Hastelloy G-30 -- the phosphoric acid specialist Ni alloy. Outstanding resistance to wet-process phosphoric acid (WPA), oxidising acids and mixed acid environments. For fertilizer plant absorbers, phosphoric acid evaporators and sulphuric acid coolers.
Hastelloy G-30 (UNS N06030) per ASTM B582. High Cr (28-31.5%) + W + Cu gives outstanding wet-process phosphoric acid (WPA) resistance -- better than standard 904L or C-276 in hot concentrated H3PO4. Standard for WPA process equipment: evaporators, heat exchangers, pumps and agitators. The dominant alloy for fertilizer plant H3PO4 service.
