A633 Qib A thiab A633 Qib C yog ob qho tib si siab -lub zog qis-alloy (HSLA) cov qauv hlau phaj uas tsim nyob rau hauv ib qho xwm txheej, tab sis Qib C muaj cov txiaj ntsig siab dua thiab lub zog tensile dua qib A. Qhov no txhais tau tias Qib C muaj zog dua thiab tsim nyog rau siab dua - cov ntawv siv zog siab, thaum lub zog ntawm qib 2 yog tsawg dua 9. MPa (42 ksi) piv rau Qib C qhov tsawg kawg nkaus ntawm 345 MPa (50 ksi). Ob qho tib si yog tsim los rau cov ntawv thov uas xav tau kev ua haujlwm zoo ntawm qhov kub thiab txias, xws li hauv kev tsim kho thiab sab nrauv.
