PROPRIETARY CPM S30V Heat Treatments

SOFT ANNEAL ING is heated uniformly at a temperature of 900 °C; maintain the temperature for 2 hours and allow to cool slowly to 600 °C in the furnace at a cooling rate of max. 15 °C per hour. It is then further cooled in still air. The hardness achieved by soft annealing is approx. HB 275. STRESS RELIEVING After machining it is recommended to subject the work piece to a stress relieving process at a temperature of 600 - 700 °C for a thermal holding period of 2 hours duration. HARDENING it is to be preheated slowly and thoroughly to a temperature of 840 - 870 °C. Further heating in the furnace continues until an austenitizing temperature of 1150 - 1180 °C is reached. The holding time after complete penetration amounts to 1 0 -3 0 minutes (lower temperatures require longer soaking times). The lower end of the austenitizing temperature range should be selected to attain maximum toughness, whilst the top end of the range produces maximum wear and corrosion resistance. We recommend hardening to be carried out in a vacuum or a protective gas. QUENCHING it can be cooled in air, in protective gas, in hot bath or in oil. To achieve maximum toughness salt bath quenching at a temperature of approx. 540 °C, followed by immediate residual quenching in still air down to less than 40 °C is recommended. In the case of heat treatment in a vacuum quenching must be undertaken at a pressure of at least 5 bar down to below 40 °C. TEMPERING Immediately temper after the material has cooled down below 50 °C, it is normally tempered through two tempering stages, each of 2 hours duration at 200 - 400 °C. If required, cooling to sub-zero temperatures can be carried out between the first and the second tempering cycle to fully destroy any re-austenitic formation. The first tempering process should always be concluded prior to any sub-zero cooling process.
