Hastelloy B-3Alloy

HASTELLOY B-3 alloy is an additional member of the nickel-molybdenum family of alloys with excellent resistance to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B-3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. HASTELLOY B-2 alloy. B-3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.

Product form: plate, pipe, coil, bar, flange.

Heat Treatment
All wrought forms of HASTELLOY B-3 alloy are furnished in the solution heat-treated condition unless otherwise specified. B-3 alloy is solution heat-treated at 1950 Fahrenheit (1065 centigrade) and rapid quenched, except for bright annealed sheet or coil products which are heat-treated at 2100 Fahrenheit (1150centigrade) and cooled in hydrogen.

Available in Wrought Form
HASTELLOY B-3 alloy is available in the form of plate, sheet, strip, billet, bar, wire, pipe and tubing.

Applications
HASTELLOY B-3 alloy is suitable for use in all applications previously requiring the use of HASTELLOY B-2 alloy. Like B-2 alloy, B-3 is not recommended for use in the presence of ferric or cupric salts as these salts may cause rapid corrosion failure. Ferric or cupric salts may develop when hydrochloric acid comes in contact with iron or copper.
