Hastelloy G35 alloy is an alloy developed in G30. This alloy increases chromium to 33% and molybdenum to 8%. The development of these alloys is mainly for more satisfactory corrosion-resistant structural materials for concentrated evaporators in the production of wet-process phosphoric acid. It is a nickel-chromium-molybdenum alloy containing tungsten. It has a very low silicon-carbon content and is considered a corrosion-resistant alloy.
