- Aerospace industry: Used in components requiring high durability and corrosion resistance.
- Oil and gas industry: Suitable for equipment and accessories operating in harsh environments.
Hardness
Certification: AS9100, ISO 9001:2015, ISO 14001:2015
Standard: JIS, ASTM, EN, DIN, GB, AMS, UNS...
Chemical composition (%): Chemical composition:
- Chromium (Cr): 16-18%, provides corrosion resistance and shine.
- Nickel (Ni): 8-12%, improves toughness and heat resistance.
- Molybdenum (Mo): 2-3%, enhances corrosion resistance in environments containing chloride.
- Carbon (C): Maximum 0.15%, helps improve hardness and abrasion resistance.
- Manganese (Mn): 2%, supports steel structure.
- Silicon (Si): 1%, helps improve corrosion resistance and machining.

Physical properties:
- High Hardness: Provides better durability and wear resistance than standard stainless steel.
- Corrosion resistance: Retains high corrosion resistance, especially in harsh environments.
- Toughness: Despite its high hardness, steel still maintains good machinability and bending properties.
