DIN 1.2083 steel is a high-performance tool steel that combines wear resistance and corrosion resistance, making it suitable for various demanding applications in the tooling industry. Its properties make it ideal for molds and dies, especially in environments where corrosion is a concern.
Chemical Composition:
- Carbon (C): 0.40 - 0.50%
- Chromium (Cr): 12.00 - 14.00%
- Molybdenum (Mo): 0.5 - 1.0%
- Manganese (Mn): ≤ 1.00%
- Silicon (Si): ≤ 1.00%
- Phosphorus (P): ≤ 0.03%
- Sulfur (S): ≤ 0.03%
Mechanical Properties:
- Hardness (HRC): 50 - 56 HRC (after heat treatment)
- Tensile Strength: Approximately 1,200 - 1,400 MPa
- Yield Strength: Approx. 1,000 MPa
- Elongation: 8 - 12%
Physical Properties:
- Density: Approximately 7.8 g/cm³
- Thermal Conductivity: About 25 W/m·K
- Modulus of Elasticity: Approximately 210 GPa
Applications:
- DIN 1.2083 is commonly used for:
- Injection molds for plastic
- Die-casting molds
- Blades and cutting tools
- Components requiring good corrosion resistance and wear resistance
Heat Treatment:
- Hardening: Typically austenitized at 1000 - 1050°C, followed by oil or air quenching.
- Tempering: Tempered at 200 - 500°C to achieve the desired balance between hardness and toughness.
Machinability:
- Machinability is moderate; carbide tools are recommended. Using cutting fluids can enhance performance and tool life.
Welding:
- Welding of DIN 1.2083 can be challenging due to its high chromium content. If welding is required, preheating and the use of low-hydrogen filler materials are recommended.
Key Advantages:
- Excellent wear resistance
- Good corrosion resistance
- High hardness and dimensional stability
