Applications

• Forgings and mechanical parts in stainless steel requiring very good mechanical properties as well as good resistance to fatigue and sudden rupture.
Better coefficient of friction than austenitic stainless steels.

Characteristics

• Precipitation hardened martensitic stainless steel.
• Melting: consumable electrode remelted steel.
• Good mechanical properties in the longitudinal and transverse directions.
• Excellent toughness, ductility and fatigue properties.
• Good resistance to various corrosive agents.
• Good weldability.
