I-Nickel 200 (UNS N02200) ne-201 (UNS N02201)

I-Nickel 200 (UNS N02200) kanye ne-201 (UNS N02201) ayizinto ezikhandwayo eziqinisekiswa kabili. Ahluka kuphela emazingeni aphezulu ekhabhoni akhona—u-0.15% ku-Nickel 200 no-0.02% ku-Nickel 201.

Ipuleti le-nickel 200 livamise ukukhawulelwa ekusebenzeni emazingeni okushisa angaphansi kuka-600ºF (315ºC), njengoba emazingeni okushisa aphakeme lingahlushwa i-graphitization engonakalisa kakhulu izakhiwo. Emazingeni okushisa aphezulu kufanele kusetshenziswe ipuleti le-Nickel 201. Womabili amamaki agunyazwe ngaphansi kwe-ASME Boiler ne-Pressure Vessel Code Section VIII, Division 1. Ipuleti le-Nickel 200 ligunyazelwe isevisi efika ku-600ºF (315ºC), kuyilapho ipuleti le-Nickel 201 ligunyazwe kufika ku-1250ºF (677ºC).

Womabili amamaki anikeza ukumelana nokugqwala okuvelele ku-caustic soda namanye ama-alkali. Ama-alloys enza kahle kakhulu ekunciphiseni izindawo kodwa angasetshenziswa ngaphansi kwezimo ze-oxidizing ezikhiqiza ifilimu ye-oxide ye-passive. Zombili zimelana nokugqwala ngamanzi acwecwe, amanzi emvelo kanye namanzi olwandle agelezayo kodwa zihlaselwa amanzi olwandle amile.

I-Nickel 200 kanye ne-201 ziyi-ferromagnetic futhi zibonisa izakhiwo zemishini ezidonsa kakhulu endaweni yokushisa ebanzi.

Womabili amabanga ashiselwa kalula futhi acutshungulwa ngezinqubo ezijwayelekile zokwenziwa kwezitolo.
