Hastelloy

 

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.

For this pump application, due to the corrosive nature of the acid involved Seepex engineers proposed that internal metal parts were therefore manufactured from chemical resistant hastalloy and the pump casing of halar-coated cast iron which have proved ideal.

Instead of paying as much as (currently) $56,000 a (short) ton for ferromolybdenum, for example, to make a Hastalloy, a mill can use scrap Hastalloy inserts collected as described here as a feed to provide all of the necessary alloy elements in the correct proportion and significantly reduce the need for new ferrometal alloys.
