SA662 Qib B thiab C yog ASME-spec carbon-manganese-silicon steel daim hlau rau nruab nrab mus rau qis- cov hlab ntsha kub siab, sib txawv hauv cov qib siab zog (Qib C muaj zog dua) thiab ua tiav; Qib C feem ntau yuav tsum tau ua kom zoo dua qub rau kev ua kom zoo dua qub, thaum Qib B muaj kev sib txuas zoo rau kev tsim khoom, ob qho tib si ua haujlwm zoo xws li boilers thiab tanks.

Xav txog lawv raws li qhov sib txawv ntawm lub zog sib txawv rau tib hom kev ua haujlwm (cov hlab ntsha siab). Qib B yog qhov zoo tag nrho - rounder, thaum Qib C muaj zog dua thiab tawv rau cov ntawv thov ntau dua, ua tiav los ntawm kev ua haujlwm nruj dua li normalization.
