Applications
• Very heavily stressed parts requiring good corrosion resistance and very good mechanical properties.
• Aerospace industry.
Mechanical properties
• Precipitation hardened stainless steel of very high purity, vacuum melted and consumable electrode remelted.
• Excellent mechanical properties in the longitudinal and transverse directions.
• Excellent balance between strength, toughness and fatigue properties, especially at the 1400 N/mm2 strength level (>PH13-8Mo).
• Good resistance to corrosion and stress corrosion.
• Good weldability.
