O le a le AISI 5140 uamea?
ASTM grade 5140 o se tasi u'amea u'amea u'amea vasega i le ASTM A29 tulaga mo le fa'aoga lautele. 5140 ipu uʻamea lautele faʻaaogaina i vaega maualalo ma moderately faamamafaina mo taavale, afi ma masini e faigata, ofuina tetee luga e manaomia. O le Gnee o le fa'apolofesa 5140 ipu ma le pa'u fa'apolofesa fa'apolofesa ma matou te fa'atumauina le tele o lapo'a mo le 5140 ipu i fa'atau mo le uta vave. Faʻafesoʻotaʻi matou mo soʻo se talosaga AISI 5140 ipu meamea ma sili 5140 tau vasega uʻamea.
Manuia Faatauva mo AISI 5140 meamea ipu uamea i Otai:
- E maua i fa'asoa mo le uta vave
- Malosi maualuga,
- Malosi maualuga
- Malo maaa lelei
