Acralloy® H-CPO®

Chrome Plated Product

PACIFIC Chrome Plated Bar is typically used for hydraulic cylinder rods. It is stocked in two basic conditions; CPO® (Chrome Plated Only) and IHCP® (Induction Hardened and Chrome Plated). The primary difference is that IHCP® bars are induction hardened to give a hard case on the surface for support to the chrome plating; this minimizes surface damage to the chrome from abrasion and/or impact.

Also, AISI 1045/50 CPO® and IHCP® are both available in standard and high strength properties. Thickness of chrome plating is designated as either Standard (0.0005" min.) or Heavy (0.001" min.).

CPO® bars are also stocked in Acralloy® and Stressproof® grades. Acralloy® offers the strength and toughness of a quenched and tempered alloy steel; Stressproof® gives high strength with free machining characteristics.

Types and grades of PACIFIC Chrome Plated Bar are listed below:
