P20 plastic die steel belongs to hot work die steel, is the introduction of the United States of P20 carbon CR-Mo plastic die steel.P20 plastic mold steel is suitable for making plastic mold and die casting low melting point metal mold material.P20 plastic die steel has good machined-ability and mirror grinding performance.

P20 plastic die steel with regular specifications and condition .

The thickness as the below generally :

20-120mm/130-150mm/155-180/100-150/155-200/205-230/205-250/260-300mm

P20 plastic die steel regular condition :

l EAF+LF+VD+HOT ROLLED + PRE-HARDEN

l EAF+LF+VD+HOT ROLLED + PRE-HARDEN + Black Surface

There have the stock for the thickness of 20-180mm in China Steel Marketing .

P20 plastic die steel factory has been pre-hardened to 285-330HB (30-36HRC), and The status of Sweden 618 Germany GS-2311, can be directly used for mold processing, and has the characteristics of good dimensional stability, pre-hardened steel can meet the needs of general use, P20 plastic die steel mold life can reach 50W times.

P20 plastic die steel general application:

● Thermoplastic plastic injection mold, extrusion mold.

● Thermoplastic blow molding mold.

● Heavy duty mold main parts.

● Cold structure parts.

● It is often used to manufacture TV case, washing machine, refrigerator inner shell, bucket and so on.

P20 plastic die steel generally China Steel Marketing can have the stock in plate and flat bar with available specification  over to 10mm .

P20 plastic die steel with pre-hardened condition after they finished from the factory with generally 28-32 HRC in hardness.

P20 plastic die steel with new production with around 40-55days .

P20 plastic die steel it is very favorable selection for making the plastic mould in industrial .

P20 die steel performance characteristics

1. P20 die steel has uniform hardness physical characteristics, and has good polishing performance and light etching performance, and P20 die steel processing performance is excellent.Therefore, it is suitable for TV front shell, telephone, water dispenser, vacuum cleaner and other plastic mold and mold frame.

2.through vacuum degassing refining treatment to make P20 die steel steel pure, more suitable for polishing or etching processing plastic mold.Such as: TV case, refrigerator inner shell.

3.P20 die steel has been pre-hardened to 285-330HB(30-36HRC), which can be directly used for mold processing without heat treatment, greatly shortening the construction period and saving its operating cost.And P20 die steel has the characteristics of good dimensional stability, pre-hardened steel can meet the needs of general use, mold life can reach 50W times.Suitable for thermoplastic plastic injection mold, extrusion mold.

4.P20 die steel after forging and rolling processing of its physical characteristics of dense organization, ultrasonic inspection can be found that P20 die steel without holes and pinhole defects.Therefore, it is used to make washing machines, buckets and other molds that need strong sealing.
