Forging of High Speed M42 Tool Steel
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 reheating will be necessary. Always cool the m42 high speed steel very slowly after forging.


Machinability
AISI Steel grade M42 tool steel can be drilled, turned, threaded, broached, milled and tapped when it is in its annealed condition and rated at 45% of 1% carbon steel.


Heat Treatment of M42 Tool Steel High-speed steel material
* Annealing
AISI M42 high speed steel is heated at 871°C (1599°F) and then cooled slowly in a furnace.
* Stress Relieving
to relieve stresses created by extensive machining or tooling with complex geometries. Heat in a neutral atmosphere for 1 to 2 hours after reaching a temperature of 1110 to 1200°F (600 to 650°C), followed by slow cooling in the furnace.
* Hardening
AISI M42 high speed steel is preheated to 871°C (1599°F), soaked and finally heated to 1204°C (2199°F).
* Tempering
Tempering M42 tool steel at 560°C / 1040°F or higher 3 times for at least 1 hour at full temperature is recommended.

Application of M42 Tool Steel High Speed
AISI M42 tool steel is a high-speed steel suitable for cutting tools such as, twist drills, broaches, taps, milling, cutters,
Saws, reamers etc. in terms of performance, HSS grade M42 is a steel to be used in conditions where the demand for hot hardness is of great importance i.e. Where high performance is essential.
Typically employed to machine the super alloys and exotic, AISI HSS M42 tool steel is employed in drills, hobs, taps, end mills, milling cutters, form and gear cutters, broaches and chasers.
