(redirected from Hastalloy)



the name of a group of corrosion-resistant nickel alloys, namely the Ni—Mo and the Ni—Cr—Mo alloys. Depending on the desired combination of properties, Hastelloys contain varying amounts of Mo (up to 30 percent), Cr (up to 23 percent), Fe (up to 29 percent), and C (up to 0.15 percent). Some are alloyed with W (about 5 percent), Si (up to 10 percent), Co (up to 2.5 percent), or Cu, V, Ta, Nb, and other elements.

Hastelloys are characterized by high resistance to hydrochloric, sulfuric, phosphoric, acetic, and formic acids, to media containing ions of chlorine and fluorine, and to many organic media. Produced in the form of sheets, rods, wires, and castings, they are used mainly in the manufacture of chemical apparatus; some are used as heat-resistant materials. The brands N70M28F and Khl5N65M16V, among others, are produced in the USSR.
