Thaum engineers qhia 316 los yog 316L stainless hlau rau cov khoom tseem ceeb-siab li qub nyob rau hauv offshore hydraulic systems, lub tog raj kheej vaj tse rau high-pressure piston twj, los yog winch center ncej chais rau engineering tsheb-lawv tsis yog tsuas yog xaiv cov khoom. Lawv tab tom xaiv qhov kev lav phib xaub rau kev ua haujlwm: tsis kam mus rau chloride-induced pitting, kev ruaj ntseg ntawm qhov kub siab, thiab kev ncaj ncees mus sij hawm ntev hauv cov tshuaj lom neeg ib puag ncig. Tab sis qhov kev lees paub tsuas yog tuav yog tias lub Hoobkas xa cov khoom xa tuaj rau peb yam: metallurgical sib xws, kev ncaj ncees nyob rau hauv nruj GD&T tswj, thiab xoom kam rau ua rau cov txheej txheem drift hla batches.
Tias yog vim li cas muab los ntawm qhov tseeb 316 316L stainless hlau Hoobkas Qhov teeb meem - tsis yog cov khoom siv hlau dav dav, tsis yog lub tuam txhab lag luam npog ua cov chaw tsim khoom, tab sis qhov chaw uas txhua qhov cua sov ntawm 316L tuaj yeem taug qab tau cov ntawv pov thawj zeb xeem, qhov twg CNC machining tsis tau kho tshwj xeeb rau austenitic stainless ntws cov yam ntxwv, thiab qhov twg casting porosity raug ntes ua ntej kev kho cua sov kawg - tsis yog tom qab.
Peb tau pom ntau txoj haujlwm qeeb vim tias "tus neeg muag khoom tsis muaj steel" lees txais cov duab kos yam tsis muaj chij tias lub hauv paus nyias 316L lub twj tso kua mis yuav ua rau muaj kev ntxhov siab thaum lub sij hawm txo kev ntxhov siab tshwj tsis yog machined nyob rau hauv ib theem nrog tswj clamping quab yuam. Peb tau sim AMS 5387 cobalt alloy nozzles sab-los-sab nrog 316L sib npaug hauv kev simulated seawater txhaj cycles-thiab saib cov stainless tuav qhov twg pheej yig dua lwm yam ua tsis tau tejyam ntawm 2,800 teev. Qhov ntawd tsis yog kev paub theoretical. Nws tau tsim los rau hauv peb cov cuab yeej, peb cov txheej txheem tshuaj xyuas, thiab seb peb ntsuas txhua qhov CMM sojntsuam ua ntej ntsuas 316L valve lub rooj zaum saum npoo.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., precision tsis yog txheej saum toj kawg nkaus ntawm kev tsim khoom - nws tau tsim kho rau hauv nws. Peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao tuav ob qho kev nqis peev-cam khwb cia thiab xuab zeb-cam khwb cia 316/316L stainless hlau qhov chaw, tom qab ntawd ua tiav lawv nrog ntau-axis CNC machining uas tuav ± 0.01 hli kam rau ua rau cov yam ntxwv zoo li sealing nto thiab bolt-qhov qauv. Peb tsis outsource kev kho cua sov. Peb tsis lees txais daim ntawv pov thawj uas tsis tau lees paub. Txhua yam khoom siv raw tau dhau los ntawm kev tshuaj xyuas spectrographic thaum tuaj txog - thiab tag nrho cov khoom siv taug qab tau muab tso rau hauv peb qhov system ERP mus rau qhov cub hluav taws xob thiab tus nqi cua txias.
- Kev tswj cov khoom pib ua ntej txiav: Peb muab 316L los ntawm cov mills tau ntawv pov thawj rau ASTM A240 / A484, nrog Mo cov ntsiab lus tuav ntawm 2.0-3.0% thiab carbon ≤0.03% - txheeb xyuas ib qho cua sov, tsis yog khoom xa tuaj.
- Machining tsis txhob ua hauj lwm hardening: Peb siv low-RPM, high-feed strategies nrog PVD-coated carbide cov cuab yeej tsim los rau austenitic stainless, txo tshav kub buildup thiab preserving corrosion kuj ntawm txheej txheej.
- Nto kev ncaj ncees yog tsis-negotiable: Rau cov twj tso kua mis raug rau brine, peb siv passivation rau ASTM A967 (Txoj Kev B) thiab txheeb xyuas Cr / Fe piv nrog XRF - tsis muaj kev kuaj pom nkaus xwb.
