P20*

1. 본문

"P20" can refer to several different things:
P20 Steel:

• Definition: P20 is a versatile, low-alloy tool steel known for its good toughness at moderate strength levels. It's a pre-hardened plastic mold steel that offers uniform hardness even across large sections.
• Uses: It is commonly used for plastic injection mold cavities and tooling, die-casting dies for zinc, large mold frames, bolsters, and machine-cut plastic molds. It is also good for tooling and die holders.
• Properties:
• Good toughness and moderate strength.
• Excellent dimensional stability during heat treatment.
• Good weldability.
• Capable of achieving an excellent polished finish.
• Can be hardened further through case hardening or nitriding for applications requiring maximum surface hardness (e.g., compression molding plastic dies).
• Contains Chromium and Molybdenum (chrome-moly alloy steel).

• An event that aims to add a parliamentary dimension to global governance. Its goals include raising awareness and building political support for international commitments and ensuring these commitments translate into national realities.
