Austenitic stainless simbi fekitori mhinduro dzinofanirwa kuunza zvinopfuura kungoteedzera zvinhu - dzinofanirwa kuvimbisa kuramba kwecorrosion iyo inopona basa repasirese: yakakwira chloride kuratidzwa muoffshore hydraulics, thermal cycling mudzimba dzepombi, kana abrasive slurry kusangana muinjiniya mota winch masisitimu. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., takagadzira anopfuura zviuru gumi nezviviri austenitic stainless simbi zvikamu zvekumanikidza mavharuvhu uye piston pombi humburumbira housings kubvira 2019-uye kutadza kwese kuongorora kwakatidzidzisa chinhu chimwe chete: kuramba ngura haina kubikwa mugiredhi. Yakagadzirirwa mukutonga kwemaitiro.
Corrosion Resistance Inotanga Usati Wagadzira-Kwete Mushure
Vazhinji vatengi vanofungidzira ASTM A351 CF8M kana UNS S31603 otomatiki yakaenzana ne "corrosion-proof." Vakarasika. Takaona kukanda kwakafanana kuchikundikana munzvimbo dzakafanana dzemvura yegungwa-imwe yakapfuura 2,000-awa yemunyu-spray test; imwe yakapinda mukati maawa makumi manomwe nemaviri. Root cause? Kwete kutsauka kwemakemikari-asi kusimba kusingawirirani panguva yekukanda jecha. Local microsegregation yakagadzira nzvimbo dzakapera chromium pamwe nemiganhu yeinterdendritic. Kugadzirisa kwanga kusiri kudzokorora. Yakanga ichigadzirazve gating system, ichiwedzera inonangidzira chill mahwendefa, uye yakabata yemvura tembiricha yesimbi mukati me ± 5 ° C panguva yekudira. Ndiwo mabatiro atinoita nhamba yeferrite pakati pe5–8 FN mukukandira kwese kweCF8M—kunosimbiswa nemagineti probe *pamberi* kurapwa kwekupisa, kwete mushure.
Isu hatibudisi simbi. Zvinyorwa zvedu zvakasvibirira zvinoteedzera kupisa kwega kwega kune mill test mishumo (MTRs) inoratidza chaiyo Cr, Mo, Ni, uye N zvemukati-kwete chete "zvinosangana nezvinodiwa." Nezve maapplication akakosha senge AMS 5387 cobalt alloy pombi zvikamu zvinoshanda padivi peaustenitic housings, tinoona kuenderana kwegalvanic kuburikidza neakavhurika-seketi anogona kuyerwa mune yakateedzera sevhisi maelectrolyte. Kana mutsauko ungangopfuura 50 mV, isu tinogadzirisa pamusoro passivation paramita - kunyangwe iyo base alloy iri "chaiyo."
Iko Kwakawanda Austenitic Stainless Simbi Fekitari Inopokana
Vamwe vatengesi vanopa zvivakwa zve “ISO-certified” pavanenge vachishandisa macaliper anobatwa nemaoko kuti vatarise kekupedzisira majenari e0.005 mm tolerance shaft. Isu hatidaro. Yese austenitic Stainless simbi chikamu chinosiya nzvimbo yedu yeQingdao inoongororwa matatu asingagone kutaurirana:
- Surface kutendeseka verification: White-light interferometry pazviso zvakanamwa, kwete kungokasharara (Ra) kukosha-nekuti nzvimbo yakatsetseka ine pasi pevhu kubvaruka inokoka kukoromoka.
- Passive layer yekusimbisa: Electrochemical impedance spectroscopy (EIS), kwete chete nitric acid dip bvunzo-saka isu tinoyera oxide ukobvu uye kuremara density, kwete kungochinja kweruvara.
- Residual stress mepu: X-ray diffraction panzvimbo 5 dzakakosha pachikamu chimwe nechimwe, kunyanya pedyo nemafiritsi neshinda-sezvo tensile stress pamusoro pe200 MPa inomhanyisa SCC munzvimbo dzechloride.
