Hastelloy are o rezisten\u021b\u0103 excelent\u0103 la coroziune pentru supapele cu glob. Un aliaj N-MO cu con\u021binut extrem de sc\u0103zut de carbon \u0219i c\u0103r\u0103mid\u0103, care reduce precipitarea carburilor \u0219i a altor faze \u00een zona de sudare \u0219i c\u0103ldur\u0103 afectat\u0103, asigur\u00e2nd o bun\u0103 rezisten\u021b\u0103 la coroziune chiar \u0219i \u00een stare sudat\u0103. Dup\u0103 cum se \u0219tie, aliajele Hastelloy au o rezisten\u021b\u0103 excelent\u0103 la coroziune \u00een diferite medii reduc\u0103toare \u0219i pot rezista la coroziune cu acid clorhidric la orice temperatur\u0103 \u0219i concentra\u021bie sub presiune normal\u0103.
