|Form of Supply|
West Yorkshire Steel are stockholders and suppliers of round bar. Diameters can be sawn to your required lengths as one offs or multiple cut pieces. Ground steel bar can be supplied, providing a high quality high speed steel precision ground bar to tight tolerances.
|M42 Tool Bits|
M42 high speed steel tool bits are supplied in flats, squares and rounds. Commonly supplied in standards sizes though non standard metric and imperial sizes can be produced within a few weeks, subject to availability of suitable raw material.
M42 high speed steel can be used in conditions where the demand for hot hardness is important. Commonly used for cutting tools including twist drills, taps, broaches tools, milling cutters, reamers, end mills, bandsaw blades, cold work tools.
Pre heat the M42 high speed steel slowly and uniformly to 650-760°C and equalise. Then increase more quickly to the forging temperature of 1010-1150°C and equalise prior to forging. Do not allow the forging temperature to drop below 980°C, if this occurs re heating will be necessary. Always cool the high speed steel very slowly after forging.
Annealing of M42 is recommended after hot working and before re hardening. Heat the M42 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. The M42 annealed hardness achieved should be 269 Brinell or lower.
If tools produced from M42 high speed steel are heavily machined or ground it is recommended to stress relieve after machining and prior to hardening to minimise the possibility of distortion. To stress relieve heat the component to 600-650°C and soak well (approximately two hours) Cool slowly in the furnace. The M42 tools can be finish machined before heat treatment.
