Nimonic PE16 Bar/Tube/Pipe/Wire/Foil/Strip/Ring/Fastener

overview

NIMONIC alloy PE16 is a wrought nickel-chromiumiron-base alloy strengthened by additions of molybdenum, titanium and aluminum. It was developed for service mainly in the temperature range 500-750°C, and combines the high strength of the age hardening nickel-base alloys with excellent fabricational characteristics. The alloy is used in gas turbine flame tubes, nuclear reactor parts, missile hot components, superheater tubing, and aircraft ducting systems.

Tensile Properties of Bar

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

The heat treatment recommended for NIMONIC alloy PE16 is dependent on the intended service condition. Two are recommended, namely: (a) 4 h/1040°C/AC + 1 h/900°C/AC + 8 h/750°C/AC (b) 2 h/1040°C/AC + 2 h/800°C/AC + 16 h/700°C/AC Data shows that heat treatment (b) gives slightly higher creep-rupture properties at longer times. Heat treatment (a) gives material of greater metallurgical stablility, and is recommended for general applications. If high proof stress up to 600°C is the sole criterion then heat treatment (b) should be applied. For both the above heat treatments, the first stage at 1040°C should be for 5-15 minutes for thin section material such as sheet.
