HEAT TREATMENT:

Annealing: 1.3243/M35 is supplied in the annealed and machineable condition. Re annealing will only be necessary if the steel has been hot worked, forged, or hardened by the toolmaker. Heat the M35 hss bar high speed steel to 850°C at a rate of no more than 220°C per hour. Always hold at temperature for one hour per 25mm of thickness (with two hours being minimum). Furnace cool slowly. M35 annealed hardness achieved should be 260 Brinell or lower.
