General Information

Principal Design Features

A nickel-chromium precipitation-hardening alloy suited for high strength at temperatures above 1300 F, with useful strength up to 1800 F. The alloy is also has excellent properties and ductility at cryogenic temperatures.


Applications

Structural members in hot sections of gas turbines such as discs, thrust reversers and ducts. Heat treat fixtures and cryogenic vessels, springs and fasteners.


Machinability

Conventional machining techniques used for iron based alloys may be used. This alloy does work-harden during machining and has higher strength and "gumminess" not typical of steels. Heavy duty machining equipment and tooling should be used to minimize c


Forming

This alloy has good ductility and may be readily formed by all conventional methods. Because the alloy is stronger than regular steel it requires more powerful equipment to accomplish forming. Heavy-duty lubricants should be used during cold forming. I


Corrosion Resistance

As is true for all of the high content nickel-chromium alloys the corrosion resistance of this alloy is good for both oxidizing and reducing environments found in many industrial applications. It is highly resistant to chloride stress-corrosion cracking.


Welding

The commonly used welding methods work well with this alloy. Matching alloy filler metal should be used. If matching alloy is not available then the nearest alloy richer in the essential chemistry (Ni, Co, Cr, Mo) should be used. All weld beads should


Heat Treatment

A variety of heat treatments are available for this alloy depending upon the end result properties that are to be optimized. All involve a solution anneal at temperatures in the 1625 F to 2100 F range and then a single or double precipitation-treating ti


Forging

Forging may be readily accomplished in the temperature range of 2200 F to 1900 F. Light forging for finishing can be done in the 1900 F - 1800 F range, below 1800 F the alloy is very stiff and may crack.


Hot Working

Hot working should be accomplished in the temperature range of 2200 F to 1800 F. The final hot reduction should be 20% at a temperature less than 2000 F, but above 1800 F in order to meet specification properties.


Cold Working

Cold forming may be done using standard tooling although plain carbon tool steels are not recommended for forming as they tend to produce galling. Soft die materials (bronze, zinc alloys, etc.) minimize galling and produce good finishes, but die life is


Annealing

Annealing from cold worked condition can be done at 1800 F to 2000 F followed by air cooling. This is to anneal the alloy only and not a final form heat treatment.
