Special AlloysSheet/Plate
Description (English)
HASTELLOY Alloy 6 is supplied in the sheet solution heat-treated condition, delivering yield strength of 317 MPa, tensile strength of 703 MPa, elongation of 62%, and hardness of HRB 84. 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 exceptional ductility (62%) provides outstanding formability for complex fabrications. HASTELLOY 6 is widely used in chemical processing, pulp and paper production, and flue gas desulfurization systems where balanced corrosion resistance and good fabricability are required.
