3 OVERVIEW
Alloy L-605 is a nonmagnetic solid solution strengthened cobalt-chromium-tungsten-nickel alloy with excellent high-temperature strength and excellent oxidation resistance to 2000°F (1093°C). The alloy also offers good resistance to sulfidation and resistance to wear and galling. The high temperature strength results from solid-solution strengthening by tungsten with second phase strengthening by precipitated carbides. As a result of its high Tungsten content, Alloy L-605 is radiopaque, which is beneficial for implant devices. Elsewhere, this grade is known as alloy 25.
Alloy L-605 can only be hardened significantly by cold working. Cold working will increase creep strength up to 1800°F and stress rupture strength up to 1500°F. Strain aging at 700-1100°F improve creep and stress rupture strengths below 1300°F.
4 General application
Alloy L-605 is useful applications include medical implant devices, springs, valves, and in the hot sections of aircraft gas turbine applications such as rings, blades and combustion chamber parts (sheet fabrications) and can also can be used in industrial furnace applications such as muffles or liners in high temperature kilns.

8 WORKING INSTRUCTION
Hot working
The metal temperature during hot working should be greater than 1900°F but less than 2300°F to avoid ductility loss and subsequent cracking. In this temperature range, the alloy is readily hot formable. Above this range, nil ductility will prevent any formation and below this range, the alloy will harden quickly.
Cold forming
It is preferable to cold-work the alloy for bending, deep drawing and spinning of components. This is facilitated by the excellent as annealed ductility of the alloy, however, high forces may be required to achieve such processing, due to the inherent strength of the alloy. It may therefore be necessary to interstage anneal the material after each step of processing due to the work hardening of the alloy that will be encountered. Annealing at 2150°F - 2250°F (1175- 1230°C) is required to allow for subsequent working of cold-worked material. The hardness of the alloy reaches the mid 40s on the Rockwell 'C' scale by 25% cold work and can reach the upper 50s.
Fabricating
Alloy 188 has good fabricability, though it work hardens rapidly. Forming, machining and welding can be carried out by standard methods.
9 HEAT TREATMENT
Annealing
For maximum softness, this steel should be heated uniformly to 1550/1600ºF (843/871ºC). Soak and cool very slowly in the furnace. Brinell hardness approximately 223. Intermediate or process annealing treatment-heat uniformly to 1350/1400ºF (732/760ºC). Air cool. Brinell hardness about 255.
Hardening
Heat to 1850/1950ºF (1010/1066ºC); soak; quench in warm oil or cool in air. Do not overheat. When overheated, full hardness cannot be obtained. See comments under corrosion resistance.
Tempering
Hardness of approximately Rockwell C 60 will be obtained. To remove peak stresses and yet retain maximum hardness, temper at least one hour at 300/350ºF (149/177ºC).
