AISI M42 Steel Round Bar US grade AISI M42 Steel Round Bar technology

M42 tool steel is high-speed steel with high cobalt. And it also is called JIS
SKH59 and DIN 1.3247 steel. It is mainly used for high toughness precision
wear-resistant hardware cold stamping die and cutting tools. It has high
toughness and hardness, could reach to 70HRC. Its hot hardness is high and easy
to grind and cut. The cutting tools which are made of M42 steel can cut cast
superalloys, titanium alloys, and ultra-high-strength steels. But the toughness
is a little bad, the temperature should be lower during the quenching. It is
used widely to manufacture high precision and complex cutting tools because of
its great grinding properties. M42 Steel round bar sheet plate properties and
heat treat as below.

1.3247 Steel Characteristics
1.The content of cobalt is 8% or 10%

2.Great wear resistance, hardness and hot hardness

3.Has excellent red hardness and cutting performance

4.Be used widely in industry, such as cutting tools, milling cutters and etc

5.Has high impact ductility

M42 Steel Application
The application is decided by M42 steel chemical composition and properties.

1.It is used to make a variety of wear-resistant, impact-resistant tools for
powerful cutting.

2.It is used to produce a variety of high-hard and saw blades, drills, taps,
broaches, hobs and milling cutters.

3.It is the material of advanced dies, screw dies and punches that require more
toughness and complex

shapes.

4.It is used for cold forging dies and deep drawing dies.
