60kg / m U75V cov khoom yog tus qauv tsim nyog rau GB siab-nrawm rail. U75v yog cov pa roj carbon hlau siab. Piv nrog rau cov dav dav-laj thawj carbon steel u71mn cov khoom siv tau ua kom muaj kev ua haujlwm hnyav ua rau muaj zog, hardness thiab thauj-kabmob. Nyob rau tib lub sijhawm, cov khoom siv U75V kuj tseem ua rau kev soj ntsuam vuam ntawm lub rail hnyav dua thiab ua kom muaj vuam zoo. Kev siv ntawm kub dov thev naus laus zis tau zoo heev txhim kho cov tawv, hnav tsis kam thiab lwm yam khoom siv ntawm kev tsheb nqaj hlau.
