17-4PH Material Data Sheet
Scopes
Iyo isina tsvina 17-4 PH inoratidzwa nekusimba kwegoho rakawanda, kunaka kwekusagadzikana kwecorrosion uye kushomeka kwepamusoro. 17-4 PH imwe yesimbi yakakosha inogona kuomeswa. Izvo zvakafanana nekuongorora zvinhu 1.4548 uye 1.4542.
Iko kushandiswa kwepasi-tembiricha renji kunogoneka neCondition H1150 uye H1025. Yakanakisa notched simba rekuita rinopihwawo paminus tembiricha.
Nekuda kwezvakanaka zvemakina zvivakwa uye kusadzivirirwa nekuora, zvinhu zvacho zvakakodzerwa kushandiswa munzvimbo dzemugungwa, asi zvinokonzeresa kukoromoka mumvura yakamira yegungwa.
17-4PH inonyanya kuzivikanwa seAISI 630.
Iyo zvinhu 17-4PH inoshandiswa muindasitiri yemakemikari, indasitiri yehuni, iyo offshore chikamu, mukuvaka ngarava, mune mechaniki engineering, muindasitiri yemafuta, muindasitiri yemapepa, muindasitiri yemitambo. Indasitiri yekuvaraidza uye seyakanyungudutswazve vhezheni (ESU) mumhepo uye Aerospace.
Kana ma mechanical properties uye corrosion resistance yemartensitic steels isina kukwana, 17-4PH inogona kushandiswa.

Advantage
Imwe yakakosha pfuma yezvinhu 17-4 PH ndiko kukodzera kwekudziya kwakadzika uye kushanda kusvika approx. 315°C.
Kugadzira:Kugadzirwa kwezvinhu kunoitika muhutano hwe1180 ° C kusvika 950 ° C. Kuve nechokwadi chekunatswa kwezviyo, kutonhora kwekamuri kunoitwa nemhepo.
Welding:Pamberi pezvinyorwa 17-4 PH zvinogona kusungirirwa, kufunga kunofanirwa kupihwa kune mamiriro eiyo base zvinhu. Muchimiro chakagadzikana, mhangura iripo mune zvinyorwa. Izvi zvinokurudzira kusaputika kunopisa.
Kuti ukwanise kuita welding optimum welding mamiriro anodiwa. Undercuts kana welding defects inogona kutungamira mukuumbwa kwenotch. Izvozvo zvinofanira kudziviswa. Kudzivirira kuumbwa kwekushushikana kutsemuka, zvinhu zvacho zvinofanirwa kuve pasi pekugadzirisa annealing nekuchembera kunotevera mukati menguva pfupi mushure mewelding.
Kana pasina mushure-kupisa kurapwa kunoitika, iyo mechanika-tekinoroji kukosha mune weld seam uye iyo inopisa-yakakanganiswa nzvimbo kune base zvinhu zvinogona kusiyana zvakanyanya.
Corrosion resistance:apo mechanical properties uye corrosion resistance yemartensitic steels isingakwani, 17-4 PH yakakodzera kushandiswa munzvimbo dzegungwa. Iine musanganiswa weakanaka kwazvo ma mechanical properties uye corrosion resistance.
Mumvura yegungwa yakamira, 17-4 PH inobatwa negora. Izvi zvinoda kumwe kudzivirirwa.
Machining:17-4 PH inogona kugadzirwa mune yakaomeswa uye mhinduro-yakagadziriswa mamiriro. Zvichienderana nekuoma, machinability inosiyana, izvi zvinoenderana nemamiriro ezvinhu.
Kurapa kwekupisa
Pakati pe1020 ° C uye 1050 ° C zvinhu 17-4 PH inogadziriswa-yakagadziriswa. Izvi zvinoteverwa nekukurumidza kutonhora - mvura, mafuta kana mhepo. Izvi zvinoenderana nekuyambuka-chikamu chezvinyorwa.
Kuve nechokwadi chekutendeuka kwakazara kubva kune austenite kuenda kune martensite, zvinhu zvacho zvinofanirwa kuve nekugona kutonhora pasi mukamuri tembiricha.

Zvakanakira zvemasaha
Kugadziriswa nesaha ndeye mechanical processing yezvinhu, izvo zvinoguma nekuderera kwakanyanya kusingatarisirwi uye kuwedzera kuoma kwechimiro chiripo, sekucheka kwekushisa.
Saka, iyo machined workpiece ine homogeneous chimiro kunyange pamucheto, iyo isingashanduki mukuenderera mberi kwezvinhu.
Mamiriro ezvinhu aya anobvumira kukurumidza kupera kweworkpiece nekugaya kana kuchera. Saka hazvidikanwi kuti anneal zvinhu kana kuita zvakafanana oparesheni kare.
