Hard Chrome is a very hard surface coating (usually in the region of 950-1150 H.V) with a very low coefficient of friction surface. It is used throughout many industries in a number of different types of applications.
 Hydraulic rams and cylinder piston rods Earth moving equipments Materrial Handling equipmet Wire wound rods for paper coating Seal areas on pump or drive shafts Conveyer wear rails and rollers Plastic extruder screws Print rollers Machine spindles or housings Motorcycle forks Cardboard tube formers Pump shafts or rotors |

Hydrogen Relief:
During plating, copious amounts of hydrogen are released at the cathode (part being plated). As much as 85% of the current applied during chrome plating goes to form hydrogen. Some of the hydrogen is occluded in the basis metal during plating, setting up stresses that can cause hardened metal to crack.
In general, metal with hardness greater than 40 Rc should be relieved by heating the jobs upto 200°C for a period of 2 hours.Tulip Engineers got a facility to remove hydrogen with a capacity of 3 Met length furnace.
