Nickel Alloy 200, UNS 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.

ASTM B163 / ASME SB163 UNS 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 B163 / ASME 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). Material 2.4066 (Nickel Alloy 200) is used in the chemical industry and petrochemical industry.
