Chrome plated Stainless Steel bars Introduction.

Stainless steel, also known as inox, is a steel alloy with a minimum of 10.5% chromium content by mass.

Our Chrome plated stainless steel bars made from AISI 329 austenitic stainless steel are used in applications working in extreme conditions. Extremes are defined as those working in extremely aggressive conditions.

We recommend A-CHROME BACI 329 for all applications working in a highly acid environment. High resistance to acetic, phosphoric and even sulfuric acids.

A-CHROME BACI 329 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 due to the 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 test results. These tests are following the ISO 9227 and ISO 10289 standards. The results of these tests are giving the rating of our products.

ASO HYDRAULICS & PNEUMATICS chrome plated stainless steel bars.

Corrosion Resistance Performance is provided on request.

Weldability of A-CHROME BACI 329 is good by all standard methods. Welded sections don’t require heat treatment.

Machinability of A-CHROME BACI 329 is good.

Packaging A-CHROME products are supplied in 3 different packaging options.

Our Standard packaging for chrome plated stainless steel bars is made from plastic sleeves or paper tubes. The type of packaging depends on the product’s diameter.

Special Packaging that is seaworthy protected has an additional cost and is made from aluminum foil or vacuum bags.

As an Extra protection with additional cost we can provide also wooden boxes.

SubtitleMarking in ASO HYDRAULICS & PNEUMATICS is done in order to have 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 BACI 329 chrome plated stainless steel bars are delivered having the Rod end painted in green with blue cross.
