Applications
• Closed-die forgings for the aerospace industry
• This alloy has been specifically designed for structural components subject to high fatigue stress and risk of corrosion
• This alloy allows the manufacturing of very thick parts (up to 250 mm / 10″)
Characteristics
• This alloy used in T852 condition achieves a balance between mechanical properties (strength, toughness and fatigue) and stress corrosion resistance
• Its good hardenability makes it suitable for producing very thick parts
