P20 STEEL
Description
P20 steel PLATES is a widely used tool steel known for its high toughness, wear resistance, and machinability.
It is commonly used in plastic mold manufacturing, die-casting dies, and injection molds.
Here are some key details about P20 steel PLATES:-
p20 material chemical composition/ Chemical Composition (Typical)
Element Percentage (%)
Carbon (C) 0.28 - 0.40
Chromium (Cr) 1.40 - 2.00
Manganese (Mn) 0.60 - 1.00
Molybdenum (Mo) 0.30 - 0.55
Silicon (Si) 0.20 - 0.80
Sulfur (S) ≤ 0.030
Phosphorus (P) ≤ 0.030
Properties of P20 steel PLATES.
• Hardness (Pre-Hardened Condition): 28-32 HRC
• Toughness: High
• Machinability: Good
• Polishability: Excellent
• Heat Treatability: Can be nitrided or carburized for better hardness
• Corrosion Resistance: Moderate
Applications
• Plastic injection molds
• Die casting dies
• Pressing dies
• Blow molds for plastics
• Automotive and aerospace tooling
Heat Treatment
• Annealing: 760-790°C, slow cooling
• Hardening: 840-870°C, followed by oil or air cooling
• Tempering: Typically done at 500-600°C to achieve the desired hardness
Variants
• P20+S: Improved sulfur content for better machinability.
• P20+Ni (P20HH): Higher nickel content for better toughness and uniform hardness.
