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 fa'amea fa'apitoa mo talosaga tautotogo.420 fasi uamea uamea ofoina atu corrosion tetee lelei, e talafeagai mo talosaga i environments eseese.420 fasi uamea uamea faaalia uiga tautotogo lelei, e aofia ai elasticity lelei, maufetuunaʻi maualuga, ma le mafai ona toe foi i lona foliga muamua pe a uma deformation.
