  Chrome Plated Bar   is typically used for hydraulic cylinder rods. It is stocked in two basic conditions; Chrome Plated Only and IHCP bar ( Induction Hardened Chrome Plated ). The primary difference is that IHCP bars are induction hardened to give a hard case on the surface for support to the chrome plating; this minimizes surface damage to the chrome from abrasion and/or impact. Also, AISI 1045/50 Chrome Plated and IHCP are both available in standard and high strength properties. Thickness of chrome plating is designated as either Standard (0.0005″ min.) or Heavy (0.001″ min.). HERE BELOW IS THE APPLICATION LIST OF THE CHROME RODS: Hydraulic cylinders  (chrome plated piston rods) Pneumatic cylinders / air cylinders (hydraulic cylinder piston rods)  Guide rods for plastic manufacturing machine and hydraulic machinery Rollers for machines, such as packing machine rollers, printing machine rollers Shaft for machinery, such as Textile machinery center axle, Transport ...

  AISI 1045  chrome plated shaft  is cold drawn, precision ground and polished shafting with a seam free surface finish of RMS 25 max. The bars are then hard chrome plated by electrolytically deposited layer of chromium metal on the surface. This hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance. Stainless Steel is an iron-based metal alloy, with added elements including chromium, nickel, silicon and carbon. These elements are mixed into the base material itself, and are present throughout the entire structure of the shafts.   The surface of the Stainless Steel is then finely polished to a mirror finish. Because the Stainless properties are evident throughout the entire bar, any damage or scratches can simply be re-polished to expose the fresh new material underneath. As a pro...

  Two methods have become established for hardening workpieces in mass production: case hardening and induction hardening. A comparison of these two methods shows their differences and the advantages of each. Case Hardening vs. Induction Hardening – a Comparison If one compares the two methods for hardening steel workpieces (for a general explanation of hardening see here: Hardening), then the first striking difference is the parts handling. While case hardening processes a large number of workpieces at the same time, induction hardening focuses on the individual workpiece. With induction hardening, components are hardened workpiece . For case hardening, “batch by batch” would be a better description. Of courses, this has an impact on the manufacturing. While case hardening relies on parts logistics to carry parts between the production line and hardening, induction hardening can be integrated directly in the production line with a suitable hardening machine (e.g. MIND series) and ...

  The   induction hardened piston rod   is typically a hard chrome-plated piece of cold-rolled steel which attaches to the piston and extends from the cylinder through the rod-end head. In double rod-end cylinders, the actuator has a rod extending from both sides of the piston and out both ends of the barrel. The piston rod connects the hydraulic actuator to the machine component doing the work. This connection can be in the form of a machine thread or a mounting attachment. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage. Induction hardened is a form of heat treatment in which a metal part is heated by induction heating. Induction hardened piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them. The hardness after this heat treatment is HRC 40 to 45. External Diameter Tolerance:  Our  chrome plated b...

Ck45  induction hardened chrome plated bar  is used extensively by the hydraulic and pneumatic industries, for those applications utilising its high surface hardness and excellent resistance to surface impact. Induction hardened: Induction hardened is a form of heat treatment in which a metal part is heated by induction heating. Induction hardening of piston rods in hydraulic cylinders is performed in order to increase the resistance to damage from external impact in applications where there is risk for them. The hardness after this heat treatment is HRC 40 to 45. Surface hardness:  min. 900 HV0.1 (66 HRC) the surface hardness in the induction-hardened zone immediately beneath the chrome layer is min. 55 HRC (HV 595). Hardening depth:  0.75 – 4.0mm depending on the diameter. Other hardening depths can be supplied by special arrangement. Corrosion resistance:  min. 120 – 200 hours in Neutral Salt Spray testing according to ISO 9227 standard or its equivalents, co...
