NM 450 Abrasion Resistant Steel Phaj
NM450 yog lub siab -lub zog hnav- steel phaj nrog siab hnav tsis kam, Brinell hardness tus nqi txog li 450 (HBW) feem ntau yog siv los muab kev tiv thaiv nyob rau hauv lub sijhawm lossis qhov chaw uas yuav tsum hnav tsis kam ua kom cov cuab yeej siv tau ntev dua, txo cov txij nkawm coj los ntawm kev kho dua thiab kev poob qis, thiab raws li txo cov peev nyiaj.

NM450 abrasion resistant steel phaj Khoom Paub meej
Kev kho cua sov: kub tempering, quenching + tempering (tempering).
Daim ntawv thov: NM450 hnav- cov phaj hlau tiv taus yog dav siv hauv cov tshuab mining, thee mining machinery, environmental protection machinery, engineering machinery, etc. Nws kuj tseem siv tau los ua lub zog yield ntau dua lossis sib npaug ntawm 850MPa siab zog steel qauv.
Lub luag haujlwm: feem ntau yog xav tau kev hnav- lub sijhawm tiv taus lossis qhov chaw los muab kev tiv thaiv, kom cov khoom siv lub neej ntev dua, txo kev txij nkawm coj los ntawm kev saib xyuas lub sijhawm, thiab txo qis kev nqis peev ntawm cov nyiaj.
Khoom: tawm los nyob rau hauv ntau tshaj 950, tensile lub zog nyob rau hauv 1180 on.
