Chrome Bars

Mirraloy® HCP

(C.P.O.) Hard, Chrome Plated, Polished Shaft

Mirraloy HCP offers salt spray corrosion resistance. Chrome hardness is Rockwell “C” 58/60.  It is a precision finished chrome plated shaft, minus the induction hardened surface of the shaft substrate. The outer surface of the shaft has high hardness chrome, the sub-surface of the shaft, (under the chrome), is not hardened. It is an excellent extended service chromed shaft material for hydraulic and pneumatic  applications when a conventional approach to machining is available.  Call or email us for a quote.

Rigid quality standards ensure excellent internal soundness and uniformity of chemistry.  Surface condition and wearability are verified.  An excellent choice for hydraulic and pneumatic applications.

Key Features

Chrome Plated – .001″ per side of uniform chrome plating which is twice the industry standard, less likely to show “pitting” than other chrome plated products.

Abrasion Resistant – offers excellent abrasion resistance in maintenance applications where sliding wear causes premature failure.

Corrosion Resistant – performed well in salt spray tests.

Polished Finish – superior micro finish in the range of 12/15 RMS
