Los ntawm lub npe ntawm qhov pom, 15CrMoR yog cov hlau nrog cov ntsiab lus carbon ntawm 0.15%. Tsis tas li ntawd, chromium thiab molybdenum tshwj xeeb ntxiv rau cov hlau, ua raws li tsab ntawv R, uas txhais tau hais tias 15CrMoR steel phaj yog siv rau cov hlab ntsha siab.
15CrMoR alloy structural steel phaj yog nruab nrab kub siab txog ntsha hlau. 15CrMoR alloy structural steel daim hlau ua tau raws li tus qauv GB713, thiab tus naj npawb ntawm US steel tooj yog SA387 gr 12. 15CrMoR alloy structural steel daim hlau raug xa mus rau hauv lub xeev normalized + tempered. Cov qauv kuaj pom qhov tsis haum rau 15CrMoR alloy cov qauv hlau phaj tau ua raws li JB / T4730.3.
