Baja cast kromium-molybdenum digunakake akeh ing lapangan industri kanthi sifat mekanik sing relatif dhuwur. Kajaba saka molybdenum kanggo baja kromium bisa nambah kekuatan sakacasting bajatanpa gadhah impact pinunjul ing impact kateguhan baja cast. Kajaba iku, baja cast kromium-molybdenum nduweni kinerja suhu dhuwur sing apik banget lan tahan creep. Sawise quenching lan tempering utawa normalizing perawatan panas, kromium-molybdenum cast steel bisa entuk mechanical banget.
Molybdenum bisa nambah hardenability saka cast baja lan ngurangi brittleness emosi saka cast baja. Chromium-molybdenum cast steel digunakake kanggocastings bagean gedhelan casting baja sing mbutuhake hardening jero.
