Fa'ailogae masani lavafa'ailogainamulimuli anefa'ameamea, tipiina, faʻafefeteina ma isi faiga.Ina ia faʻamautinoa le lelei o le gaosiga o le mate ma faʻaitiitia le tau o le gaosiga, e tatau ona i ai i le meafaitino lelei le malleability, machinability, hardenability, hardenability ma grindability;E tatau foi ona i ai se laʻititi laʻititi i le faʻamaʻiina, decarburization ma tineia deformation ma taʻe.
1, faigofie:e maualalo le vevelafa'ameameatete'e deformation, palasitika lelei, forging tulaga vevela e lautele, forging ta'e malulu ma timuga carbide mateletelega e maualalo.
2, fa'agasologa o fa'ama'i:spheroidizing fa'afefete fa'afefete e lautele lautele, fa'afefe ma'a'a e maualalo ma fela'ua'iga va'aiga laiti, spheroidizing fua faatatau e maualuga.
3, tipiina machinability:tele tipi tipi, maualalo meafaigaluega gau, machining maualalo roughness luga.
4, oxidation, decarburization lagona:vevela vevela maualuga, oxidation teteʻe e mafai ona lelei, decarburization saoasaoa e telegese, e le maaleale i le auala faamafanafana, o le gaosiga o le pitting uiga e laiti.
5, malosi:ina ua uma ona tineia, o loʻo i ai toniga ma maualuga maaa luga.
6, Malosi:a maeʻa ona tineia, e mafai ona maua se faʻamaʻaʻaina loloto atu, ma e mafai ona faʻamaʻaʻaina le ala faʻafefete i le faʻafefeteina feololo.
7, tineia deformation ta'e uiga:e la'ititi le suiga o le voluma tineia masani, fa'a'ave'esea foliga, e la'ititi le fa'alavelave, e la'ititi le fa'alavelave fa'aletonu.tineia masani e maualalo le maaleale ta'e ma e le maaleale i le tineia vevela ma mea faigaluega foliga.
8, Malosi:e la'ititi le pa'u o le uili olo, e leai se fa'atapula'aina o le mu e tele le aofa'i o le olo, e le ma'ale'ale le tulaga lelei o le uili ma le malulu, e le faigofie ona ofuina mea leaga ma olo.
