General Information

Principal Design Features

A wrought nickel base alloy with excellent high temperature strength and oxidation resistance. It is very resistant to stress-corrosion cracking. All of the product forms are excellent in terms of forming and welding.


Applications

The alloy finds use in petrochemical process equipment and gas turbines in the hot combustor zone sections. Also used for structural components in industrial furnace applications because of the excellent oxidation resistance.


Machinability

The alloy is machinable by conventional methods and is similar to machining of the austenitic (300 series) stainless steels.


Forming

Cold working and forming of the various product forms can be done with standard tooling and processing.


Corrosion Resistance

Although this alloy is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking and has good resistance to carburization.


Welding

Welding by conventional processes such as resistance welding, shielded metal arc, and MIG or TIG can readily be done with this alloy. Matching filler metal should be used. Preheating and/or post heating are not required.


Heat Treatment

The alloy usually is supplied in the solution annealed condition. This is accomplished at 2150 F followed by a rapid cooling.


Forging

Hot forging can be accomplished by conventional practice.


Hot Working

Same as forging.


Cold Working

Readily cold worked in a manner similar to that for austenitic (300 series) stainless steels except that this alloy is somewhat "stiffer" and may require more forming pressure. After severe cold working the product can be solution annealed as indicated i


Aging

The alloy can be aged, after solution heat treatment, at temperatures of 1200 to 1600 F. Aging will result in a slight increase in strength and hardness with the effect being related to hours of exposure at the aging temperature - the longer the time the


Hardening

Hardened by cold working and somewhat by aging. This alloy is not hardenable by conventional heating an quenching as with plain carbon steels.
