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.
