The Nickel 200 alloy is commercially pure wrought Nickel and has good mechanical properties that extend over a wide range of temperatures. The Nickel 200 alloy, also known as ni200, has excellent resistance to many corrosives, hydroxides in particular.

Nickel 200 has native properties to provide strong resistance to corrosion in acids and alkalis. It is especially useful under reducing conditions. The alloy has outstanding resistance to caustic alkalis, which includes its molten state. The alloy shows good resistance in acid, alkaline, and neutral salt solutions. However, in oxidizing salt solutions severe corrosion will occur. The Nickel 200 alloy is resistant to all dry gases at room temperature. In dry chlorine and hydrogen chloride, nickel alloy 200 may be used in temperatures up to 550C. Its resistance to mineral acids varies according to temperature, concentration, and solution aeration. Its corrosion resistance displays better in de-aerated acid.

Machining

Nickel and cobalt based alloys can be difficult to machinine. However, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates. These alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. The following are key points which should be considered during machining operations:

CAPACITY - Machine should be rigid and overpowered as much as possible.
RIGIDITY - Work piece and tool should be held rigid. Minimize tool overhang.
TOOL SHARPNESS - Make sure tools are sharp at all times. Change to sharpened tools at regular intervals rather than out of necessity. A 0.015 inch wear land is considered a dull tool.
TOOLS - Use positive rake angle tools for most machining operations. Negative rake angle tools can be considered for intermittent cuts and heavy stock removal. Carbide-tipped tools are suggested for most applications. High speed tools can be used, with lower production rates, and are often recommended for intermittent cuts.
POSITIVE CUTS - Use heavy, constant, feeds to maintain positive cutting action. If feed slows and the tool dwells in the cut, work hardening occurs, tool life deteriorates and close tolerances are impossible.
LUBRICATION - lubricants are desirable. Soluble oils are recommended especially when using carbide tooling.
