Introduction of M35 Steel:

M35 is a conventionally manufactured cobalt alloyed high speed tool steel. The various stages of the manufacturing process are chosen and controlled so that an end product is obtained with a good structure in terms of carbide size and distribution.

Application of M35 Steel:

HSS Circular Saw, Blade, Press Mould, Drills, End mill, Planer Knife, Chipper Knife, Slice Knife, Hss Square Tool Bits.

Feature of M35 Steel:

M35 steel is medium-alloyed and has a good machinability containing Cobalt for increased hot hardness. The composition of M35 hss bar makes for a good combination of toughness and hardness. By virtue of these well balanced properties 1.3243/M35 has come into very wide use for cutting tools.

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.
