Chemical Composition:

- Carbon (C): 2.20 - 2.40%

- Chromium (Cr): 11.00 - 13.00%

- Molybdenum (Mo): 0.70 - 1.20%

- Vanadium (V): 0.10 - 0.30%

- Manganese (Mn): ≤ 0.50%

- Silicon (Si): ≤ 0.50%

- Phosphorus (P): ≤ 0.03%

- Sulfur (S): ≤ 0.03%

Mechanical Properties:

- Hardness (HRC): 54 - 60 HRC (after heat treatment)

- Tensile Strength: Approximately 1,800 - 2,100 MPa

- Yield Strength: Approx. 1,600 MPa

- Elongation: 5 - 10%

Physical Properties:

- Density: Approximately 7.7 g/cm³

- Thermal Conductivity: About 25 W/m·K

- Modulus of Elasticity: Approximately 210 GPa

Applications:

- Commonly used for:

  - Cold work dies

  - Punches and cutting tools

  - Molds for plastic injection and die-casting

  - Shear blades

Heat Treatment:

- Hardening: Typically done through austenitizing at 1000 - 1050°C, followed by oil quenching.

- Tempering: Usually tempered at 500 - 600°C to achieve the desired hardness and toughness.

Machinability:

- Moderate machinability; requires appropriate cutting tools and techniques due to high hardness. Pre-heating tools and using cutting fluids can improve performance.

Welding:

- Welding is not generally recommended due to the risk of cracking. If welding is necessary, use suitable filler materials and preheat the workpiece.

Key Advantages:

- High wear resistance and toughness

- Suitable for heavy-duty applications

- Excellent dimensional stability during heat treatment
