45# uamea taai vevela

O le faʻaogaina o le vevela faʻapitoa mo le 45 uamea o loʻo faʻamaonia i le GB / T699-1999 tulaga masani o loʻo faʻatulagaina i le 850 ° C, faʻafefe i le 840 ° C, ma le faʻafefe i le 600 ° C. O le faʻatinoga ausia o le malosi o le gaosiga ≥355MPa
O le GB / T699-1999 faʻataʻitaʻiga o loʻo faʻamaonia ai o le malosi faʻamalosi o le 45 uʻamea o le 600MPa, o le malosi o le gaosiga o le 355MPa, o le fua faʻalauteleina o le 16%, ma le faʻaitiitia o le vaega o le 40%.
Fa'atatauga
Numera 45 uamea e masani ona faʻaaogaina i masini, pe a le faʻafefeteina: HB≤229; togafitiga vevela: masani; malosi o aafiaga: Aku≥39J; malosi maualuga, palasitika lelei ma faigata, 45 # ipu uʻamea pe a uma ona tineia e aunoa ma le faʻafefe, o le maaa e sili atu i le HRC55 (E oʻo atu i le HRC62) e agavaa. A maeʻa togafitiga vevela ma le faʻafefe, e mafai ona oʻo atu i le HRC42-46, lea e le gata ina faʻamautinoaina ana mea faʻainisinia lelei, ae maua ai foʻi manaʻoga maʻaʻa o luga. E faʻaaogaina e fai ai suiga laiti vaega e mafai ona tatalia uta tetele. O vaega lelei ma vaega lapopoa masani ma itiiti le popole, faʻapea foʻi ma vaega faʻamaʻa i luga e le manaʻomia ai le malosi maualuga, e pei o fautuaga, pou taʻiala, lima matamata ma isi vaega.
