EN10204 Steel Grinding Chrome Rod 42CrMo4+QT

 42CrMo4 is a heat treatable steel which contains at least 0.9%Cr,0.15%Mo as strengthening elements. After quenched and tempered, It obtains high strength, good low-temperature impact toughness with a typical tensile strength of 900 -1200 N/mm2.42CrMo4 steel has better performance than 34CrMo4 steel due to the higher carbon and chromium content.Similar to AISI 4140,only a little difference in Mn,Cr content.This material also has good machinability,good wear-resistance,but the temper brittleness is not obvious,and poor in weldability.

CHrome rod 42CrMo4 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.

The Advantages Of our  Hard Chrome Plated Rod 42Crmo4

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, 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.
