General Information Principal Design Features This is an age-hardenable alloy of nickel-chromium-iron. The additions of titanium and aluminum enable it to be age-hardened while molybdenum and copper contents enhance resistance to corrosive media. Designed primarily for applications in the production Applications It is used in the petroleum industry for applications such as gas well components, valves and tubing, as well as finding use in high-strength piping systems. 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 The alloy is highly resistant to a wide variety of corrosive media. It resists pitting, intergranular corrosion, general corrosion, and stress-corrosion cracking. It is an ideal material for use in natural gas production when hydrogen sulfide (sour gas) 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 Solution anneal at 1900 F to 1800 F and air cool. Aging is done at 1350 F for 8 hours, furnace cool at 75 F per hour down to 1175 F and hold at 1175 F for at least 12 hours then air cool. Forging Forging should be done in the range of 2150 F to 1700 F. Hot Working Hot working may be done in the range of 1800 F down to 1600 F. Avoid working at temperatures above 1800 F to retain corrosion resistance. 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 Anneal at 1850 F for at least 2 hours at temperature, air cool. Aging See "Heat Treat". Hardening May be hardened by heat treatment - see "Heat Treat" and also hardens due to cold working. Physical Data