- Dimensional validation tshwm sim peb zaug: pre-machining (cov ntaub ntawv pov thawj), nruab nrab txheej txheem (cov ntaub ntawv tseem ceeb), thiab tom qab ua tiav (tag nrho CMM scan tawm tsam CAD qauv).
Ib txhia yuav sib cav hais tias ib qho ISO-certified foundry tuaj yeem tsim 316L castings. Tab sis casting 316L tsis zoo li casting grey hlau. Nws cov nickel thiab molybdenum siab cov ntsiab lus ua rau kub tearing txaus ntshai. Nws tsis tshua muaj thermal conductivity xav tau pwm preheat tswj. Thiab nws txoj kev nyiam ua sigma theem thaum lub caij txias qeeb txhais tau hais tias cov sijhawm kho cua sov yuav tsum raug lees paub - tsis xav. Peb tau tshem tawm ob lub qauv cua sov vim tias cov cua txias poob sab nraum lub qhov rais 5 ° C / min xav tau kom tsis txhob muaj kev ntxhov siab. Qhov ntawd yog tus nqi hla kev qhuab qhia metallurgical.
Peb lub zog nyob hauv kev sib xyaw ua ke ntsug: casting, machining, kev kho cua sov, thiab kev ua tiav tshwm sim nyob rau hauv ib lub ru tsev, nrog rau cov qauv ntsuas ntsuas thiab cov lus qhia lub sijhawm tiag tiag ntawm cov chaw haujlwm. Thaum tus neeg siv khoom xa daim duab kos rau qhov tsis yog tus qauv 316L siab valve lub cev nrog asymmetric txias raws, peb pab neeg tsis yog hais nqe lus thiab lub sijhawm ua. Peb khiav solidification simulation, qhia me me geometry tweaks kom txo tau cov kab noj hniav shrinkage, thiab tawm tswv yim ib tug machining ib theem zuj zus uas txo re-clamping-txiav lub voj voog sij hawm los ntawm 22% yam tsis muaj faus flatness.
Cov neeg siv khoom thoob ntiaj teb - los ntawm hydraulic OEMs hauv lub teb chaws Yelemees mus rau cov chaw muab kev pabcuam roj av hauv Texas - cia siab rau peb vim tias kev ntseeg siab tsis yog kev lag luam thov ntawm no. Nws ntsuas tau: 99.4% kev xa khoom raws sijhawm nyob rau 18 lub hlis dhau los, xoom teb tsis ua haujlwm khi rau cov khoom tsis raug, thiab kev tshuaj xyuas tag nrho rau ASME BPVC Tshooj II lossis PED 2014/68 / EU cov ntaub ntawv ua raws. Peb xa 316 thiab 316L stainless hlau Cheebtsam rau North America, Europe, thiab Southeast Asia - tsis yog cov khoom muag, tab sis raws li cov ntaub ntawv, traceable, functionally validated qhov chaw.
Yog koj xav tau ib 316 316L stainless hlau Hoobkas uas kho koj cov khoom xws li lub hom phiaj tseem ceeb kho vajtse - tsis yog cov khoom lag luam SKU - koj xav tau cov neeg koom tes uas tau siv ntau pua ntawm 316L lub tog raj kheej rau cov twj tso kua mis triplex av nkos, uas nkag siab tias vim li cas lub kaum sab xis ntawm 0.5 ° teeb meem ntau dua li qhov roughness ntawm seawater valve lub rooj zaum, thiab leej twg khaws cov ntaub ntawv raw cov ntaub ntawv nrog rau txhua qhov kev xa khoom. Qhov ntawd tsis yog kev coj ua. Nws yog peb txoj haujlwm niaj hnub.
Saib tom ntej: peb tab tom nthuav peb lub peev xwm hauv hybrid casting-machining txheej txheem rau loj-inch 316L cov rooj sib txoos thiab sib sib zog nqus R & D ntawm qis-kub tshuaj annealing rau kev txhim kho intergranular corrosion kuj. Vim hais tias nyob rau hauv high-stakes industrial daim ntaub ntawv, txoj cai stainless hlau feem tsis yog ua xwb. Nws tau khwv tau -batch los ntawm batch, cua sov los ntawm tshav kub, ntsuas los ntawm kev ntsuas.
