Thaum engineers qhia 410 stainless hlau rau lub zog siab, cov khoom siv kho cua sov-xws li hydraulic valve lub cev, twj tso kua mis, lossis winch shafts-lawv tsis yog xaiv cov khoom siv xwb. Lawv tau cog lus rau tus neeg tsim khoom lag luam uas nkag siab tias yuav ua li cas 410 tus qauv martensitic coj tus cwj pwm hauv kev ntxhov siab, nws qhov kev tiv thaiv corrosion tsis txaus xav tau kev tswj xyuas qhov tseeb, thiab vim li cas batch-rau-batch hardness sib xws tseem ceeb tshaj li tus lej tensile ib leeg.
Qhov ntawd yog qhov kev paub cais cov neeg xa khoom los ntawm cov chaw tsim khoom. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau machined tshaj 12,000 410 stainless hlau qhov chaw rau North American oilfield twj tso kua mis txij li thaum 2021-txhua qhov yuav tsum tau Rockwell C42-48 hardness tom qab quenching thiab tempering, ± 0.015 hli geometric kam rau ua ntawm sealing ntsej muag, thiab tag nrho traceability rau ASTM Acert. Peb tau pom cov neeg siv khoom tsis lees paub qhov chaw vim tias micro-cracking nyob ze ntawm cov ntse ntse tom qab kev kho cua sov - thiab tau kawm los hloov kho cov cuab yeej siv thiab ua ntej cua sov mus raws li. Peb kuj tau pom cov neeg yuav khoom tsis pom zoo tias 410 cov ntsiab lus qis nickel ua rau nws nkag siab rau kev tawm tsam intergranular nyob rau hauv ib puag ncig chloride-nplua nuj tshwj tsis yog passivated raug. Cov no tsis yog cov ntaub ntawv hauv qab no. Lawv yog cov lus qhia hauv teb ua rau txhua tus 410 stainless hlau Hoobkas txheej txheem peb khiav.
Precision tsis yog xaiv tau - nws yog tsim rau hauv cov alloy tus cwj pwm
410 stainless hlau muab lub zog los ntawm kev hloov pauv martensitic-tsis yog chromium oxide films. Qhov ntawd txhais tau tias nws qhov kev ua tau zoo nyob rau ntawm peb qhov sib txuas ua ke sib txawv: tshuaj lom neeg muaj pes tsawg leeg (tshwj xeeb tshaj yog cov pa roj carbon thiab chromium tshuav), thermal keeb kwm, thiab kev ua tiav txhua yam. Ib daim ntawv pov thawj zeb txheem tsis tau lees tias muaj kev sib haum xeeb. Peb muab 410 daim ntawv pov thawj rau AMS 5504 thiab txheeb xyuas txhua qhov cua sov nrog OES spectroscopy ua ntej machining. Yog tias carbon drifts saum toj no 0.15%, peb kho tus nqi quench. Yog tias chromium poob qis dua 11.5%, peb chij lub batch - txawm tias nws ua tau raws li ASTM yam tsawg kawg nkaus - vim tias lub ntiaj teb tiag tiag hnav lub neej poob qis.
Peb muab kev kho cua sov ncaj qha rau hauv peb cov haujlwm CNC. Cov khoom mus los ntawm cov chaw tig mus rau lub tshuab nqus tsev nyob hauv qab 90 feeb - tsis muaj qhov cuam tshuam rau qhov chaw. quenching siv cov pa roj nitrogen ntawm kev tswj kev tshaj tawm, tsis yog roj lossis dej, tshem tawm cov kev pheej hmoo cuam tshuam ntawm cov vaj tsev nyias nyias. Tempering tshwm sim hauv 4 teev tom qab quenching, tsis yog hnub tom qab. Vim li cas? Vim hais tias khaws cia austenite converts unpredictably dhau lub qhov rais, pov tawm zaum kawg hardness thiab seem stability. Qib no ntawm kev qhuab qhia metallurgical tsis tuaj yeem sib tham tau thaum koj cov khoom ntim ntawm 3,000 psi lossis tig qis dua 15-tuj winch loads.
