General Information |
Principal Design Features |
This alloy of nickel-copper is resistant to sea water corrosion as well as to a variety of acids and other corrosive media. |
|
Applications |
Marine fixtures, pumps, valves and piping systems for sea water application. Because of its good corrosion resistance it is also used in chemical plant equipment. |
|
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 |
Resists corrosion from water, including sea water, and resistant to chloride stress-corrosion cracking. Good corrosion resistance to sulfuric acid, hydrochloric acid, hydrofluoric acid, and alkalis. |
|
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 |
Not heat treatable, but may be annealed after cold working. |
|
Forging |
No data, however the alloy is readily forged. |
|
Hot Working |
No data, but the alloy may be hot worked. |
|
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 1700 F. A stress-relief anneal may be done at 1050 F for 1 to 2 hours, followed by slow cooling. |
|
Hardening |
Hardens due to cold work only. |
