Heat treatment of M2 high-speed steel

The following information is provided for guidance only. The rate of heating, cooling and soaking times will vary due to the shape and size of each component and other external factors.

Annealing

Heat the M2 high-speed steel to 850 - 900°C. Hold at temperature for at least two hours or one hour per 25 mm of thickness. Furnace cool slowly. The maximum hardness should be 248 Brinell.

Stress relieving

Stress relieving M2 is recommended after machining or grinding and before hardening to minimise the chance of distortion. Heat the component to 600 - 700°C and soak well (for approximately two hours), then cool in air.

Hardening

Pre heat the M2 in two steps; 450 - 500°C then 850 - 900°C. Then continue heating to the final hardening temperature of 1200 - 1250°C. Do not leave the steel too long at the hardening temperature. Quench in warm oil or brine to about 500°C then air cool down to room temperature.

Tempering

Heat the M2 to the required tempering temperature, hold at temperature for at least two hours or one hour per 25 mm of thickness. Double tempering is recommended.

Applications:

The well balance properties of M35 means it is used in a wide range of cutting tools where demands for hot hardness are moderate, such as twist drills, reamers, broaching tools, milling tools, taps and metal saws. M35 is also suitable for cold work applications such as tools for punching, forming and pressing. If you are looking for superior red-hardness then consider M42 high speed steel.

Product Details:

For mordern industrial production, particularly mass production, machining is one of the most important shaping and forming processes. Almost all tools employed for this purpose are made from high speed steels. In recent times, the use of high speed steels has also gained increasing importance for chipless shaping, eg. for extrusion, blanking and punching tools. With regard to chemical composition, distinction made between W-, Mo- and W-Mo alloyed steel grades which, depending on the dominant stress they will be exposed to contain different amounts of carbon, vanadium and cobalt.

 

The characteristic properties of all high speed steel grades includes:

• High working hardness
• High wear resistance
• High retention of hardness and red hardness
• Excellent toughness

Product Details:

T42 high-speed steel is a tungsten-molybdenum tool steel. M35 is characterised by well-balanced toughness, wear resistance and red hardness properties. AISI T42 high-speed steel has largely replaced T1 in most applications due to its superior properties and advantageous pricing. T42 is medium-alloyed and is a good all-round performer with good machinability, in this respect it is superior to the high alloyed cold work steels.

High Speed Steel Square Bar T42

For modern industrial production, in particular mass production, machining is one of the most important shaping and forming processes. Almost all tools employed for this purpose are made from high speed steels. The characteristic properties of all high speed steels grades include.

• High working hardness
• High wear hardness
• Excellent toughness
• High retention of hardness and red hardness

 

Influence of alloying elements on the steel properties:

• Carbon: Forms carbides, increases wear resistance, is responsible for the basic matrix hardness.
• Tungsten and Molybdenum: Improves red hardnesss, retention of hardness and high temperature strength of the matrix, form special carbides of great hardness.
• Vanadium: Forms special carbides of supreme hardness, increase high temperature wear resistance, retention of hardness and high temperature strength of the matrix.
• Chromium: Promotes deep hardening, produces readily soluble carbides.
• Cobalt: Improves red hardness and retention of hardness of the matrix.
• Aluminium: Improves retention of hardness and red hardness. Since it is possible to achieve specific properties by careful adjustment of these alloying elements, we are able to offer the most suitable high speed steel grade for virtually all kinds of application.

Product Details:

M3 high speed steel is a cobalt molybdenum tools steel, the addition of 8% cobalt means that M3 delivers superior red-hardness when compared to M3. The composition of M3 makes for a good balance of toughness and hardness and can be found widely used for all types of cutting tools, often used for machining materials and super alloys that are difficult to machine. M42 high speed steel has a heat-treated hardness in the range 68 to 70 HRC.
