Ni-Hard Impeller

Ni-Hard is used for abrasion resistant applications where there is  extreme temperature. It is used in an environment where the temperature is high such as in thermal power plant. Our Ni-hard impeller offers excellent abrasion resistant properties which increases the overall service life of the Ni-hard impeller.High content of nickel in our Ni-hard impeller promotes austenite grain formation which causes these impellers to become abrasion and heat resistant.

We manufacture Ni-hard impeller in various size and dimension for all kinds of screw impeller mixture machine and pump impeller manufactured by various companies around the world. Weight of each Ni-hard impeller manufactured by us can range from25 kgs. to upto 1050 kgs. single piece. We accept large quantity order for these blow bars. Ni-hard impeller is manufactured as per IS : 4771 – 1985 type 1A to upto type 3

All the Ni-hard impeller is properly and strictly checked for its chemical properties on 37 channel analysis Spectro Inc. Germany make spectrometer by tapping liquid metal directly from the induction furnace. Ni-hard impellers are generally used in the as cast condition. But for heavier section thickness castings it is perfectly annealed in a state of the art electric hearth heat treatment furnace having programmable PLC based temperature controller and chartless recorder.

After the annealing heat treatment process is complete metallography test of samples is done on a 1000x magnification metallurgical microscopealong-with support of image analysis software both imported from Italy to determine the grain structure and matrix formation which in-turn helps to know thesoundness of the Ni-hard impeller. Hardness is than measured directly on the blow bar using digital hardness tester imported from Proceq Switzerland.

We are supplying Ni-hard impeller tothermal power plants and stone mining queries located in Jharkhand, West Bengal, Assam.
