Mn13 Heat Treatment Instructions

1. Solution Treatment:
   Heat to 1050-1100°C, hold, then rapidly cool (usually in water). Eliminates internal stress, improves toughness and ductility.
2. Aging Treatment:
   Heat at 200-500°C for an extended period. Precipitation hardens to increase strength and hardness.
3. Quenching:
   Heat to 900-1000°C, then rapidly cool. Significantly increases hardness and wear resistance, but may reduce toughness.
4. Tempering:
   Reheat quenched steel to 200-600°C, then cool. Reduces brittleness, increases toughness and ductility.
5. Normalizing:
   Heat above Ac3 or Ac4 (850-950°C), then air cool. Enhances mechanical properties and refines grain structure.
6. Annealing:
   Heat above Ac1 (700-800°C), hold, then slowly cool. Reduces hardness, improves plasticity and toughness, relieves internal stress.

Mn13 Surface Finish

1. Surface Hardening:
   Includes flame and induction hardening. Rapid surface heating followed by cooling to harden and increase wear resistance.
2. Carburizing:
   Heat in a carbon-rich environment at high temperature. Carbon diffuses into the surface, enhancing hardness and wear resistance.
3. Nitriding:
   Heat in a nitrogen or ammonia atmosphere. Nitrogen atoms diffuse into the surface, forming a hard layer with improved hardness and corrosion resistance.
4. Carbonitriding:
   Similar to carburizing but with nitrogen addition. Enhances surface hardness and wear resistance.
5. Electroplating:
   Electrochemically deposit a metal layer (e.g., chromium, nickel) on the steel surface. Improves wear resistance, corrosion resistance, and appearance.
6. Thermal Spraying:
   Apply a high-hardness, wear-resistant coating (e.g., aluminum oxide, tungsten carbide) using thermal spraying techniques.

Custom surface treatment requirements can be accommodated upon request.
