DIN1.2311/AISI P20 plastic mould steel

1. Standard and Grade:
DIN1.2311, ASSAB 618,DIN1.2312, AISI P20

2. Size:
round or flat according to customer's request

Hardness 28-32HRC

3. Chemical composition:

4. Applications:
Thermoplastic injection mold and extrusion mold
Thermoplastic blowing mold
Main parts of heavy-duty mold
Structural fabrications
Usually used for manufacture of television casing, washing machine, refrigerator
Inner casing, and water-pot.

5. Characteristics:
Pure steel quality due to vacuum degassing treatment
The screwing die is formed by forging, and the flat steel and round steel are formed by rolling at a high ratio of deformation. It is compact in structure, suitable for making the plastic molds requiring Polish or etch machining.
Porosity occurs if the thickness of rolled sheet is higher than 120mm. It is not recommended for use to the molds with mirror polishing requirements.
