Tungsten Molybdenum High Speed Aisi M2 Steel Product - China

M2 High Speed Steel Performance

M2 steel is a hot-processed high-speed tool steel with many excellent properties.

Due to these advantages, it is widely used in the market.

(1) High hardness and high wear resistance.

M2 high-speed steel is composed of high content of tungsten, molybdenum, cobalt and other elements, which makes its hardness and wear resistance very high.

(2) Good heat resistance, good processability and high hardenability.

(3) Good heat treatment stability.

(4) Good machining performance.

(5) Has excellent thermohardness.

(6) High reliability: M2 high speed steel has a very long service life, making it one of the main cutting materials.

(7) It has extremely high anti-fatigue cutting ability and stability, so that it can still maintain its performance after long-term use.

Machinability

The shaping of M2 tool steels may be executed using grinding strategies.

But, which has bad grinding capability.

So they’re called as “medium” machinability tool steel under annealed conditions.

The machinability of these steels is only 50% of that of the easily machinable W group or water hardening tool steels.

Annealing

Heat to 1600° F, soak thoroughly at heat.

Furnace cool 25° F per hour to 900° F, air cool to room temperature.

Approximate annealed hardness 241 Maximum Brinell.

Stress Relief of Unhardened Material: Heat slowly to 1200 to 1250° F.

Soak for two hours per inch of thickness at heat.

Slow cool(furnace cool if possible) to room temperature.

Hardening

Heat M2 steel slowly to 1550° F, soak fully, heat to 1850° F, soak thoroughly.

Soak time in the furnace varies from a few minutes to 15 minutes, depending on tool size, the heat capacity of the furnace, and the size of the charge.

– Heat to 2150 to 2200° F for max.

toughness and minimum distortion.

– Heat to 2250 to 2275° F for max.

Tempering

Double tempering is necessary, sometimes preferred three times tempering.

Soak for 2 hours per inch of thickness.

Air cool to room temperature between tempers.

The best tempering range for hardness, strength and toughness is 1000 to 1050° F.

Quenching

For full hardness, need to oil quench to 150-200° F.

Air quenches to 150° F.

When quenching in hot salt maintains the quench just above the Ms temperature.

After equalizing withdraw parts from the hot salt and air cooled to 150° F.

M2 high speed steel is preheated prior to hardening at 2610 ° C(4730 ° F).

Then heated rapidly from 2610 ° C (4730 ° F) to 3960 ° C (7160 ° F).

The steel is finally cooled for 3 to 5 minutes and quenched in air, salt bath or oil.
