Application:

The alloy of this unification is particularly suitable to pieces that are strongly hot and cold stressed and

it has a good resistance to general and marine corrosion. It also has remarkable qualities of attrition

and cavitation resistance.

Application cases: turbine seals, nozzles and Pelton wheel pins, strongly stressed bearings,

pieces of ordnance, valve housings and tracks for engines.
