AISI 420 Fa'amea u'amea u'amea
Fa'amatalaga Puupuu:
420 Fa'amea u'amea u'amea Strip o se ituaiga o u'amea u'amea fasi ua mamanuina faapitoa mo talosaga tautotogo. 420 fasi uamea uamea ofoina atu corrosion tetee lelei, faia e talafeagai mo talosaga i environments eseese.420 fasi uamea uamea faaalia uiga tautotogo sili ona lelei, e aofia ai elasticity lelei, maufetuunaʻi maualuga, ma le mafai ona toe foi i lona foliga muamua pe a uma deformation.