Imwe yeEuropean hydraulic OEM yakaramba kutumirwa kwedu kwekutanga kweS31603 pombi nheyo-kwete yekukanganisa kwedimensional, asi kune yakasara yekushushikana spikes pedyo nemakomba anokwira. Isu takapindura nemamepu akazara ekushushikana, tichibva tagadziridza iyo clamping fixture uye nekuwedzera kushushikana-yekuzorodza vibration kuchembera pamberi pekupedzisira machining. Delivery yakatsvedza mavhiki maviri. Hupenyu hweCorrosion hwakawedzera kubva kumwedzi 18 kusvika ku47 mumiyedzo yemumunda. Ndiko kutengeserana-off hapana dhairekitori inoratidza.
Kuita Kwechokwadi Kwenyika Inoda Kupedzwa Kwechokwadi-Nyika
Machining mamaki ane basa. Iyo 0.8 µm Ra yekupedzisa inogona kusangana nemadhirowa - asi kana iwo mamaki akaenderana kuyerera kuyerera mumuviri wevharuvhu, anove nzvimbo dzekutangisa ngura. Isu tinotarisisa nzira dzematurusi kuti dzienderane nekurodha masevhisi: circumferential yekutenderera shafts, axial ye static housings, uye blended radii pakuchinja. Kune T800 cobalt-based components welded in austenitic assembled, tinoshandisa electropolishing * after* welding-kwete kare-kubvisa kupisa-kukanganisa zone oxides pasina kuderedza weld toe.
Yedu yakanyanya kukumbirwa kusimudzira? Passivation ne citric acid + sodium nitrate panzvimbo yechinyakare nitric acid. Sei? Nekuti citric acid inobvisa simbi yemahara isina kunyungudutsa chromium-yakakosha kana uchigadzira duplex-austenitic hybrid zvikamu. Isu tinosimbisa mibairo nemhangura sulfate yekuyedza * uye* ferroxyl chiratidzo chemhinduro, tichitarisa zvese kuchena kwepasi uye kungofanana kwefirimu. Vatengi vanoshuma 3.2 × mashoma kutadza kwemunda mukumisikidzwa kwemahombekombe mushure mekuchinja.
Kusarudza Austenitic Stainless Steel Factory Zvinoreva Kusarudza Mushandi Wekuita
Kana chikumbiro chako chinosanganisira cyclic pressure, tembiricha yakakwira, kana kusanganiswa-zvinhu, giredhi rezvinhu rinongova nhanho yekutanga. Nhanho yechipiri ndeyekuona kuti mutengesi anodzora sei kupatsanura, kushushikana, uye mamiriro epamusoro pamabhechi. Nhanho yechitatu inosimbisa kuti QA yavo haimire pakuenderana-inoyera maitiro e electrochemical, microstructural homogeneity, uye kushanda kwenguva refu.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshanda sekuwedzera kwechikwata chako cheinjiniya-kwete mutengesi wezvikamu. Isu tinoongorora zvakare GD&T macallouts ekugadzirwa kwemaitiro pakupokana nekuora. Isu tinocherekedza vangangoita galvanic vakaroorana vasati vatanga kukanda. Isu tinochengeta yakazara zvinhu traceability pasi kusvika kune ladle nhamba uye kupisa-kurapa kutenderera dhizaini. Uye kana corrosion yaonekwa musevhisi, isu hatitumire chinotsiva-tinotumira midzi-chikonzero mushumo ine metallurgical cross-sections uye remediation protocol.
Kuvimbika corrosion kuramba haina kuvimbiswa negiredhi rezita. Inowanikwa mune yekutanga, yakasimbiswa murabhoritari, uye yakasimbiswa mumunda. Ndiyo chiyero chese austenitic stainless simbi fekitori inofanirwa kusangana-asi vashoma vanozviita.
