Edge Retention Steel Raw Material Wear Resistance 420 Stainless Steel Plate

Product Specification

420 Stainless Steel Raw Material for Superior Edge Retention and Wear Resistance in Industrial Applications

Product Overview:

420 Stainless Steel is a high-carbon martensitic stainless steel renowned for its exceptional hardness, wear resistance, and edge retention. With a carbon content (0.15-0.40%) higher than 410 stainless steel, it achieves superior strength and hardness after heat treatment, making it the preferred choice for cutting tools, surgical instruments, and industrial molds. Its balanced composition (12-14% chromium) provides moderate corrosion resistance, ideal for applications demanding durability in non-marine environments.

Key Physical Properties

• Chemical Composition: Cr (12-14%), C (0.15-0.40%), Mn (≤1%), Si (≤1%), Fe (Balance)

• Hardness (Annealed): 200-250 HB | Hardness (Hardened): 50-55 HRC

• Tensile Strength (Rm): 650-850 MPa (Annealed) | Up to 1600 MPa (Heat-Treated)

• Yield Strength (Rp0.2): 350-600 MPa (Annealed) | Up to 1350 MPa (Heat-Treated)

• Elongation (A5): 15-20% (Annealed) | 5-10% (Heat-Treated)

• Density: 7.7 g/cm³

Product Features:

1. Ultra-High Hardness & Wear Resistance

   • Achieves 50-55 HRC after heat treatment, outperforming 410 stainless steel in edge retention and abrasion resistance.

   • Ideal for blades, molds, and components subjected to repetitive friction.

2. Precision Machinability

   • Easily machined in annealed state; hardened post-machining for sharp, durable edges.

   • Compatible with grinding, polishing, and precision CNC processes.

3. Moderate Corrosion Resistance

   • Resists water, steam, and mild chemicals, suitable for food processing, medical, and industrial tools.

   • Not recommended for chloride-rich environments (e.g., seawater) – consider austenitic grades (e.g., 316) for such cases.

4. Heat-Treatable Versatility

   • Customizable through quenching and tempering to balance hardness, toughness, and stress resistance.

   • Optional cryogenic treatment enhances wear performance for critical applications.

5. Cost-Effective Durability

   • Lower nickel content reduces costs compared to austenitic steels, while offering superior hardness.
