12L14 Sa'oloto-Otioti Pa Uamea

A uʻamea faʻatasi ai ma mea e sili atu nai lo le masani o le sulfur ma le phosphorus e faʻamoemoe mo le fausiaina o vaega mo masini masini masini faʻavavevave ma semiautomatic. O le uʻamea faʻatau fua e gaosia i foliga o laʻau, ma e aofia ai le 0.08–0.45 pasene kaponi, 0.15–0.35 pasene silikoni, 0.6–1.55 pasene manganese, 0.08–0.30 pasene sulfur, ma le 0.05–0.16 pasene phosphorus. O le maualuga o le sulfur i totonu e taʻitaʻia ai le faʻavaeina o mea faʻapipiʻi (mo se faʻataʻitaʻiga, manganese sulfide) lafoai i luga o le saito. O mea fa'apipi'i e fa'afaigofie ai le seleina ma fa'aolaina le olo ma fa'afaigofie le fa'atupuina o chip. Mo nei faʻamoemoega, o nisi taimi e faʻapipiʻiina ai le sila ma le tellurium.

12L14 o se ituaiga o resulfurized ma rephosphorized carbon sila mo le tipiina saoloto ma masini talosaga. O le uʻamea faʻapipiʻi (otometi Steel) e sili ona lelei machinability ma maualalo le malosi ona o elemene faʻafefiloi e pei ole Sulfur ma Lead, lea e mafai ona faʻaitiitia ai le faʻamaʻiina ma faʻaleleia le maeʻa ma le saʻo o vaega masini. 12L14 uʻamea ua faʻaaogaina lautele i le gaosiga o meafaifaʻaili saʻo vaega, vaega taʻavale ma vaega taua o ituaiga eseese o masini, faʻaoga masani e aofia ai bushings, shafts, inserts, couplings, fittings and etc.
