Turbine rotor shafts

Sandvik supplies turbine rotor shafts produced by powder metallurgically based hot isostatic pressing (PM HIP).

One example is the 12% chromium steel compound rotor in which the PM HIP technology makes it possible to join a different material in the bearing area with perfect bonding to the 12% chromium steel. The material in the bearing area reduces the rate of wear during operation.

HIP advantages

Using HIP products instead of, for example, castings and forgings mean several advantages, such as less machining and welding.
