Forging of NM400 Steels
Forging NM 400 plate / sheet involves heating the material to a specific temperature before shaping it. This process enhances the steel's mechanical properties, making it more suitable for various applications. Proper forging techniques are crucial to maintain the integrity of NM400 grade steel.
Heat Treatment of NM400 Wear-Resistant Steel
Heat treatment of NM 400 sheet involves processes like annealing, normalizing, quenching, and tempering to enhance its mechanical properties. These treatments help in achieving the desired hardness and strength, making NM400 Steel more resilient to wear and tear. But for raw material supplying, we usually supply NM 400 plate in Q+T condition.
- Solution Treatment: Heat to 1050-1100°C, hold, then rapidly cool (usually in water).
- Aging Treatment: Heat at 200-500°C for an extended period.
- Quenching: Heat to 900-1000°C, then rapidly cool.
- Tempering: Reheat quenched steel to 200-600°C, then cool.
- Normalizing: Heat to 850-950°C, then air cool.
- Annealing: Heat to 700-800°C, hold, then slowly cool.
NM400 Surface Finish
Surface Hardening: Includes flame and induction hardening.
Carburizing: Heat in a carbon-rich environment at high temperature.
Nitriding: Heat in a nitrogen or ammonia atmosphere.
Carbonitriding: Similar to carburizing but with nitrogen addition.
Electroplating: Electrochemically deposit a metal layer (e.g., chromium, nickel).
Thermal Spraying: Apply a high-hardness, wear-resistant coating.
