I-Hastelloyc C-4 yi-austenitic ephantsi ye-carbon nickel-molybdenum chromium alloy.
Umahluko omkhulu phakathi kwe-HastelloyC-4 kunye nezinye ii-alloys eziphuhlisiwe zangaphambili zokwakheka kweekhemikhali ezifanayo yikhabhoni ephantsi, i-ferrosilicate, kunye nomxholo we-tungsten.
Ukwakhiwa kwemichiza enjalo kuyenza ibonise uzinzo olugqwesileyo kwi-650-1040 ℃, iphucule ukukwazi ukuxhathisa i-intergranular corrosion, phantsi kweemeko ezifanelekileyo zokwenziwa kwemveliso kunokuphepha ubuthathaka bomda we-edge kunye nobushushu be-weld obuchaphazeleka kwi-corrosion yendawo.
