Hot Work Tool Steel 1.2343 is a high-performance tool steel known for its durability and resistance to heat and wear. Here’s a detailed description of this steel:
### **Chemical Composition:**1. **Carbon (C):** Approximately 0.38-0.45%2. **Chromium (Cr):** Around 4.8-5.5%3. **Molybdenum (Mo):** About 1.0-1.2%4. **Vanadium (V):** Approximately 0.8-1.2%5. **Others:** May include traces of elements like silicon (Si), manganese (Mn), and phosphorus (P) depending on specific alloy variations.
### **Properties:**- **Heat Resistance:** Excellent heat resistance, maintaining strength and hardness at elevated temperatures, making it suitable for hot work applications.- **Wear Resistance:** Good resistance to wear and abrasion due to its carbide structure.- **Toughness:** High toughness ensures resistance to cracking and chipping during high-stress operations.- **Hardness:** Can be hardened to approximately 55-60 HRC (Rockwell Hardness Scale) depending on the heat treatment process.
### **Applications:**- **Forging Dies:** Used in manufacturing dies and molds for forging hot metals.- **Extrusion Dies:** Ideal for dies used in extrusion processes where high temperatures and pressures are involved.- **Hot Punches and Tools:** Suitable for tools that are subjected to high temperatures and impact during operation.
### **Heat Treatment:**- **Hardening:** Typically involves heating to a temperature around 1020-1050°C (1868-1922°F) followed by quenching.- **Tempering:** Post-hardening tempering is usually performed to achieve desired toughness and reduce brittleness, with tempering temperatures ranging from 500-700°C (932-1292°F).
### **Advantages:**- **Long Tool Life:** Enhanced durability and resistance to thermal and mechanical stresses extend the life of tools made from this steel.- **Dimensional Stability:** Maintains shape and dimensions well under high-temperature conditions.
### **Standards and Specifications:**1. **DIN:** This steel is standardized under the German DIN standard as DIN 1.2343.2. **AISI/SAE:** Equivalent to AISI H11 in the American standard system.
1.2343 is often used in the manufacturing of high-precision hot work tools due to its ability to withstand severe operating conditions and maintain performance over time.
