Imvula eyenza insimbi engagqwali ibe lukhuni, ebizwa nge-PH Steel, ibhekisela ohlotsheni lweinsimbi engagqwaliokwengeza izinhlobo ezahlukene kanye nenani lezinto eziqinisayo, futhi izinhlobo ezahlukene nenani lama-carbides, ama-nitrides, ama-carbonitrides nama-intermetallic compounds ancishiswa ngenqubo yokuqina kwemvula. Imvula eyenza insimbi engagqwali ibe lukhuni ayigcini nje ngokuba namandla aphezulu, kodwa futhi inokuqina okuhle nokumelana nokugqwala. Imvula eqinisa insimbi engagqwali ingaphonswa kithiisisekelo sokutshala imalingokwemidwebo yakho, izidingo kanye nesimo sokusebenzisa.
Ngokokuqukethwe kwezakhi eziyinhloko zengxubevange emvuleni eqinisa insimbi engagqwali kanye nezinto ezengeziwe eziqinisayo, insimbi eqinile eqinile ingahlukaniswa izigaba ezine kulokhu okulandelayo:
(1)I-Martensitic Precipitation Iqinisa Insimbi Engagqwali. Ngokuvamile iqukethe ikhabhoni ngaphansi kuka-0.1%. Qinisa ngokungeza izakhi eziqinisayo (ithusi, i-aluminium, i-titanium ne-aluminium, njll.) ukuze wenze ukuntuleka kwamandla. Okuqukethwe kwe-chromium ngokuvamile kuphezulu kuno-17%, futhi inani elifanele le-nickel liyangezwa ukuze kuthuthukiswe ukumelana nokugqwala.
(2)Imvula Enyakazayo Iqinisa Insimbi Engagqwali, enokuqukethwe kwekhabhoni engengaphezulu kuka-0.03% ukuze kuqinisekiswe ukuqina, ukumelana nokugqwala, ukushisela nokusebenza kwe-matrix ye-martensite, kanye ne-chromium engu-12% yokuqinisekisa ukumelana nokugqwala. Ngaphezu kwalokho, i-cobalt ye-alloy element yengezwa ukuze kuthuthukiswe umphumela wokwelapha ukushisa kwensimbi.
(3)I-Semi-Austenitic Precipitation Eqinisa Insimbi Engagqwali, okungukuthi, imvula eshintshayo yenza lukhuni insimbi engagqwali, equkethe i-chromium engekho ngaphansi kuka-12%. Inokuqukethwe kwekhabhoni ephansi, kanye ne-aluminium njengento eyinhloko eqinisa imvula. Lolu hlobo lwezulu oluqinisa insimbi engagqwali lusebenza kangcono kunemvula ye-martensitic eqinisa insimbi engagqwali.
(4)I-Austenitic Precipitation Eqinisa Insimbi Engagqwaliiyinsimbi engagqwali enesakhiwo esizinzile se-austenite kuzo zombili izifunda ezicishiwe neziguga. Okuqukethwe kwayo kwe-nickel nokuqukethwe kwe-manganese kuphezulu, futhi okuqukethwe kwe-chromium kungaphezu kuka-13% ukuze kuqinisekiswe ukumelana nokugqwala okuhle nokumelana ne-oxidation. Ngesikhathi esifanayo, i-austenitic precipitation eyenza lukhuni insimbi engagqwali ngokuvamile yengeza i-titanium, i-aluminium, i-vanadium noma i-phosphorus njengezakhi eziqinisa imvula, futhi yengeze inani elincane le-boron, i-vanadium, i-nitrogen nezinye izakhi ukuze kutholwe izakhiwo ezinhle kakhulu ezibanzi.
Imvula eyenza insimbi engagqwali ibe lukhuni isetshenziswa kakhulu ezimbonini ezithuthukile. Isibonelo, imvula evamile eyenza insimbi engagqwali ibe lukhuni engu-17-4PH ingasetshenziswa ukwenza izakhiwo ezingaphansi kuka-370°C ezidinga ukumelana nokugqwala, ukumelana nokuguga, namandla aphezulu.
