Special AlloysSheet/Plate
Description (English)
HASTELLOY Alloy N is supplied in the sheet solution heat-treated condition, delivering yield strength of 310 MPa, tensile strength of 793 MPa, elongation of 51%, and hardness of HRB 96. The alloy is manufactured to multiple ASTM standards covering sheet/plate (B 434), rod (B 573), and fittings (B 366). The good ductility (51%) combined with high molybdenum content provides excellent resistance to fluoride salt corrosion. HASTELLOY N is widely used in nuclear power generation, fluoride salt processing, and high-temperature molten salt applications.
