Rotor housing for rotary piston engines having a base and a chromium-plated inner wall. The base is made of an iron-based material having a hardness of not less than 105 in Vickers' scale and the chromium-plated layer has a hardness not less than 850 in Vickers' scale. The rotor housing is used with a rotor having apex seals of iron-based material which includes 50 to 75% in volume of carbide at least in a sliding surface which is adapted to be brought into sliding engagement with the inner wall of the rotor housing, said apex seal having a hardness of 700 to 900 in Vickers' scale at the sliding surface.
