9CrWMN die steel is a low-alloy cold work die steel. The steel has some hardenability.

and wear resistance, quenching deformation is small, carbide distribution is uniform, and particles are fine.

9CrWMN die steel is usually used to manufacture cold stamping dies with small cross-sections and complex shapes, as well as various gauge measuring tools. 1) It is used to make cold stamping dies with complex shapes and precision.

2) It can be used to make thin stamping.

Touch, decorated embossing molds, etc.

3) It is more suitable for making deformed and complex cutting tools with long shapes, such as drawing and long taps.

Long hinge, special milling.

4) For integral hardened plastic molds.

5) In the forming of thermosetting plastics, it is required to be wear-resistant and strong.

9CRWMN mold steel is required to have certain strength, hardness, wear resistance, thermal stability and corrosion resistance.

9CrWMN die steel has some crack sensitivity, forging heating should not be heated quickly, it is best to preheat at 650-750 degrees, the forging heating temperature is 1130-1150 degrees, the final forging temperature should be greater than 800-850 degrees, and the upper limit temperature is taken when forging the ingot.

35Cr1Mn is an alloy steel whose chemical composition includes:- Carbon(C):Silicon(Si):

Manganese (Mn): Chromium (Cr): Phosphorus (P):

Sulfur (S): This kind of gold steel has high strength and wear resistance, and is often used in the manufacture of parts that require high strength and wear resistance, such as mechanical zero rollers, bearings, gears, etc.

Qinqin, 35Cr1Mn is a kind of alloy steel in the world, and its chemical cover is destroyed as follows: carbon (C): silicon (Si):

Manganese (mn): phosphorus (p): sulfur (s) material preparation:

Chromium (Cr): Nickel (Ni): Copper (Cu):

Molybdenum (Mo): The above is the typical chemical composition of 35Cr1Mn alloy steel, the specific composition may vary depending on the manufacturer and production batch.

9CRWMN] is an alloy tool steel. Reference standard GB T1299-2000 GB T 1299-2000 "Alloy Tool Steel", the chemical composition is shown in the following table: [Alloy Tool Steel] is a type of steel grade that adds chromium, molybdenum, tungsten, vanadium and other alloying elements on the basis of carbon tool steel to improve hardenability, toughness, wear resistance and heat resistance.

It is mainly used in the manufacture of measuring tools, cutting tools, impact-resistant tools, cold and hot molds and some special purpose tools.
