Product details
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.
