I-NM400 /NM 450 inxibe ipleyiti yentsimbi yokumelana
I-NM450 yipleyiti yokunxiba yamandla aphezulu.
Ukuthiywa: N yeyokumelana (nai), u-M ngunobumba wokuqala wepinyin weempawu ezimbini zesiTshayina zokusila (mo),
kunye ne-450 imele i-avareji yokuqina kwe-Brinell yale ntsimbi yentsimbi
Unyango lobushushu: ubushushu obuphezulu, ukucima + ubushushu (ukucima kunye nobushushu)
Isicelo: I-NM450 ipleyiti yentsimbi engagungqiyo isetyenziswa kakhulu koomatshini bemigodi, oomatshini bemigodi yamalahle,
oomatshini bokukhusela indalo, oomatshini bokwakha, njl., kwaye isetyenziswa ngokuqhelekileyo njengamandla aphezulu
intsimbi yolwakhiwo ngamandla isivuno ≥850MPa.
Umsebenzi: Ikakhulu kukubonelela ngokhuseleko kwiziganeko okanye iindawo ezifuna ukuxhathisa ukunxiba, ukuze ubomi be
izixhobo zinde, ixesha lolondolozo elibangelwa kulondolozo liyancitshiswa, kunye notyalo-mali lwenkunzi
iyancipha ngokufanayo.
Ukusebenza: Isivuno singaphezulu kwe-950, kwaye amandla okuqina yi-1180.
I-NM450 ihambelana nemigangatho yangaphandle kunye namabakala JFE:NK-EH450/HARDOX450/DILLDUR:450V
