HARD CHROMIUM PLATED BARS WITH
HIGH CORROSION RESISTANCE

THE PRODUCT MIX


Stelmi produces a variety of chromium plated bars
with increasing corrosion resistance:


Hiperchromium ® 200


Hiperchromium ® 500

Hiperchromium ® 1000


The base material can be carbon steel (Ck45), or micro-alloyed steel (20MnV6, 45MnV1), or quenched and tempered steel (42CrMo4), eventually induction hardened.
Corrosion resistance is tested according to ISO 9227 , receiving a "rating" according to ISO 10.289.

As previously mentioned in section "Quality" , the specification UNI ISO 9227, provides a description of the methods and the equipment to be used for corrosion tests.
