          1045/50 High Strength S-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:

          Grade AISI 1045/50
