The main characteristics of ASSAB88 Assab assab:

ASSAB 88 is a chromium, molybdenum, vanadium alloy tool steel, its characteristic is:

1 high wear resistance

2 good breakage resistance

3 high compressive strength

4·After high temperature tempering hardness high ( > 60HRC )

5 good hardenability

6 quenched and good dimensional stability

7 good temper softening resistance

8, line cutting.

9, machining and milling.

10 surface treatment characteristics

Assab 1-100 ASSAB88 main use:

ASSAB 88 is a multipurpose cold work tool steel. It has good resistance to mixed / abrasive wear resistance and its angle of.

After high temperature tempering can obtain very high hardness ( > 60HRC ).

Therefore, the high hardness ( > HRC60 ) of large section under complex shape with line cutting die, can reduce the cracking risk.

In addition, the high strength matrix suitable for surface treatment such as nitride or PVD.

ASSAB 88 is mainly used for secondary production and need to have good abrasive or mixed abrasion and good resistance to collapse angle of die.

Application examples:

1, punching and stamping

2 shear

3 forming

4 impression

5 cold forging

6 cold extrusion

7 twist wire

8 tensile and deep drawing

9 Powder Compaction
