M35 steel is high speed tool steel . It also is called SKH55 steel and 1.3243 steel. After the heat treatment, its hardness, red hardness and wear resistance can be improved.

M35 high speed steel is a good material for making tools which can handle high impact and abrasion. And it always is used to make advanced die, screw dies, reamer, milling cutter, iron head, punch, complex shape tools with high toughness.

It is easy to do the hot and cold process. After the quenching and tempering, the hardness will be the same as M42 steel . And the hardness of them is 66±1HRC and 67±1 HRC. M35 steel round bar plate sheet properties and chemical composition as below.

M35 Steel Round Bar Application

1. It can be made all kinds of high hardness cutting tools. Such as saw blades, drills, taps, broaches, hobs and various milling cutters.
2.  It is also a good material for cold forging dies, drawing dies, cutting tools, and other similar applications.
3. It is widely used in the cold stamping products industry such as watch case factory and screw factory.

It is suitable for the manufacture of wear-resistant and impact-resistant high-hardness tools for powerful cutting, advanced punching dies, screw dies, tools that require toughness and complex shapes, reamers, milling cutters, iron heads, punches, etc.

The main uses are saw blades, drills, taps, hobs, broaches, end mills and various milling cutters, etc. It is also an excellent material for cold forging dies, wire drawing dies, knives, etc. It is widely used in cold stamping products industries such as watch case factories and screw factories.

1.3243 Steel Characteristics
M35 and M42 are the most popular high speed steel grades in the international. The alloy element content of M35 steel is higher, and also has the cobalt element. So its red hardness is higher. It has great hardness at high temperature. The hot hardness, machinability and wearing resistance are good.
