15-7PH Zvinhu Zvekushandisa
15-7PH is a semi-austenitic precipitation inoomesa simbi isina tsvina ine simba rakawanda, kuomarara kwepamusoro uye kunaka kwekusagadzikana.Kudzivirirwa kwehuori kwese mukupisa kunobatwa TH 1050 uye RH 950 mamiriro akaipisisa kupfuura aya akajairwa masimbi asina tsvina echromium-based 400 akatevedzana, asi asina kunaka seayo echromium-nickel-based 304 masimbi asina tsvina.
PH15-7Mo (mhando 632) yenyika chiyero 0Cr15Ni7Mo2Al, Japan SUS632, isimbi yakagadzirwa nekutsiva 2% yechromium mu0Cr17Ni7Al simbi ine 2% molybdenum.Zvimiro zvayo zvekutanga zvakafanana ne0Cr17Ni7Al simbi, asi kuita kwese kuri nani pane iyo.Mune austenite state, inogona kumira zvakasiyana-siyana kutonhora kuumba uye welding maitiro, uye ipapo simba repamusoro rinogona kuwanikwa mushure mekupisa kupisa;ine yakanakisa tembiricha yesimba iri pasi pe550 ℃.Inoshandiswa mukugadzira avhiyesheni dzakatetepa-namadziro maumbirwo zvikamu, midziyo yakasiyana-siyana, pombi, zvitubu, vharafu membranes, chikepe shafts, compressor discs, reactor zvikamu, uye siyana makemikari midziyo nezvimwe structural zvikamu.
15-7PH Heat Treatment System: A state, TH1050 State, RH950 State, CH900 State Three Heat Treatment Systems
State A: Mushure mekugadzirisa kugadzirisa pa 1050 ° C, kutonhora kwemvura kana kutonhora kwemhepo.Iyo metallographic chimiro inoratidzwa ne austenite.
TH1050 mamiriro: Mushure mekugadzirisa kurapwa pa 1050 ° C, chengetedza pa 760 ° C ± 15 ° C ye 90min, mhepo-inotonhorera, inotonhorera kusvika ku15 ° C kana kupisa kwekamuri mukati me1h, chengetedza 30min, wozopisa kusvika ku565 ° C± 10. °C, chengeta kwe90min mumhepo, inozivikanwawo se565°C kuchembera.Iyo metallographic chimiro inoratidzwa nekunaya kunoomesa martensite.
RH950 mamiriro: Mushure mekugadzirisa kurapwa pa 1050 ° C, chengetedza pa 955 ° C ± 15 ° C kwemaminitsi gumi, mhepo-inotonhorera kusvika kune imwe tembiricha, inotonhorera kusvika -73 ° C± 6 ° C mukati maawa makumi maviri nemana, chengeta kwemaawa masere, ipapo kupisa kusvika 510 ° C ± 6 ° C, chengeta kwemaminitsi makumi matanhatu mumhepo-inotonhorera, Inozivikanwawo se 510 ℃ kuchembera.Iyo metallographic chimiro inoratidzwa nekunaya kunoomesa martensite.
CH900 mamiriro: Mushure mekugadzirisa kurapwa pa 1050 ° C, kutonhora kunotenderera ne 60% deformation, kupisa kusvika 490 ° C kwe 60min, kutonhora kwemhepo kusvika kune tembiricha yekamuri.Iyo metallographic chimiro inoratidzwa nekunaya kunoomesa martensite.
