Nimonic PK33/ SAE AMS 5829; AECMA Pr EN 2295 Strip Sheet bar

overview

Alloy PK33 is a superalloy which is highly resistant to thermal shock and thermal fatigue. It is a vacuum processed nickelbase alloy that was developed to provide a sheet

material offering improved ductility in welded

assemblies and high creep strength to replace

NIMONIC alloys 80A and 90

Alloy PK33 also offers superb weldability, is often used in high strength applications at elevated temperatures, such as in gas turbine hot sections or enclosures for industrial furnace hot sections.

Physical Constants

Below are some physical constants and thermal properties of

Mechanical properties

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 PE16™ 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.   

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.
