17-4PH Mapepala a Zinthu Zofunika
Zokwanira
Zida zosapanga dzimbiri 17-4 PH zimadziwika ndi mphamvu zokolola zambiri, kukana kwa dzimbiri komanso kukana kwambiri. 17-4 PH ndi imodzi mwazitsulo zofunika kwambiri zomwe zingathe kuumitsidwa. Ndizofanana ndi zida 1.4548 ndi 1.4542.
Kugwiritsiridwa ntchito kwa kutentha kwapakati ndi kotheka ndi Condition H1150 ndi H1025. Mphamvu yamphamvu yowoneka bwino imaperekedwanso pakutentha kocheperako.
Chifukwa cha luso lamakina komanso kukana kwa dzimbiri, zinthuzo ndizoyenera kugwiritsidwa ntchito m'malo am'madzi, koma zimatha kuwonongeka ndi ming'alu m'madzi akunyanja.
17-4PH imadziwika kuti AISI 630.
Zinthu 17-4PH zimagwiritsidwa ntchito pamakampani opanga mankhwala, mafakitale amitengo, gawo lakunyanja, pakumanga zombo, muumisiri wamakina, m'makampani amafuta, m'makampani a mapepala, m'masewera amasewera. Makampani opumula komanso ngati mtundu wosungunukanso (ESU) mumlengalenga ndi Azamlengalenga.
Ngati zida zamakina ndi kukana kwa dzimbiri kwa zitsulo za martensitic sizikwanira, 17-4PH ingagwiritsidwe ntchito.

Ubwino
Chinthu chimodzi chapadera cha zinthu 17-4 PH ndi kuyenerera kwa kutentha kochepa komanso kupezeka kwa pafupifupi. 315 ° C.
Kupanga:Kukonzekera kwa zinthuzo kumachitika pa kutentha kwa 1180 ° C mpaka 950 ° C. Kuonetsetsa kuti tirigu amayenga, kuziziritsa kutentha kumapangidwa ndi mpweya.
Kuwotcherera:Zinthu 17-4 PH zisanawotchedwe, kuganiziridwa kuyenera kuganiziridwa za momwe zinthu ziliri. Mu mawonekedwe okhazikika, mkuwa umapezeka muzinthu. Izi zimathandizira kuti pasakhale kusweka kotentha.
Kuti athe kuchita kuwotcherera momwe akadakwanitsira kuwotcherera zinthu zofunika. Ma undercuts kapena kuwotcherera zolakwika kungayambitse kupanga notch. Zimenezo ziyenera kupeŵedwa. Kupewa mapangidwe maganizo ming'alu, zakuthupi ayenera kachiwiri kuyankha annealing ndi ukalamba wotsatira mkati mwa nthawi yochepa kwambiri pambuyo kuwotcherera.
Ngati palibe chithandizo cham'mbuyo cha kutentha chimachitika, ukadaulo wamakina mumsoko wowotcherera komanso malo okhudzidwa ndi kutentha kuzinthu zoyambira zitha kukhala zosiyana kwambiri.
Kulimbana ndi corrosion:pamene zida zamakina ndi kukana kwa dzimbiri kwa zitsulo za martensitic sizikwanira, 17-4 PH ndiyoyenera kugwiritsidwa ntchito m'malo am'madzi. Ili ndi kuphatikiza kwazinthu zabwino zamakina komanso kukana dzimbiri.
M'madzi a m'nyanja ayima, 17-4 PH amatha kuwononga dzimbiri. Izi zimafuna chitetezo chowonjezera.
Makina:17-4 PH imatha kupangidwa mowumitsidwa komanso yolumikizidwa ndi yankho. Malingana ndi kuuma, machinability amasiyanasiyana, izi zidzadalira chikhalidwe.
Kutentha mankhwala
Pakati pa 1020 ° C ndi 1050 ° C zinthu 17-4 PH ndi yankho-annealed. Izi zimatsatiridwa ndi kuzizira kofulumira - madzi, mafuta kapena mpweya. Izi zimadalira pa mtanda wa zinthu.
Kuonetsetsa kutembenuka kwathunthu kuchokera ku austenite kupita ku martensite, zinthuzo ziyenera kukhala ndi mphamvu yoziziritsa mu firiji.

Ubwino wa macheka odulidwa
Kukonzekera ndi macheka ndi makina opangira zinthu, zomwe zimapangitsa kuti pakhale kutsika kosayembekezereka komanso kuwonjezeka kwa kuuma kwa mapangidwe omwe alipo, monga kudula kwamafuta.
Choncho, workpiece machined ali ndi dongosolo homogeneous ngakhale m'mphepete, amene sasintha kupitiriza zinthu.
Izi zimalola kutha msanga kwa workpiece ndi mphero kapena kubowola. Choncho sikoyenera kuti anneal zinthu kapena kupanga opareshoni yofananira kale.
