  The process of   induction hardened bar   can enhance the mechanical properties of ferrous and alloy components in a specific part. Typically, the material of doing induction hardening includes  CK45 , 20MnV6,  4140  and 4340. First, the piston rod will be put into a copper coil, and it’s heated by alternating current. Then, the outer surface of the  cylinder piston rod  will be heated to a temperature above the transformation range. After that, the piston rod will be tempered immediately to adjust the hardness level.  The final surface hardness of the induction hardened rod will be HRC 55° ± 2°. The chrome layer hardness is 850 HV0.1. The surface hardness in the induction hardened zone immediately beneath the chrome layer is 55 HRC min. The depth of hardening is between 1.0 and 3.0 mm depending on dimension. As a professional  chrome plated bar  supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 ye...

  Chrome plating is used to provide a very high degree of hardness on the surface of a  cylinder piston rod  to enhance wear resistance,reduce friction,provide anti-galling properties, and in some cases, improve corrosion resistance. Chrome plating is an electrolytic process that can be applied to regular steel cylinder rod, stainless steel cylinder rod  and other materials. For cylinder rods, leading  hydraulic cylinder  parts manufacturer , Wuxi YUTONG  can make chrome thickness of min 20/25/30/50 Micron or customized. the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these  chrome plated rods , thereby helping the consumer save the cost. Our chrome plated rod are manufactured with high dimension precision, tolerance can be ISO f7, f8 or g6, upon request. Which ensures the precision of the hydraulic cylinder or the machine.
