Inzuzo enkulu yokwakheka kwamakhemikhali ensimbi ye-Q450NQR1 ukuthi yenziwe ngensimbi ye-carbon evamile futhi iqukethe amanani amancane ethusi, i-nickel, nezinye izakhi ezimelana nokugqwala. Inezici zamandla ensimbi, i-ductility, ukwakha, i-welding, ukumelana nokugqoka, izinga lokushisa eliphezulu, ukukhathala nokunye; Ukumelana nesimo sezulu izikhathi ezingu-2 ~ 8 kunezinsimbi ezivamile ze-carbon, futhi ukusebenza kwe-coating kuyizikhathi ezingu-1.5 ~ 10 kune-carbon steel evamile, engasetshenziselwa ukumboza okuncane, okungenalutho noma okwenziwe lula. Insimbi inezici zokunqanda ukugqwala, ukumelana nokugqwala, impilo ende, ukunciphisa nokunciphisa ukusetshenziswa, ukonga abasebenzi nokonga amandla, okuzuzisa abakhiqizi bezingxenye nabasebenzisi.
Izici eziyinhloko zezinto ze-Q450NQR1 zibhekisela kunsimbi yesakhiwo esinengxubevange ephansi enongqimba oluvikelayo lokugqwala kanye nokumelana nokugqwala komkhathi, okungasetshenziswa ukwenza izakhiwo zensimbi njengezimoto, amabhuloho, imibhoshongo, neziqukathi. Uma kuqhathaniswa ne-carbon steel, insimbi yesimo sezulu inokumelana nokugqwala okungcono emkhathini. Uma kuqhathaniswa nensimbi engagqwali, insimbi yesimo sezulu inenani elincane kuphela lezinto eziyingxubevange, njenge-phosphorus, ithusi, i-chromium, i-nickel, i-molybdenum, i-niobium, i-vanadium, i-titanium, njll. Isamba sezinto ezihlanganisiwe zingamaphesenti ambalwa kuphela, ngokungafani ne-stainless. insimbi, efinyelela ku-100%. Amaphesenti ayishumi, ngakho intengo iphansi.
