Gradual heating to a temperature of about 850°C is recommended prior to more rapid heating to a temperature of between 1150 and 1180°C. Forging then takes place between 950 - 1180°C fol-
lowed by slow cooling is an oven or in dry ash or similar material to promote slow cooling. After forging, the forged components are heat treated to attain the required properties.
The machinability of this heat resistant stainless steel is directly related to its hardness and is
generally considered to machine similarly to carbon steels of the same hardness. Although it
must be realised that the machining parameters will vary depending on the structure/hardness of
the steel, the following parameters can be used as a guideline when using coated hardmetal cut-
