General Information

Principal Design Features

This nickel-chromium-molybdenum wrought alloy is an excellent general purpose material for elevated temperature use in high strength, oxidation problem applications. It also has excellent corrosion resistance to many acids and resists intergranular attac


Applications

The alloy finds use in high temperature applications such as heat exchangers and gas turbine components. Because of its good corrosion resistance it is also used in wet scrubbers and some acid process equipment.


Machinability

May be machined by conventional means. However the alloy tends to work harden ahead of cutting and rigid tooling is essential to avoid chatter and work hardening in front of the tool edge.


Forming

This alloy can be cold formed by conventional means and tooling. The alloy does work harden during cold working with an attendant increase in strength. This increase in strength may be of value for moderate temperature applications and, in these instanc


Corrosion Resistance

This alloy has very good corrosion resistance to a wide variety of acids and chemicals. As an example it is suited for use with both hydrochloric and nitric acid. It resists chloride pitting/ crevice corrosion and chloride stress-corrosion cracking and


Welding

Welding is readily accomplished using matching alloy filler metal for the conventional welding techniques.


Heat Treatment

The alloy is furnished in the solution annealed condition. This is done at 2150 F for sufficient time dependent upon section thickness. Following the anneal the alloy may be air cooled.


Forging

Hot forging can be done by heating the billet to 2100 - 2150 F, but not over 2150. Heavy forging may then be done down to a billet temperature of 1850 F and light forging down to 1700 F. Final reductions of 15 to 20% minimum are recommended to maintain


Hot Working

Hot forming may be done by heating the alloy to 2150 F. Because this alloy is engineered for good strength at high temperatures it will resist hot deformation and therefore requires powerful equipment to perform hot forming.


Cold Working

The alloy can be cold formed by conventional methods and tooling. See also the comments under "Forming" regarding work hardening.


Annealing

Because the alloy work hardens during hot or cold forming it may be necessary to anneal such parts in order to complete forming operations. Annealing is done at 1800 to 2000 F and air cooled. Stress relief of cold worked parts may be accomplished at 110


Aging

The alloy derives its strength from its basic chemical composition. Thus aging or precipitation hardening is not applicable as a heat treatment.


Tempering

Not applicable.


Hardening

Cold working does harden the alloy and improve strength, dependent upon the amount of cold working. The alloy can be used in this higher strength cold worked condition or may be annealed at 2150 F to restore original mechanical properties.
