15-7PH o se semi-austenitic precipitation faʻamaʻaʻaina uʻamea uʻamea ma le malosi maualuga, maaa maualuga ma lelei tetee corrosion.O le aotelega o le corrosion teteʻe i vevela togafitia TH 1050 ma RH 950 tulaga e sili atu ona leaga nai lo tulaga masani hardenable stainless steels o le chromium-faavae 400 faasologa, ae le lelei e pei o le chromium-nickel-faavae 304 stainless steels.
PH15-7Mo (ituaiga 632) tulaga masani a le atunuu 0Cr15Ni7Mo2Al, Iapani SUS632, o se uamea ua atiina ae e ala i le suia o le 2% o le chromium i le 0Cr17Ni7Al uamea ma le 2% molybdenum.O ona uiga faʻavae e tutusa ma le 0Cr17Ni7Al sila, ae o le faʻatinoga atoa e sili atu nai lo.I le tulaga austenite, e mafai ona tetee atu i le tele o le malulu ma le faʻaogaina o faiga, ona maua ai lea o le malosi maualuga pe a uma togafitiga vevela;e sili ona lelei le vevela malosi i lalo ole 550 ℃.O loʻo faʻaaogaina i le gaosiga o vaʻalele vaʻavaʻa vaʻavaʻavaʻa vaega fausaga, pusa eseese, paipa, punavai, valve membranes, vaʻa vaʻa, compressor discs, reactor parts, ma masini vailaʻau eseese ma isi vaega faʻavae.
15-7PH Faʻatonuga Faʻafefe: O se setete, TH1050 State, RH950 State, CH900 State Tolu Faiga Faʻasaʻo vevela
Setete A: A maeʻa togafitiga fofo ile 1050°C, faʻafefe vai poʻo le ea malulu.O le fausaga metallographic o loʻo faʻaalia e austenite.
TH1050 setete: A maeʻa togafitiga fofo i le 1050 ° C, taofi i le 760 ° C ± 15 ° C mo le 90min, malulu ea, malulu i le 15 ° C poʻo le vevela o le potu i totonu o le 1h, taofi mo le 30min, ona vevela lea i le 565 ° C ± 10. °C, taofi mo le 90min i le ea, e lauiloa foi o le 565°C matua.O le fausaga metallographic o loʻo faʻaalia i le martensite faʻamaʻaina timuga.
RH950 setete: A maeʻa togafitiga fofo i le 1050 ° C, taofi i le 955 ° C ± 15 ° C mo le 10 minute, malulu i le vevela o le potu, malulu i le -73 ° C ± 6 ° C i totonu ole 24 itula, taofi mo le 8 itula, ona vevela lea i le 510 ° C ± 6 ° C, taofi mo le 60 minute i le ea-cooling, ua lauiloa foi o le 510 ℃ matua.O le fausaga metallographic o loʻo faʻaalia i le martensite faʻamaʻaina timuga.
CH900 setete: A maeʻa togafitiga fofo ile 1050 ° C, taʻavale malulu ma le 60% deformation, faʻamafanafana i le 490 ° C mo le 60min, faʻamafanafana le ea i le vevela potu.O le fausaga metallographic o loʻo faʻaalia i le martensite faʻamaʻaina timuga.
