A202 Qib A Siab Hlau Phaj yog hais txog ib hom Chromium-Manganese-Silicon (Cr-Mn-Si) alloy steel phaj npog los ntawm ASTM A202 tus qauv, feem ntau yog siv rau welded boilers thiab siab hlab ntsha hauv cov roj, roj, thiab kev tsim kho dav dav rau kev tsim kho. siab - kub, siab - cov ntawv thov siab, txawm hais tias tus qauv nws tus kheej tau raug rho tawm hauv xyoo 2004 vim siv tsawg. Nws yog tus cwj pwm los ntawm cov kev txwv tshwj xeeb (xws li Cle 0.17%, Mn 1.05-1.40%, Si 0.65-0.90%) thiab cov khoom siv kho tshuab, muab lub zog zoo thiab tawv.