Vertical integration daws qhov outsourcing so
Qee tus neeg muab khoom tawm ntawm qhov chaw casting, machining, thiab kev kho cua sov kom cais cov neeg muag khoom. Uas tsim qhov muag tsis pom kev: lub hauv paus tsis paub koj GD&T callouts; lub tshav kub-kho tsis tuaj yeem pom koj qhov chaw ua tiav; tus finisher tau txais qhov chaw nrog cov nplais tsis sib xws lossis decarb txheej. Peb muaj tag nrho peb theem-hauv ib qho ISO 9001-certified chaw hauv Qingdao.
- Casting: Sand-cam khwb cia 410 vaj tse nrog kev taw qhia kev ruaj ntseg tswj-txo qis porosity nyob rau hauv qhov chaw tseem ceeb load los ntawm 62% piv rau cov pa pwm
- Tshuab dhos: 5-axis CNC chaw zov me nyuam nrog rau hauv-txheej txheem probing raug rau thermal loj hlob thaum lub sij hawm ntev txiav ntawm 120-mm-inch piston pas nrig bores
- Ua tiav: Electropolished nto ua tiav Ra ≤ 0.4 µm ntawm qhov chaw sib khi-tsim nrog profileometers, tsis pom kev kwv yees
Qhov no tsis yog hais txog kev yooj yim. Nws yog hais txog kev tiv thaiv tsis ua hauj lwm hom tsis muaj ib tus neeg muag khoom muaj: ib qho kev cuam tshuam los ntawm cov khoom siv ua haujlwm, kev kho cua sov ua kom tsis zoo raws li qhov yuam kev, lossis cov zaj duab xis passivation stripped thaum deburring. Thaum koj xaj los ntawm qhov tseeb 410 stainless hlau Hoobkas, koj tau txais ib pab neeg lav ris rau tag nrho cov saw-los ntawm cov hlau molten mus rau kev ua haujlwm validation.
Kev siv lub ntiaj teb tiag tiag yeej cov ntawv specs txhua lub sijhawm
Peb sim 410 qhov chaw zoo li cov neeg siv kawg ua - tsis yog rau cov qauv ASTM nkaus xwb, tab sis rau daim ntawv thov kev ntxhov siab. Txhua lub tsev nyob hauv siab tau kuaj xyuas cov pov thawj hydrostatic ntawm 1.5 × rated siab, nrog rau kev tshuaj xyuas dye-penetrant ntawm tag nrho cov weld-kho thaj chaw. Txhua lub winch center ncej cov menyuam khiav 72-teev nrawm hnav lub voj voog tiv thaiv cov tawv tawv 42CrMo4 counterfaces - ntsuas qhov poob, qhov hloov ntawm qhov roughness, thiab micro-hardness gradient qhov tob. Peb teev cov txiaj ntsig ntawm ntau tus lej. Koj tau txais cov ntaub ntawv - tsis yog "pass/fail" stamp xwb.
Cov neeg siv khoom feem ntau nug: "Koj puas tuaj yeem tuav ± 0.005 hli ntawm 300-mm-ntev 410 ncej?" Yog lawm-tab sis tsuas yog peb tshuab nws hauv ob qhov kev teeb tsa: ntxhib-tig ntawm lub tshuab dhos nruj, tom qab ntawd ua tiav-sib tsoo tom qab kev ntxhov siab ntawm 650 ° C. Peb yuav qhia rau koj ua ntej. Peb yuav tsis hais qhov kam rau peb tsis tuaj yeem tuav hla 500 units. Thiab yog tias koj daim duab hu rau 0.2-mm radius qhov twg 410's notch rhiab heev xav tau 0.5 hli-peb yuav qhia koj daim ntawv qhia txog kev puas tsuaj thiab qhia txog kev hloov ua ntej txiav hlau.
Kev ntseeg siab hauv 410 stainless hlau pib ntev ua ntej thawj nti ya. Nws pib nrog kev paub tias cov alloy teb li cas - tsis yog nws yuav tsum teb li cas. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua tus. 410 stainless hlau Hoobkas txiav txim raws li kev sib koom tes metallurgical. Peb muab precision qhov chaw. Tab sis qhov tseem ceeb tshaj, peb xa cov kev kwv yees-seem, tshuab, thiab xa khoom. Vim tias lub luag haujlwm tseem ceeb hauv lub luag haujlwm tsis ua tiav los ntawm cov khoom tsis zoo. Lawv ua tsis tau los ntawm kev hloov pauv tsis tau. Thiab cov kev hloov pauv no nyob hauv cov ntsiab lus peb tswj.
