Hastelloy is in nikkel-basearre korrosysje-resistint alloy, dy't foaral ferdield is yn twa kategoryen: nikkel-chromium alloy en nikkel-chromium-molybdenum-molybden-molybden-molybden-molybdeen Hastelloy hat goede korrosje wjerstân en thermyske stabiliteit, en wurdt meast brûkt yn loftfeart, gemyske fjilden, ensfh.
Ernicrmo-4Wurdt brûkt foar gas-wolwier-ARC- en gas-metaal-ARC-welding fan Incel Alloy C-276 en oare nikkel-chromium-molybdenum-molybdenum. Fanwegen hege molybdenum-ynhâld biedt dizze alloy poerbêste ferset tsjin stress corrosie-kraken en pitting en crevice-korrosysje.
