It is a high-strength and high-toughness martensitic aging steel, belonging to the iron-nickel-cobalt-molybdenum alloy, containing a small amount of titanium and aluminum elements, and has excellent mechanical and technological properties. It is widely applied in fields such as aerospace, energy and chemical engineering.
Excellent mechanical properties
- High yield strength and ultimate tensile strength
- High toughness, ductility and impact strength
- High fatigue strength
- High compressive strength
- Its hardness and wear resistance are sufficient to meet the requirements of many tool applications
Excellent processability
- It is easy to process
- Easy to form – cold, hot or hot (no intermediate annealing required) high resistance to crack propagation
- Excellent polishing performance
- Good welding performance
Excellent heat treatment characteristics: Low furnace temperature requirements for precipitation hardening and aging heat treatment:
Uniform and predictable shrinkage during heat treatment
- The minimum deformation during heat treatment does not require quenching for full hardening and does not need a protective atmosphere
- It is not affected by sulfation or desulfation
Advantages during the application process
A low coefficient of expansion can minimize thermal stress to the greatest extent
- Its pitting corrosion resistance and corrosion resistance are superior to those of ordinary tool steel
- Good repair welding performance
- Excellent mechanical properties lead to a longer tool life, making it easier to reprocess and anneal to extend the secondary tool life
The density of this alloy is ρ=8.0/cm³.
