Small hot metal objects such as engineering components are quenched in gas by tumbling them in an upward flow of gas distributed uniformly from a multiplicity of openings 18 in the horizontal floor 4 of a quenching chamber 2. The tumbling is performed for a sufficient period of time for the objects to be quenched to a desired temperature. The quenching chamber 2 has a lower region 8 through which the flow of quenching gas is at an uniform velocity and an upper region 10 in which the velocity of the quenching gas is decreased.
