Okokuqala, kufuneka siqonde ukwakheka kweekhemikhali kunye neempawu zomzimba zeepleyiti zentsimbi engagqwali ezingama-201. Ipleyiti yentsimbi engagqwali engama-201 sisixhobo se-alloy esine-17% ukuya kwi-19% ye-chromium, i-4% ukuya kwi-6% ye-nickel kunye ne-0.15% ukuya kwi-0.25% yentsimbi yekhabhoni ephantsi. Esi sixhobo se-alloy sinokumelana okuhle nokugqwala kunye nokusebenza kobushushu obuphezulu, kwaye singasetyenziswa ixesha elide kwiindawo ezinobushushu obuphezulu kunye nezokugqwala. Ukongeza, ipleyiti yentsimbi engagqwali engama-201 ikwanokusetyenzwa kakuhle kunye namandla, anokuhlangabezana neemfuno zezicelo ezahlukeneyo zoshishino.
Okwesibini, kufuneka siqonde ukusebenza kobushushu obuphezulu kwepleyiti yentsimbi engagqwaliyo engu-201. Ngokophando olufanelekileyo, ukusebenza kobushushu obuphezulu kwepleyiti yentsimbi engagqwaliyo engu-201 kuxhomekeke kumxholo wayo we-chromium kunye nomxholo wekhabhoni. Xa umxholo we-chromium ungaphezulu kwe-10.5%, intsimbi engagqwaliyo inokumelana okuhle nobushushu obuphezulu kwaye ingasetyenziswa ixesha elide kwindawo enobushushu obuphezulu. Okukhona umxholo wekhabhoni uphantsi, kokukhona ukusebenza kobushushu obuphezulu kwentsimbi engagqwaliyo kuphezulu. Ke ngoko, ukusebenza kobushushu obuphezulu kwepleyiti yentsimbi engagqwali engu-201 kuxhomekeke kulwakhiwo lwayo oluthile lweekhemikhali kunye nenkqubo yokuvelisa.
Okokugqibela, kufuneka siqonde ukusebenza kobushushu obuphezulu kwepleyiti yentsimbi engagqwaliyo engu-201 kwizicelo ezisebenzayo. Ngokwezilingo ezifanelekileyo kunye namava okusetyenziswa, ipleyiti yentsimbi engagqwaliyo engu-201 ingasetyenziswa ixesha elide kwindawo enobushushu obuphezulu obungaphantsi kwama-500 ℃, kwaye ukusebenza kwayo kuya kwehla kancinci kwindawo enobushushu obuphezulu obungaphezulu kwama-500 ℃. Ke ngoko, xa usebenzisa iipleyiti zentsimbi engagqwali engu-201 kwiindawo ezinobushushu obuphezulu, kuyimfuneko ukukhetha kunye noyilo ngokweemfuno ezithile zesicelo kunye neemeko zokusingqongileyo.
Ngamafutshane, ipleyiti yentsimbi engagqwaliyo engu-201 sisixhobo sentsimbi engagqwaliyo esinokumelana okuhle kakhulu nobushushu obuphezulu. Ukumelana kwayo nobushushu obuphezulu kuxhomekeke kulwakhiwo lwayo oluthile lweekhemikhali kunye nenkqubo yokwenziwa kwayo, kwaye ngokubanzi ingasetyenziswa ixesha elide kwindawo enobushushu obuphezulu obungaphantsi kwama-500 °C. Kwiindlela ezisebenzayo, kufuneka ikhethwe kwaye iyilwe ngokweemfuno ezithile zesicelo kunye neemeko zokusingqongileyo ukuqinisekisa ukusebenza kwayo kubushushu obuphezulu kunye nobomi benkonzo.
