Hlau, ib qho txawv ntawm cov hlau nrog cov pa roj carbon ntxiv, feem ntau muaj lwm cov ntsiab lus ntxiv rau nws txhawm rau npaj nws rau kev ua haujlwm thiab kev siv lag luam. Txias dov, txheej txheem nrov uas npaj cov hlau siv, ua rau cov khoom hu ua Cold Rolled Steel.
Cold Rolled Steel, feem ntau abbreviated li CR los yog CRS, yog lub npe hu ua ductile heev. Tsis tas li ntawd, nws yog formable rau nruab nrab kos daim ntaub ntawv, nrog rau tsis-shrinking thiab tsis creeping ntawm ambient kub.
Cold Rolled Steel paub txog nws lub peev xwm los tuav nruj kam rau ua thiab khaws ob peb qhov tsis zoo.
