15-7PH ni imvura igwa igice cya austenitike ikomera ibyuma bitagira umwanda n'imbaraga nyinshi, ubukana bwinshi hamwe no kurwanya ruswa.Muri rusange kurwanya ruswa mu bushyuhe bwavuwe TH 1050 na RH 950 ni bibi cyane kuruta ibyuma bisanzwe bitangirika ibyuma bya chromium bishingiye kuri 400, ariko ntabwo ari byiza nkibya chromium-nikel bishingiye kuri 304 ibyuma bitagira umwanda.
PH15-7Mo (andika 632) igipimo cyigihugu 0Cr15Ni7Mo2Al, Ubuyapani SUS632, nicyuma cyakozwe mugusimbuza 2% ya chromium muri 0Cr17Ni7Al ibyuma na molybdenum 2%.Ibikoresho byibanze bisa na 0Cr17Ni7Icyuma cyose, ariko imikorere rusange iraruta.Muri leta ya austenite, irashobora kwihanganira uburyo butandukanye bwo gukonjesha no gusudira, hanyuma imbaraga zisumba izindi zishobora kuboneka nyuma yo kuvura ubushyuhe;ifite ubushyuhe bwo hejuru cyane munsi ya 550 ℃.Ikoreshwa mugukora ibice byindege byoroheje byubatswe nindege, ibikoresho bitandukanye, imiyoboro, amasoko, membrane ya membrane, shitingi yubwato, disiki ya compressor, ibice bya reaktor, nibikoresho bitandukanye bya shimi nibindi bice byubatswe.

Sisitemu yo kuvura ubushyuhe 15-7PH: Leta, Leta ya TH1050, Leta ya RH950, Leta ya CH900 Uburyo butatu bwo kuvura ubushyuhe

Leta A: Nyuma yo kuvura igisubizo kuri 1050 ° C, gukonjesha amazi cyangwa gukonjesha ikirere.Imiterere ya metallografiya irangwa na austenite.

TH1050 vuga: Nyuma yo kuvura igisubizo kuri 1050 ° C, komeza kuri 760 ° C ± 15 ° C kuri 90min, gukonjesha ikirere, gukonja kugeza kuri 15 ° C cyangwa ubushyuhe bwicyumba muri 1h, komeza 30min, hanyuma ushushe kuri 565 ° C ± 10 ° C, komeza 90min mu kirere, bizwi kandi ko gusaza 565 ° C.Imiterere ya metallografiya irangwa nimvura ikomera martensite.

RH950 ivuga: Nyuma yo kuvura igisubizo kuri 1050 ° C, komeza kuri 955 ° C ± 15 ° C muminota 10, ubukonje-mwuka kugeza ubushyuhe bwicyumba, ubukonje kugeza kuri -73 ° C ± 6 ° C mumasaha 24, komeza amasaha 8, hanyuma ushushe kuri 510 ° C ± 6 ° C, komeza iminota 60 mugukonjesha ikirere, Bizwi kandi nka 510 ℃ gusaza.Imiterere ya metallografiya irangwa nimvura ikomera martensite.

CH900 ivuga: Nyuma yo kuvura igisubizo kuri 1050 ° C, gukonjesha gukonje hamwe no guhindura 60%, gushyushya 490 ° C kuri 60min, gukonjesha ikirere kugeza ubushyuhe bwicyumba.Imiterere ya metallografiya irangwa nimvura ikomera martensite.
