Chrome plated Steel bars Introduction.

Chrome plated steel bars made from CW85 steel are used in applications working in demanding and extreme conditions. Applications working in demanding conditions are used in heavy duty and corrosive environment.

Applications working in extreme conditions are used in high corrosive environment. The chemical composition of CW85 steel confers good mechanical properties that can be compared with the ones of QT medium carbon steels.

We recommend chrome plated steel bars made from CW85 steel at piston rods used in complex applications.

A-CHROME BACW Technical Properties.

  • Diameter Tolerance Standard is ISO-f7. We can provide special tolerance at premium price.

  • Residual Magnetism Standard is Max. 50 Gauss. We can provide special magnetism at premium price.

  • Roundness – max ½ from the diameter tolerance.

  • Surface Roughness is Ra = max 0.20 µm.

  • Surface Hardness – Chrome Layer hardness is minimum 900 HV 0,1.

  • Straightness for ∅≥20[mm] is max 0,2[mm]/1000[mm].

  • Chrome Layer thickness for ∅>20[mm] is minimum 20[µm].

  • Corrosion Resistance is given by the salt spray tests results. These tests are following the ISO 9227 and ISO 10289 standards. The results of these tests are giving the rating of our products.

We can provide Double Chrome Layer at premium price.Weldability of these chrome plated steel bars is excellent.Machinability of these chrome plated steel bars is excellent.Packaging A-CHROME products is supplied in 3 different packaging options.Standard packaging of our products is made from plastic sleeves or paper tubes. The packaging solution depends on the product’s diameter.Special Packaging (seaworthy protected) with additional cost is made with aluminum foil or vacuum bags.As an Extra protection with additional cost we can provide also wooden boxes.

Marking in ASO HYDRAULICS & PNEUMATICS has a full trace-ability.

Each bar is marked individually on the plastic/paper tube with info about the date, product series, diameter, tolerance, resistance at saltwater spray test, heat no, production order and so on. The batch has a label with information regarding: Order no, Item no, Heat no, Steel Grade, total length of the batch, Weight, no of pieces in the batch.
A-CHROME BACW chrome plated steel bars are delivered to our customers having the Rod end painted half white and half violet.
