Hastelloy C-4 Properties: This alloy is an austenitic low carbon nickel-molybdenum-chromium alloy. The main differences between Nicrofer 6616 hMo and other earlier developed alloys of similar chemical composition are the lower carbon, silicon, iron, and tungsten content. Such a chemical composition makes it exhibit excellent stability at 650-1040°C, improves the ability to resist intergranular corrosion, and can avoid edge line corrosion sensitivity and weld heat-affected zone corrosion under appropriate manufacturing conditions.

Application areas: flue gas desulfurization systems, pickling and acid regeneration plants, titanium dioxide production (chlorine method), chemical fields of wet chlorine, hypochlorous acid, hydrochloric acid, chloride, acetic acid and acetic anhydride, flue gas desulfurization systems, electrolytic plating, etc. .
