01H18N40M5GB-ID (EP753-ID)
The technological characteristic is corrosion resistance: the forged billet is tested for intergranular corrosion by a regulated method.
Forged pipes and pipe fittings for petrochemistry, for special equipment of nuclear power plants and for the needs of instrument-making are made of an alloy.
