Nickel Alloy 200 N02200 DIN 17751 2.4066 NA11 Ni 99,2 are solid solution strengthened, commercially pure wrought materials with good mechanical properties over a wide range of temperature and excellent corrosion resistance, in particular hydroxides. Nickel 201 was a modification of 200 to control carbon (.02 max) which keeps it from being embrittled by intergranular precipitate at temperature of 600° F to 1400° F. Typically, the elemental restrictions of both, Nickel Alloy 200 and nickel 201, dual-certified chemistry resulting in a single alloy with the desired characteristics of both alloys. 2.4066 Equal to Nickel Alloy 200.
Both ASTM B161 ASME SB 161 N02200 Alloy 200 and 201 offer corrosion resistance in reducing and neutral media as well as in oxidizing atmospheres provided that the oxidizing media allows the formation of a passive oxide film. This oxide film accounts for the materials excellent resistance in caustic environments. Corrosion rates in both marine and rural atmospheres are very low.
The resistance of ASTM B161 B163 ASME SB161 SB163 N02200 to corrosion by distilled and natural waters is excellent. Plus it also gives excellent service in flowing sea water even at high velocity, but in stagnant or very low-velocity seawater severe local attack may occur under fouling organisms or other deposits. In hot water systems where the steam contains carbon dioxide and air in certain proportions, corrosion rates will be initially high but will decrease with time if conditions favor the formation of a protective film.

ASTM B161 B163 ASME SB161 SB163 N02200 is normally limited to service at temperatures below 600 °F. At higher temperature Nickel Alloy 200 products can suffer from graphitization which can result in severely compromised properties. When operating temperatures are expected to exceed 600° F, carbon content becomes critical. The lower carbon content of Nickel 201 makes the material resistant to graphitization and therefore less subject to embrittlement. Nickel Alloy 200 & 201 are approved for construction of pressure vessels and components under ASME Boiler and Pressure Vessel Code Section VIII, Division 1. Nickel Alloy 200 is approved for service up to 600 °F while Nickel 201 is approved for service up to 1230 °F. Melting point is 2615-2635 °F.
ASTM B161 B163 ASME SB161 SB163 N02200 is unalloyed nickel with excellent corrosion resistance and excellent stability against alkaline media and good mechanical properties in a broad temperature range. Shows good corrosion resistance under reducing conditions, e.g. hydrofluoric acid and hydrochloric acid. Shows good stability under oxidizing conditions (by creating a surface protection film).
