12Cr1MoV faagaau fauvela maualuga maualugana atiina ae mai le uʻamea muamua 12xm (0.5% Cr-Mo-V) i le 12x1m (1% Cr-Mo-V) uamea e ala i le faʻateleina o le Cr anotusi.Le tuufaatasiga o vailaau o12Cr1MoV Alloy Fa'apa'u Uamea Su'esu'ee faigofie, o le aofaʻi o mea faʻapipiʻi e itiiti ifo i le 2%, ma o loʻo i ai se gaioiga sili ona lelei ma mea faʻaletino.I le taimi nei, o loʻo lisiina i totonu o le faʻamaualuga paipa uamea mo le faʻavevela maualuga i Saina (GB5310-2008).Fa'ailoga uamea tutusa fa'aaoga lautele i fafo e aofia ai le ASTM a405 p24 (1% CrMoV, ISA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Siamani), ma isi.
I le taimi nei,12Cr1MoV Paipa Uamea Su'esu'ee fa'aaogaina lautele i le Superheater, ulutala ma le ausa ausa autu o le maualuga o le mamafa, ultra-high pressure ma subcritical power station boilers i le fale ma fafo.O lenei uamea ua avea ma se tasi o mea autu o le afi eletise ma le boiler i le pisinisi eletise a Saina.
I le taimi nei,12Cr1MoV Fa'apa'u Uamea Su'esu'ee masani ona faʻaaogaina i vaega nei:
(1) Faʻaaogaina tele mo paipa faʻafefete, paipa ea, paipa ausa autu, paipa faʻavevela ma isi vaega o mea faʻapipiʻi, aemaise lava i le maualuga o le mamafa ma le ultra-high-pressure boiler, 12Cr1MoVG e faʻaaogaina le uʻamea vevela.
(2) Fa'aaogaina mo le 'au autu,] impeller, rotor, fa'amau (bolt and nut), cylinder, nozzle chamber, lubricating valve, diaphragm and some blade material of steam turbine.
(3) Faʻaaogaina e faʻaitiitia ai le vevela galue o le rotor ma le lau i totonu o le afi afi vevela e tusa ma le 550 ℃, ina ia faʻalauteleina ai le faʻaogaina o le uʻamea vevela vevela i le afi afi.
(4) E mafai ona faʻaaogaina e gaosia ai le rotor turbine gas, impeller, faʻamau ma isi vaega ma le vevela galue i lalo ole 570 ℃.
(5) Faʻaaogaina mo le gaosiga o paipa ogaumu, faʻafefe vevela ma isi paipa faʻavevela i luga ole vailaʻau ma mea faʻaogaina.
