high stress is prevented the formation of the chromium oxide layer, for this reason stainless steels tend to oxidize.

 

To guarantee the stainlessness of stainless steel, it’s ESSENTIAL an OPERATION SCHEDULE as follows:

 

DEGREASING / DEOXIDATION TREATMENT;

PICKLING TREATMENT;

PASSIVATING TREATMENT;

ELECTRO-POLISHING;

FINISHING.
