NM400 /NM 450 ofuina tete'e ipu u'amea
NM450 o se ipu fa'aofuofu malosi maualuga.
Fa'aigoa: N e mo le tetee (nai), M o le mataitusi muamua pinyin o mataitusi Saina e lua mo le olo (mo),
ma le 450 o loʻo faʻatusalia le averesi Brinell maaa o lenei ipu uamea
Togafitiga vevela: faʻafefe maualuga le vevela, faʻafefe + faʻafefe (tineia ma faʻafefe)
Fa'aaogāga: NM450 fa'aofuofu u'amea fa'a'au'au fa'aoga lautele i masini eliina, masini eli koale,
masini puipuiga o le siosiomaga, masini faufale, ma isi, ma e masani ona faʻaaogaina e pei o le maualuga-malosi
uʻamea faʻavae ma le malosi e maua ai ≥850MPa.
Galuega: E masani lava e tuʻuina atu le puipuiga i taimi poʻo vaega e manaʻomia le ofuina o le tetee, ina ia ola ai
e umi le meafaigaluega, o le downtime tausiga e mafua mai i le tausiga ua faaitiitia, ma le tupe teu faafaigaluega
e tutusa foi le faaitiitia.
Faʻatinoga: O le gaosiga e sili atu i le 950, ma le malosi faʻamalosi e 1180.
NM450 e fetaui ma tulaga ese mai fafo ma togi JFE:NK-EH450/HARDOX450/DILLDUR:450V
