AMS5759 specification covers a corrosion- and heat-resistant cobalt alloy (L605 / Haynes 25 / UNS R30605) in the form of bars, forgings, flash-welded rings, and stock for forging, flash-welded rings, or heading.

Alloy L605 is a cobalt-nickel-chromium-tungsten alloy with exceptional strength and good oxidation resistance in environments up to 1093°C (2000°F) for prolonged exposures.

The alloy offers good fabricability, forming, welding, and machining. It provides good resistance to wear and galling and is ideal for applications that require good strength with oxidation resistance at elevated temperatures.

Specifications & Available

Alloy L605 represents one of the strongest fabricable cobalt alloys currently available. The attractive performance characteristics of the alloy make it highly suitable for applications including aircraft engines, gas turbines, and ball bearings. The alloy is supplied in the solution heat-treated condition.

Available Forms: Round bar, flat bar, forgings, flash-welded rings, forging stock, heading stock
Specifications: AMS5759, ASTM B572, UNS R30605, Werkstoff Nr. 2.4964

Fabrication

Solution Annealing: 1177-1232°C (2150-2250°F), rapid air or water quench
Hot Working: 1177-1232°C (2150-2250°F); reheat as necessary
Cold Working: Good formability; work-hardening rate rapid
Machining: Good machinability; requires rigid setups, sharp tools, and adequate coolant
Welding: Good weldability using GTAW (TIG), GMAW (MIG), and resistance welding; matching filler metal recommended
