● Ua matou galulue i le gaosiga o polo uamea mo le silia ma le 26 tausaga;
● Matou te ofoina atu le tele o lapopoa eseese mai le 3.175mm i le 38.1mm.Ole lapopoa e le masani ai ma fua e mafai ona gaosia i lalo ole talosaga faʻapitoa (e pei ole 5.1mm, 5.15mm, 5.2mm, 5.3mm 5.4mm mo nofoa nofoa; 14.0mm mo cam shaft ma CV sooga, ma isi);
● E tele a matou faʻasoa avanoa.O le tele o lapopoa masani (3.175mm ~ 38.1mm) ma gauges (-8 ~ + 8) o loʻo avanoa, lea e mafai ona tuʻuina vave;
● O vaega taʻitasi o polo e asiasia e masini faʻapitoa: suʻega lapotopoto, faʻataʻitaʻiga faʻataʻitaʻi, microscope suʻesuʻega metallographic, suʻega maaa (HRC ma HV) e faʻamautinoa ai le lelei.
Q: E faʻafefea ona ou filifilia le faʻailoga uʻamea talafeagai (304(L)/316(L)/420(C)/440(C))?O le a le eseesega autu i le va o le 300 ma le 400 faasologa polo uamea?
A: Ina ia filifilia le ituaiga uamea talafeagai mo polo uamea, e tatau ona tatou iloa lelei meatotino o ituaiga taʻitasi ma le faʻaogaina o polo.O polo u'amea fa'aoga masani e mafai ona vaevaeina faigofie i vaega e lua: 300 fa'asologa ma 400 fa'asologa.
300 faasologa “austenitic” polo u'amea u'amea e tele atu chromium ma nickel elemene ma le manatu e le maneta (o le mea moni e matua maualalo-mamaneta. E matua leai lava maneta e mana'omia le fa'aopoopoina o le vevela.).E masani lava e gaosia e aunoa ma le fa'aogaina o le vevela.E sili atu le malosi o le pala nai lo le 400 fa'asologa (o le mea moni, o le maualuga maualuga o le fa'afefeteina o le vaega e leai ni mea. o polo uamea u'amea eseese).E fa'aitiitia le pala, e mafai fo'i ona fa'aoga mo fa'amaufa'ailoga.400 fa'asologa o polo u'amea uamea o lo'o i ai le tele o kaponi, lea e fa'amageta ai ma sili atu le ma'a'a.E mafai ona faigofie ona togafitia e pei o polo uamea chrome poʻo polo uamea carbon e faʻateleina ai le maaa.400 faʻasologa o polo uamea e masani ona faʻaaogaina mo talosaga e manaʻomia ai le vai-tetee, malosi, maʻaʻa ma ofuina teteʻe.
