BACM ASOCHROME 65

Chrome plated Steel bars Introduction.

Chrome plated steel bars are the most common products used as piston rods for hydraulic cylinders in applications operating in standard conditions. We recommend A-CHROME BACM made from 20MnV6 steel for the piston rods of standard hydraulic cylinders that need an excellent machinability and weldability.Chrome plated steel bars made from 20MnV6 are recommended by our technical department at low temperature environments.Chrome plated steel bars are used also to build pneumatic cylinder with pressures higher than 200 bars.
Applications for standard conditions are applications working in a non-particular corrosive environment.

SubtitleA-CHROME BACM 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 0,3 [mm]/1000 [mm] and for ∅≥20[mm] is max 0,2[mm]/1000[mm].
Chrome Layer thickness for ∅≤19.05 [mm] is minimum 15[µm] and for ∅>20[mm] is minimum 20[µm].Corrosion Resistance results are based on a salt spray tests. 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 steel bars corrosion resistance.

Standard Corrosion Resistance for Φ<20 is R9/120h and for Φ≥20 is R9/200h according to NSS tests.
EXTRA Corrosion Resistance for Φ≥20-140 is R10/120h and R9/500h according to NSS tests.
EXTRA PLUS Corrosion Resistance for Φ≥20-140 is R10/500h according to NSS tests.

We can provide Double Chrome Layer at premium price.Weldability excellent due to the micro – alloying effect of the vanadium having high yield and tensile strengths.Machinability excellent due to silicon – calcium treatment and precise control of the Sulphur content.Packaging A-CHROME products are supplied in 3 different packaging options. Our standard packaging is made with plastic sleeves or paper tubes (depending 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.

SubtitleMarking 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.
