Special AlloysSheet/Plate
Description (English)
HASTELLOY Alloy B-2 is supplied in the sheet solution heat-treated condition, delivering yield strength of 524 MPa, tensile strength of 951 MPa, elongation of 53%, and hardness of HRB 22. The alloy is manufactured to multiple ASTM standards covering sheet/plate/strip (B 333), rod (B 335), pipe and tube (B 619, B 622, B 626), and fittings (B 366). The exceptional ductility (53%) demonstrates the alloy's outstanding formability for fabricated equipment. HASTELLOY B-2 is widely used in the chemical process industry for reactors, heat exchangers, evaporators, scrubbers, and transfer piping handling hydrochloric acid, sulfuric acid, phosphoric acid, acetic acid, and other reducing chemicals.
