General Information

Principal Design Features

A nickel-chromium-iron alloy with excellent resistance to high temperature oxidation. A general purpose material for applications where heat and corrosion resistance are the primary considerations.


Applications

A construction alloy for heat treat furnace fixtures and components such as annealing tubes, muffles, flame shields. Also useful for chemical process equipment such as combustor components, process heaters, and condenser tubes.


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 ch


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 has good corrosion resistance to nitric acid and to low concentrations of phosphoric acid. It does not resist hydrochloric, sulfuric, or hydrofluoric acids. Resistance to attack by sodium hydroxide solutions is good. The alloy is also very


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 not hardened or strengthened by heat treatment.


Forging

Forging should be done in the temperature range of 2250 F to 1900 F.


Hot Working

Hot work in the range of 2250 F to 1600 F. Avoid working in the range of 1400 F to 1000 F as the alloy is apt to thermal crack in that region.


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 following cold working may be necessary. The annealing temperature is 2100 F and the alloy should be rapidly cooled through the range of 1400 to 1000 F to avoid thermal cracking.


Hardening

The alloy hardens by cold working only.
