O le uamea faʻamaʻaʻaina o timuga, e taʻua o le PH Steel, e faʻatatau i le ituaigaapa silivalea e faaopoopo ai ituaiga eseese ma le tele o elemene faamalosia, ma ituaiga eseese ma aofaiga o carbide, nitride, carbonitrides ma intermetallic compounds e faʻafefeteina e ala i le faʻamaʻaina o timuga. O le faʻamaʻaina o timuga e le gata ina maualuga le malosi, ae o loʻo i ai foi le malosi lelei ma le faʻafefeteina. O le u'amea fa'ama'a'aina uamea e mafai ona lafo ia tatoufa'amea fa'amea fa'afaigaluegae tusa ai ma au ata, mana'oga ma tulaga fa'aoga.
E tusa ai ma mea o loʻo i totonu o elemene faʻapipiʻi autu i le faʻamaʻaina o le uʻamea faʻamaʻaʻaina ma le faʻaopoopoina o mea faʻamalosi, e mafai ona vaevaeina le uamea faʻamaʻaina o timuga i ni vaega se fa i mea nei:
(1)Martensitic Precipitation Fa'ama'a'aina u'amea. E masani ona iai le carbon i lalo ifo o le 0.1%. Faʻamalosia e ala i le faʻaopoopoina o elemene faʻamalosi (apa, alumini, titanium ma alumini, ma isi) e faʻaleleia ai le leai o se malosi. Ole mea ole chromium e masani ona maualuga atu nai lo le 17%, ma o se aofaiga talafeagai ole nickel e faʻaopoopoina e faʻaleleia ai le faʻafefeteina.
(2)Maraging Timuga Fa'ama'a'aina u'amea, faʻatasi ai ma le carbon content e le sili atu nai lo le 0.03% e faʻamautinoa ai le malosi, faʻafefeteina, faʻamalosia ma le faʻaogaina o le martensite matrix, ma le 12% chromium e faʻamautinoa ai le faʻafefe. E le gata i lea, ua faʻaopoopoina le cobalt elemene elemene e faʻaleleia atili ai le faʻaogaina o le vevela o le sila.
(3)Semi-Austenitic Precipitation Fa'ama'a'aina u'amea, o lona uiga, fa'afefete fa'afefeteina fa'ama'a'aina u'amea, o lo'o i ai le itiiti ifo i le 12% chromium. E maualalo le kaponi anotusi, ma alumini e fai ma ona elemene faʻamaʻaina timuga autu. O lenei ituaiga o timuga fa'ama'a'aina uamea uamea e sili atu lona fa'atinoina nai lo le martensitic precipitation hardening stainless steel.
(4)Austenitic Precipitation Fa'ama'a'aina u'ameao se uamea stainless ma fausaga austenite mautu i setete uma tineia ma le matua. O lona anotusi nickel ma le manganese e maualuga, ma o le chromium e maualuga atu nai lo le 13% e faʻamautinoa ai le lelei o le pala ma le faʻamaʻiina. I le taimi lava e tasi, o le austenitic precipitation hardening stainless steel e masani ona faaopoopo i ai le titanium, alumini, vanadium poʻo le phosphorus e avea ma elemene faʻamaʻaina o timuga, ma faʻaopoopoina se vaega itiiti o le boron, vanadium, nitrogen ma isi elemene e maua ai mea lelei atoatoa.
O le uamea faʻamaʻaʻaina o timuga o loʻo faʻaaogaina lautele i fale gaosi oloa. Mo se faʻataʻitaʻiga, e mafai ona faʻaogaina le uʻamea faʻamaʻaʻaina 17-4PH e fai ai fausaga i lalo ifo o le 370 ° C e manaʻomia ai le faʻafefeteina, faʻaofuofu teteʻe, ma le malosi maualuga.
