Hastelloy C-4
High-temperature stable Ni-Cr-Mo alloy free of intergranular precipitation for chemical equipment.
Introduction
§01 — GeneralHastelloy C-4 is a nickel-chromium-molybdenum alloy specifically designed to resist the formation of grain-boundary precipitates during welding and elevated-temperature exposure. This high-temperature stability makes it suitable for chemical process equipment operating in the as-welded condition without post-weld heat treatment.
