General Information Principal Design Features This is a high-strength, high-temperature resistant and corrosion resistant nickel-chromium alloy. It is suitable for use at cryogenic temperatures and also for use in air up to 1300 F. The alloy is readily worked and can be age-hardened. Applications Applications include gas turbine hot section components and cryogenic storage tanks. 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 This alloy is resistant to corrosion from organic acids and also resists attack by many acids. It is especially 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 The alloy is age-hardenable (see under "Aging") and can be annealed at 1900 F followed by air cooling. Forging Forging is done in the range of 2050 F to 1700 F. Final reductions of 20% for open die work and 10% for closed die are desired to maintain proper grain structure and finishing temperatures should be in the 1750 F - 1700 F range. Hot Working Hot working may be done in the temperature range of 2050 F to 1650 F. It is important to reheat the alloy if hot working temperatures fall below 1650 F. 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 may be done at 1900 F followed by rapid air cooling. Aging Two slightly different aging heat treatments are available. 1. 1800 F anneal and age at 1325 F for 8 hours, then furnace cool to 1150 F and hold at that temperature for 10 hours, then air cool. This is the optimum treatment for the highest room temp Hardening Cold work will cause an increase in both hardness and strength. The alloy may also be age-hardened -- see "Heat Treat".
