Njengamanje ekuthengisweni kwemakethe yaseChina kweinsimbi engagqwaliIyindlela engu-300 uchungechunge nochungechunge olungu-200, umehluko phakathi kwalezi ezimbili inani lokuqukethwe kwe-chemic element, okwabadale ekusebenzeni nasekubizweni komehluko omkhulu.
Ezingeni lamanje lamanani entengo ye-nickel, okuqukethwe kwe-nickel kuphansi kakhulu uchungechunge lwensimbi engangemibili engu-200 kungemuva kwengxenye yensimbi engu-300 kuphela, ukugqwala kanye nobunzima ekusebenzeni kwentwasahlobo kubi kakhulu kunochungechunge lwama-300insimbi engagqwali, kusebenza kuphela ekusebenzeni kokudla kweKhabhinethi kanye nezinye izinkambu, uma kusetshenziswe ekwakhiweni, emishini yezokwelapha, insimu yebhasikidi, kuzoba nenkinga enkulu efihlekile. Okuqukethwe kwe-nickel okungaba ngu-1% wemikhiqizo yochungechunge engama-200, akunakubekwa ngaphansi kokugqwala komoya okujwayelekile.
300 Series insimbi engagqwaliYaziwa nangokuthi yi-18-8 yensimbi, ingabe ama-fasteners, amalunga, amashubhu namapayipi izinto ezisetshenziswa kakhulu. I-18-8 I-Steel yiyona ehlukile yokuqukethwe kwe-chromium ne-nickel ngochungechunge lwensimbi engu-300, lezi zinto zokwakha ngaphezulu kokumelana kahle, kodwa ngenxa yokuqukethwe kwekhabhoni, kuzokwenza ukuthi okuqukethwe kwe-chromium ukwehla. I-Chromium ihlanganisa ngekhabhoni emazingeni okushisa aphezulu ukwakha i-chromium carbide, okungeyona eyokukhuthaka.
400 uchungechunge lwensimbi yensimbi engagqwali ngaphandle300 Series insimbi engagqwaliOkuphansi, kepha akufani nochungechunge lwama-300 anezinkinga ze-carbon desition, futhi kungalashwa ukushisa, kepha ngenxa yokuqukethwe kwe-chromium kuphela, endaweni eyi-14% kuphela equkethe i-16% yama-20% we-chromium, ngeke ihluleke. I-300 Series insimbi engenacala nochungechunge lwe-400 lwensimbi engenacala ngamandla afanayo.
