13MnNiMoR yog steel phaj rau nruab nrab thiab qis kub siab cov hlab ntsha. Lub ntsiab lus "R" hauv qib yog hais txog thawj tsab ntawv ntawm tus pinyin ntawm "muaj peev xwm" ntawm lub nkoj siab. 13 qhia tias cov ntsiab lus carbon yog 0.13%. Mn, Ni, thiab Mo hauv qib sawv cev rau cov tshuaj manganese, npib tsib xee, cov ntsiab lus ntawm molybdenum kuj siab, thiab 13MnNiMoR muaj cov khoom tshwj xeeb thiab cov khoom, thiab feem ntau yog siv hauv cov hlab ntsha siab.
