Mae gan bibell ddur aloi ASTM A213 sefydlogrwydd thermol da, ymwrthedd ocsideiddio, ymwrthedd cyrydiad, cryfder uchel, caledwch uchel a nodweddion eraill. Gall weithredu'n sefydlog am amser hir mewn amgylcheddau gwaith tymheredd uchel a phwysau uchel. Fe'i defnyddir yn eang mewn petrolewm, diwydiant cemegol, pŵer trydan, a boeleri. , hedfan, awyrofod a meysydd eraill.
