42CrMo4 polished chrome rod is mainly used for hydraulic cylinder.The piston rod material 42CrMo4 hardened and hard chrome plated with the material number 1.7225 is suitable for heavy use and is especially wear-resistant thanks to its hardened surface layer with a surface hardness of 56–64 HRC.
Due to the material’s high stability very high forces can be transmitted, e.g. for small connecting threads with large piston rods.
The Advantages Of our 42Crmo4 polished chrome rod
1.Hard chrome plating means that an especially thick chrome layer is applied after the pre-honing and before finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV. Hard chrome plated piston rods can be used between -15°C and 200°C.
2.High quality raw material: our raw material mainly from some famous steel mills, such as TPCO, BAO STEEL, SHA STEEL, which are best and largest raw material manufacturer in China.
3.High precision: Chrome Plated Rod, quenched and tempered, chrome layer 10 micron to 100 micron, strict tolerance ISO f7.
4.Strict quality control: we have professional in-house QC to inspect all products. We will do Chemical Composition Test, Mechanical Property Test, Dimension Inspect, Roughness Test, Chrome Layer Test and other tests in need before delivery.
