Depending on the environment where the
CROMEST based hydraulic component is going to
be used, there are different levels of corrosion
resistance to meet the challenge.
The standard CROMEST products as indicated in the brochure have one chrome layer, but to enhance corrosion resistance in more demanding and aggressive environments, CROMEST HR should be used. CROMEST HR can be produced in all the CROMEST grades.
CROMEST HR has double chrome layers for increased corrosion resistance. Two layers reduce the risk that the external environment can penetrate and attack the underlying steel.
CROMEST HR guarantees NSS 400 h rating 9.
