About Alloy
Alloy PE16 is a precipitation-hardenable nickel-iron-chromium alloy with an addition of molybdenum for solid-solution strengthening. PE16 has good strength and oxidation resistance at temperature to about 1380ºF (750ºC). Alloy PE16 is designed to provide a precipitation-hardened material having excellent hot-working, cold-working and welding characteristics. PE16 is commonly used in gas-turbines components and in nuclear reactors.
