NM400 yog ib hom muaj zog hnav-resistant steel phaj.NM400 muaj lub zog zoo heev, thiab nws cov khoom siv kho tshuab yog 3 mus rau 5 npaug siab dua li cov hlau tsis tshua muaj steel phaj, uas tuaj yeem txhim kho qhov hnav tsis kam ntawm cov tshuab- muaj feem xyuam nrog, yog li prolonging lub neej kev pab cuam ntawm machinery thiab txo tus nqi ntau lawm. Qhov saum npoo hardness ntawm cov khoom feem ntau ncav cuag 360 ~ 450 HB. Cov txheej txheem steel phaj yog tsim rau kev ua thiab tsim cov khoom hnav-tiv taus qhov chaw ntawm mining thiab ntau yam engineering machinery.
NM400 hnav resistant phaj Chemical Composition:
