≥14% (160 <d ≤ 250mm, 100 <t ≤ 160mm)

42CrMo4+QT malo i le HRC: ≥53 (pe a maeʻa le mumu poʻo le faʻamalosi faʻamalosi)
42CrMo4 malo i le HBW: ≤255 (togafitiga ina ia fa'aleleia atili le sele); ≤241 (fa'amama vaivai)

Cuamea arbon, uamea u'amea maualalo, uamea u'amea maualuga ma uamea meafaigaluega castings o lo'o fa'aaogaina i le tele o talosaga tau alamanuia. Faatasi ai ma le tele o latou togi, uamea ma a latou u'amea e mafai ona faʻafefeteina e faʻaleleia ai lona gaosiga ma le malosi faʻamalosi ma, fetuutuunai le maaa poʻo le gaogao i manaʻoga a le inisinia poʻo mea faʻainisinia manaʻomia.

Fa'aaogaina o lefa'agasologa o tupe fa'afaigaluega, RMC casting foundry e mafai ona faʻafeiloaʻi mea faʻapitoa e tusa ai ma tulaga ASTM, SAE, AISI, ACI, DIN, EN, ISO, ma GB. E sili atu i le 100 a matou u'amea eseese ma mea e le o ni u'amea matou te lafo ai vaega e fa'aaoga ai le fa'ata'ita'iga lavelave. O a tatou mea fa'apipi'i fa'apipi'i lavelave ma fa'ata'ita'i e gaosia i foliga fa'amau, fa'aitiitia ai le mana'oga mo masini lona lua.

Chromium-molybdenum lafo uamea o loʻo faʻaaogaina lautele i fale gaosi oloa ma mea faʻainisinia maualuga. O le faʻaopoopoina o le molybdenum i le chromium steel e mafai ona faʻateleina le malosi o faʻamaʻi uʻamea e aunoa ma le i ai o se aafiaga taua i le malosi o le aʻafiaga o le sila. E le gata i lea, o le chromium-molybdenum cast steel e sili ona lelei le maualuga o le vevela ma le faʻafefe. A maeʻa ona faʻamalo ma faʻafefe poʻo faʻasaʻo togafitiga vevela, chromium-molybdenum lafo uʻamea e mafai ona maua mea sili ona lelei masini.

E mafai e le Molybdenum ona faʻaleleia le faʻamalosi o le uamea lafo ma faʻaitiitia le faʻafefe o le ita o le sila. Chromium-molybdenum lafo uamea o loʻo faʻaaogaina mo le tele o vaega faʻapipiʻi ma uʻamea e manaʻomia ai le faʻamaʻaina loloto.
