12MnNiVR yog steel phaj rau cov hlab ntsha siab. Piv nrog rau SPV490Q tawg rhiab heev coefficient Pcm nyob rau hauv lub Japanese standard JIS G3115, nws yog qis dua thiab ntau conducive rau steel phaj vuam. Kev coj ua piv txwv ntawm qhov kev ntsuam xyuas qhov cuam tshuam yog hloov los ntawm qhov ntev mus rau transverse, thiab qhov cuam tshuam qhov kub thiab txias tau hloov ntawm -10 degrees mus rau - 15 degrees lossis qis dua, thiab qhov cuam tshuam lub zog tau txhim kho. 12MnNiVR yog siv hauv kev tsim cov roj tank loj.
