Nickel 200 (UNS N02200) na 201 (UNS N02201) bụ ihe nickel arụrụ n'ụkwụ abụọ. Ha dị iche naanị na ọkwa carbon kachasị dị ugbu a - 0.15% maka Nickel 200 na 0.02% maka Nickel 201.
A na-ejedebe efere Nickel 200 na ọrụ na okpomọkụ n'okpuru 600ºF (315ºC), ebe ọ bụ na okpomọkụ dị elu ọ nwere ike ịta ahụhụ site na graphitization nke nwere ike imebi ihe onwunwe. N'oge okpomọkụ dị elu, ekwesịrị iji efere Nickel 201 mee ihe. A kwadoro akara ule abụọ n'okpuru ASME Boiler na Pressure Vessel Code Nkebi nke VIII, Nkeji 1. A kwadoro efere Nickel 200 maka ọrụ ruo 600ºF (315ºC), ebe a kwadoro efere Nickel 201 ruo 1250ºF (677ºC).
Klas abụọ a na-enye nguzogide corrosion pụtara ìhè na soda caustic na alkalis ndị ọzọ. Alloys na-arụ ọrụ kacha mma n'ibelata gburugburu mana enwere ike iji ya n'okpuru ọnọdụ oxidizing nke na-emepụta ihe nkiri oxide na-agafe agafe. Ha abụọ na-eguzogide corrosion site na distilled, mmiri eke na mmiri oké osimiri na-eru, mana mmiri mmiri na-adịghị akwụsị akwụsị na-awakpo ha.
Nickel 200 na 201 bụ ferromagnetic ma na-egosiputa ihe eji arụ ọrụ nke ukwuu n'ofe oke okpomọkụ.
A na-agbaji ma hazie akara ule abụọ ahụ n'ụzọ dị mfe site na usoro nrụpụta ụlọ ahịa ọkọlọtọ.
