Factory Supply M2 Steel Round Bar For Sale - China

AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series.

HSS grade steel M2 is a medium alloyed high speed steel which has good machinability.

The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties.

Widely used for cutting tools such as twist drills, taps, milling cutters, saws, knives etc.

Also commonly used in cold work punches and dies and cutting applications involving high speed and light cuts.

Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel grade T1 in most applications because of its superior properties and relative economy.

We are one of leading AISI M2 HSS steel supplier and we can offer better quality and M2 alloy steel price for your various applications.

M2 Steel Application

The application is decided by M2 steel chemical composition and properties.

It has high hardness, red hardness.

Good thermoplasticity and excellent toughness.

It is used to make tools that require has good wear resistance and toughness which can sustain large impact forces.

Such as pinion cutters, planers, milling cutters, turning tools, drill bits and etc.

M2 Steel Characteristics

Hardness (factory state): ≤255HB

Curing Temperature: 1220℃-1240℃

Hardness (after heat treatment): ≤ 63 HRC

It is a good choice for cutting applications due to its high wear resistance and toughness.

Carbide evenly distributed and high toughness.

Can be used to make milling cutters, reamers, broaches, gear cutters and other industrial tools.

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.
