overview


NIMONIC alloy PE11 is a nickel-iron-chromium alloy, precipitation hardened by titanium and aluminum and solid solution strengthened by an addition of molybdenum. It was developed as a high-strength sheet alloy for use at temperatures to 1020°C (550°F). The high iron content provides good workability and also relatively high tensile ductility, especially after welding. Used for components of gas turbines.

Corrosion Resistance


Nimonic PE11  offers exceptional strength, corrosion resistance, and creep and fatigue resistance at elevated temperatures. This advanced material is used in a range of applications, including aerospace, power generation, and industrial processes.

 


Forming


Nimonic PE11™ 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 should 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 PE11™ can be welded using the 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. Before the welding process begins, the surface to be welded should be cleaned and should be free from oil, paint or crayon stains.     



Heat Treatment


Nimonic PE11™ has to be solution annealed at 1021°C (1870°F) for 2 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.
