Brief introduction of ASP-23 die steel
Overview of ASP-23: ASP-23 is a kind of high-alloy powder high-speed steel in Sweden. ASP-23 has a good combination of high wear resistance, high toughness and high compressive strength, which is very important for die life. Swedish Yisheng white powder high-speed steel ASP-23 is especially suitable for punching thin processing materials, or dies that fail due to mixed abrasive wear and adhesive wear, or dies whose surfaces are prone to abrasive wear and plastic deformation.

Supply form of ASP-23:

Yuan Pan

round steel

forging stock

Flat steel and square steel

Surface supply forms: wire drawing, centerless polishing, hot working, peeling, rough machining, cold rolling and hot rolling.

Heat treatment technology and hardness of ASP-23;

1. Stress relief process:

After rough machining, the mold should be heated to 600℃~700℃, then kept for two hours, slowly cooled to 500℃, and then cooled in the air.

2. Quenching process:

(1) Preheating temperature: 450~500℃ and 850 ~ 900℃;

⑵ Quenching temperature: choose1050 ~1180℃ according to the required hardness of the die;

(3) Heat preservation time: 30 minutes below 1 100℃, 5 minutes above 1 100℃;

(4) During the quenching process, the mold must be prevented from oxidation or decarbonization.

3. Tempering process:

For the purpose of cold working, no matter what austenitizing temperature is adopted, it is necessary to temper at 560℃ for three times and keep the temperature at least 65438 0 hours each time. It must be cooled to room temperature after each tempering, and the amount of retained austenite after three tempering should be less than 65438 0%.

Factory conditions: soft annealing to about 260HB.

What are the characteristics of ASP-23?

High mildew resistance (wear resistance); High compressive strength; Very good hardenability; Good toughness; Good dimensional stability after heat treatment; Good tempering softening resistance.

Chemical composition of ASP-23,%:

C ..............................................1.28%

Chromium Cr .............................................. 4.00%

Vanadium v .............................................. 3.10%

Tungsten-tungsten ..................................................... 6.40%

Momo ............................................................ 5.00%

What applications is ASP-23 used for?

Swedish Yisheng white powder high-speed steel ASP-23 is especially suitable for blanking and forming thin processing materials, or dies that fail due to mixed abrasive wear and adhesive wear or just abrasive wear, and the risk of surface plastic deformation is high, for example:

Blanking of medium carbon steel or high carbon steel;

3. Stamping hardened steel plate or cold rolled steel strip;

3. Plastic molds containing glass fibers;

Parts of plastic molding machine, such as screw, barrel, nozzle, injection head, crushing knife, etc.

5. Cutting tools, such as gear processing tools, drilling and tapping;

6. High-performance semiconductor integrated circuit molds used for cold plastic processing have long service life, such as cavities and sliders;

Used in silicon steel sheet, printed circuit board die, cold forging die, drawing die, etc. Instead of a cemented carbide die that is prone to corner collapse.
