Abstract
A method for quenching a heated metallic object includes discharging a plurality of discrete gas streams from a plurality of nozzle outlets so that the gas streams impinge substantially uniformly over the outer surface of the object, the distance between each nozzle outlet and the outer surface of the object against which the associated gas stream impinges is less than or equal to half the diameter of the nozzle outlet.
