	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.
