Product Details:

M35 High Speed Steel

AISI M35 Tool Steel is a Cobalt-Type high speed tool steel. M35 steel is on the basis of M2 Steel, but with 5% Cobalt content increased which makes better hot hardness and wear resistance. AISI M35 Steel is suitable for heat treatment up to 66 HRC, and offers excellent cutting performance.

Quenched and Tempered (+QT) of M35 Steel
1. Preheat aisi M35 steel slowly to the temperature of 730-840°C;
2. Keep heating up to hardening temperature of 1200-1220°C;
3. Make sure that the material is heated throughly;
4. Quench in the oil or brine;
5. Heat uniformly to the required tempering temperature;
6. Withdraw M35 steel from the furnace and cool in air;
7. The general tempering temperature is 540-560°C which can make the material at 65HRC.
8. The M35 tool steel is also suitable for vacuum hardening and triple tempering is strongly recommended.

 

Applications of AISI M35 Steel
M35 tool steel is usually used in conditions where the demand for hot hardness is high, such as cutting tools including broaches, milling cutters, reamers, end mills and saw blades. It is also a good quality wear resistant HSS grade for cold work area.

M2 high-speed steel is a tungsten-molybdenum tool steel. M2 is characterised by well-balanced toughness, wear resistance and red hardness properties.

AISI M2 high-speed steel has largely replaced T1 in most applications due to its superior properties and advantageous pricing. M2 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.

M42 high speed steel is a cobalt molybdenum tools steel, the addition of 8% cobalt means that M42 delivers superior red-hardness when compared to M2. The composition of M42 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.
