Okwamanje emakethe yaseShayina yokuthengisa yeinsimbi engagqwaliikakhulukazi iwuchungechunge lwama-300 nochungechunge lwama-200, umehluko phakathi kwakho kokubili inani le-chemical element ye-nickel okuqukethwe, okubangele ekusebenzeni kanye nentengo yomehluko omkhulu.
Ezingeni lamanje lamanani e-nickel, okuqukethwe kwe-nickel kuphansi kakhulu kwentengo ye-200 ye-stainless steel cishe ingxenye yochungechunge lwama-300 lwensimbi engagqwali, ukugqwala kanye nokuqina ekusebenzeni kwentwasahlobo kubi kakhulu kunochungechunge lwama-300.insimbi engagqwali, esebenza kuphela ekucubunguleni ukudla kwekhabhinethi kanye nezinye izinkambu, uma isetshenziselwa ukwakhiwa, imishini yezokwelapha, insimu yebhasikidi, kuyoba nenkinga enkulu efihliwe.Okuqukethwe kwe-nickel cishe okungu-1% kwemikhiqizo engu-200 yochungechunge, akukwazi ukugqwala okuvamile komkhathi.
300 uchungechunge lwensimbi engagqwaliyaziwa nangokuthi i-18-8 steel, izinsimbi, amalunga, amashubhu namapayipi izinto ezisetshenziswa kakhulu.Insimbi engu-18-8 ingukuqukethwe okuzisholo kwe-chromium ne-nickel ochungechungeni lwensimbi engagqwali engama-300, lezi zinto ezisebusweni bokumelana nokugqwala okuhle, kodwa ngenxa yokubekwa kwekhabhoni, kuzokwenza okuqukethwe kwe-chromium kwehle.I-Chromium ihlangana nekhabhoni emazingeni okushisa aphezulu ukuze yakhe i-chromium carbide, engamelani nokugqwala.
400 uchungechunge lwensimbi engagqwali okuqukethwe chromium kuka300 uchungechunge lwensimbi engagqwaliokuphansi, kodwa akufani nochungechunge lwama-300 olunezinkinga zokubeka i-carbon, futhi lungelashwa ngokushisa, kodwa ngenxa yokuqukethwe kwe-chromium okungu-12% kuphela kwe-14%, endaweni yomoya onzima wamakhemikhali uzogqwala ukusetshenziswa kochungechunge lwama-300 oluqukethe i-16. Amaphesenti angu-20 e-chromium, ngeke agle.300 uchungechunge lwensimbi engagqwali kanye 400 uchungechunge insimbi engagqwali ngamandla afanayo.
