Special AlloysSheet/Plate
Description (English)
HASTELLOY Alloy 6-3 is supplied in the sheet solution heat-treated condition, delivering yield strength of 324 MPa, tensile strength of 690 MPa, elongation of 50%, and hardness of HRB 79. The alloy is manufactured to multiple ASTM standards covering sheet/plate/strip (B 582), rod (B 581), pipe and tube (B 619, B 622, B 626), and fittings (B 366). The good ductility (50%) combined with high chromium and molybdenum content makes the alloy suitable for welded fabrications in the chemical process industry. HASTELLOY 6-3 is widely used in chemical processing, fertilizer production, and marine applications.
