Nimonic PE16 Alloy Sheet
Nimonic PE16 Alloy Sheet 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.
Heat Treatment
Nimonic PE16 has to be solution annealed at 1038°C (1900°F) for 4 h and then air cooled. This process is repeated twice at 799°C (1470°F) for 2 h and air cooled, and at 699°C (1290°F) for 16 h and air cooled, so as to complete the precipitation hardening process.

Forming
Nimonic PE16 alloy sheet has good ductility and can be easily formed using all the conventional methods. This alloy is stronger than regular steel; hence it requires a more powerful equipment to complete the forming process. It is recommended that heavy-duty lubricants be used while cold forming. At the end of this process all traces of lubricant has to be cleaned off to prevent embrittlement.
Welding
Nimonic PE16 can be welded using traditional welding methods. Some of the commonly used methods are shielded metal-arc welding, gas metal-arc welding, submerged-arc welding, and gas-tungsten arc welding. It is recommended that matching alloy filler metal should be used and that the weld beads should be slightly convex. Before the welding process begins, the surface to be welded should be cleaned and should be free from oil, paint or crayon stains.
Forging
Nimonic PE16 can be forged at 1176-968°C (2150-1775°F).
Hot Working
Nimonic PE16 can be hot worked at 1176-954°C (2150-1750°F).
Cold Working
Cold working can be performed using standard tooling. It is better to avoid using plain carbon tool steels for forming as they cause galling. To minimize galling and provide a neat finish, soft die materials containing bronze and zinc alloys are recommended. However, the life of the die is short. Likewise, heavy duty lubricants should be used to reduce galling in all forming operations.
Application
Nimonic PE16 is mainly used in high temperature oxidizing applications, especially in cases where strength at temperature is a primary requirement, e.g. industrial furnace components or gas turbine hot sections.
- Gas turbine flame tubes
- Nuclear reactor parts
- Missile hot components
- Super heater tubing
- Aircraft ducting systems
