Ngokubanzi, i-Nickel 201 ixabiswa ngenxa yokucoceka kwayo okuphezulu, ukuchasana nokugqwesa okugqwesileyo, kunye nokuchasana nokugquma kumaqondo obushushu aphezulu. Lukhetho oluthembekileyo kumashishini ahlukeneyo apho ezi zakhiwo zifunwa.
Enye yeeyantlukwano eziphambili phakathi kwe-Nickel 200 kunye ne-Nickel 201 ngumxholo wekhabhoni. I-Nickel 201 inomlinganiselo ophezulu wekhabhoni we-0.02%, ephantsi kakhulu kunomlinganiselo ophezulu wekhabhoni we-0.15% kwi-Nickel 200. Oku kuncitshiswe umxholo wekhabhoni kwi-Nickel 201 kunika ukuchasana okuphuculweyo kwi-graphitization, inkqubo engakhokelela ekugqithiseni kunye nokunciphisa amandla. kunye nokuchasana kwempembelelo ye-alloy kumaqondo aphezulu.
Ngenxa yokucoceka kwayo okuphezulu kunye nokuxhathisa okongeziweyo kwigraphitization, i-Nickel 201 iqhele ukusetyenziswa kwizicelo ezifuna ukuvezwa kumaqondo obushushu aphezulu kunye nokunciphisa i-atmospheres. Ihlala ikhethwa ngaphezu kwe-Nickel 200 ngenxa yokukwazi ukugcina iipropati zayo zoomatshini kunye nokuchasana nokuxhamla kwiindawo ezinjalo.
I-Nickel yintsimbi eguquguqukayo kwaye esetyenziswa ngokubanzi ngenxa yeempawu zayo ezibalaseleyo, ezinjengokumelana nokugqwala, ukumelana nobushushu obuphezulu, kunye nokuhanjiswa kombane. Enye ye-nickel alloys eyaziwayo yi-Nickel 200, eyaziwa ngokucoceka kwayo kunye nokumelana nokunyuka kwe-corrosion. Nangona kunjalo, kukho enye inguqu yale alloy ebizwa ngokuba yi-Nickel 201, enokwakheka okungafaniyo kunye neepropati. Kweli nqaku, siza kuphonononga umahluko phakathi kwe-Nickel 200 kunye ne-Nickel 201 kunye nokusetyenziswa kwazo.
I-Nickel 200 yi-alloy ye-nickel ecocekileyo kunye nomxholo we-nickel ubuncinane we-99.0%. Yaziwa ngokuxhathisa kwayo okukhethekileyo kwiindawo ezonakalisayo ezahlukeneyo, kubandakanya iiasidi, izisombululo zealkaline, kunye namanzi olwandle. Oku kuyenza ibe lolona khetho lufanelekileyo kwizicelo apho ukuxhathisa umhlwa kubaluleke kakhulu, njengokusetyenzwa kweekhemikhali, ukusetyenzwa kokutya, kunye namashishini aselwandle.
