Kub txoj kev
Qhov pom zoo ua haujlwm kub yog 1700-2200℃F (927-1204 degree). Yuav kom ua tiav qhov zoo tshaj plaws corrosion kuj, annealing yuav tsum tau ua nyob rau ntawm qhov kub ntawm tsis tsawg tshaj li 1900℃F (1038 degree), ua raws li cov dej quenching los yog lwm yam ceev txias txoj kev tom qab kub ua hauj lwm.
Vuam
Vuam Qib 316 yuav tsum tau muab cov hlau sib txuam, feem ntau AWS ER316L lossis E316L-16, kom tswj tau cov ntsiab lus molybdenum hauv cov weld nugget thiab tiv thaiv kev sib tsoo hauv cheeb tsam. Ua kom tiav cov hauv paus tiv thaiv thaum lub sij hawm TIG vuam kom tsis txhob muaj suab thaj oxidation ntawm sab nraub qaum, uas ua raws li qhov chaw pib rau pitting.

"Yuav ua li cas tiv thaiv 316 stainless hlau phaj los ntawm warping thaum vuam?" / "Vim li cas 316 thiaj li nyuaj rau tshuab tsis khoov?"
Vim tias cov thermal conductivity tsawg thiab siab thermal expansion coefficient ntawm austenitic stainless hlau, cov khoom no muaj kev cuam tshuam rau thermal deformation thaum vuam thiab tshem tawm cov khaub thuas{0}} dov daim tawv nqaij. Txhawm rau kom ua tiav qhov kawg, nws raug nquahu kom siv cov plooj vuam thiab nruj fixturing thaum lub sij hawm vuam txheej txheem, thiab yuav tau txais ib tug machining lub tswv yim uas muaj xws li symmetrical tshem tawm cov khoom ua ke nrog intermediate kev nyuaj siab nyem.

Tiag -Kev Kawm Txuj Ci Ntiaj Teb
Puas yog 316 stainless hlau xeb hauv dej ntsev?
Yuav ua li cas kom tsis txhob 316 phaj los ntawm tshuaj yej staining nyob rau hauv ntug hiav txwv dej?
Qib 316 yog "corrosion-resistant" (stainless) es tsis yog " xeb kiag li- pov thawj." Nyob rau hauv ib puag ncig marine los yog cov ntug dej hiav txwv zones uas muaj cov tshuaj chloride siab, cov khoom muaj kev cuam tshuam rau hauv zos pitting lossis "tshuaj yej staining" yog tias nws tsis muaj dej tsis tu ncua, polishing nto, los yog passivation - lossis yog tias nws dhau los ua paug nrog cov hlau dawb los ntawm cov cuab yeej carbon steel thaum tsim thiab teeb tsa. Tsuas yog los ntawm kev xaiv lub siab - zoo nto tiav (xws li # 4 tiav lossis daim iav tiav) thiab ua kom cov kev ua haujlwm tsis zoo tuaj yeem ua tiav qhov corrosion tag nrho -kuj muaj peev xwm ntawm Qib 316 tau paub.
Dab tsi yog qhov txawv ntawm 304 thiab 316 stainless hlau phaj hauv marine ib puag ncig?
316 stainless hlau (UNS S31600 / EN 1.4401) suav nrog kwv yees li 2-3% molybdenum (Mo) rau hauv nws cov tshuaj muaj pes tsawg leeg, imparting superior tiv taus pitting thiab crevice corrosion. Hauv cov huab cua hauv hiav txwv, tshuaj tsuag ntsev, thiab cov tshuaj chloride- muaj ib puag ncig, 316 muaj kev tiv thaiv corrosion- kev ua neej nyob deb tshaj li ntawm 304, tiv thaiv kom tsis txhob muaj xeb liab ntxov ntxov thiab tsis ua hauj lwm hauv cheeb tsam.
Seawater Heat Exchanger Failure Analysis Case
Ib tug ntug dej hiav txwv desalination chaw Ameslikas ntsia 304 stainless hlau daim hlau. Tom qab kwv yees li 18 lub hlis, qhov chaw pitting corrosion tshwm nyob ze thaj chaw weld. Cov phaj tau hloov nrog 316 stainless hlau. Tab sis nyob rau hauv ib puag ncig uas muaj kub ua hauj lwm siab tshaj 60℃thiab siab chlorine concentrations, pitting tseem tuaj yeem tshwm sim nyob rau lub sij hawm, yuav tsum tau hloov kho kev ntsuam xyuas rau duplex 2205/2507 qib los yog super austenitic alloys.
Engineer's Notes:
Ntau tus neeg siv feem ntau xav tsis thoob txog thaum twg yuav "kho dua tshiab" lawv cov khoom xaiv los ntawmQib 304mus rau Qib 316. Lawv raug ntes ntawm ob qhov kev txhawj xeeb: kev ntshai ntawm kev them tus nqi tsis tsim nyog ntawm 20% mus rau 30%, thiab kev ntshai ntawm qhov tshwm sim "cov nqi zais" uas tshwm sim los ntawm cov khoom tsis ua haujlwm ntxov ntxov -xws li corrosion los yog xeb- nyob rau hauv marine lossis chemical processing ib puag ncig.
Qib 316 stainless hlau yog cov khoom tshwj xeeb rau kev siv hauv marine chaw thiab kev ua haujlwm corrosive. Rau cov phiaj xwm npaj rau kev pabcuam ntev - lub sijhawm, cov lus cog tseg ntawm kev ua haujlwm txuas ntxiv ua haujlwm ua haujlwm tau zoo heev rau cov neeg siv khoom.
Tsis tas li ntawd, yog tias yuav tsum tau vuam, xaiv rau Qib316L stainless hlauzoo tshem tawm txoj kev pheej hmoo ntawm carbide nag lossis daus. Qhov kev ntsuas no ua haujlwm los tiv thaiv kev nyab xeeb ntev ntev -Lub Sijhawm Rov Qab Los Ntawm Kev Lag Luam (ROI) rau koj qhov project.
Yuav ua li cas txheeb xyuas dual{0}} ntawv pov thawj 316/316L stainless hlau daim hlau ntawm daim ntawv pov thawj zeb xeem (MTCs)?
Dual- ntawv pov thawj 316/316L steel phaj ua tau raws li qhov yuav tsum tau muaj zog ntawm Qib 316 thiab cov ntsiab lus qis carbon cov ntsiab lus ntawm Qib 316L (C Tsawg dua lossis sib npaug li 0.030%). Thaum lub sij hawm kev tshuaj xyuas digital ntawm Cov Khoom Siv Xeem Ntawv Pov Thawj (MTC), nws yog qhov tseem ceeb los xyuas kom meej tias cov ntsiab lus carbon ua tau raws li ob qho qauv; qhov no ua kom lub phaj tuaj yeem tiv taus vuam thermal cycles (tsawg carbide nag lossis daus) thaum tuav lub siab -kub txhua yam muaj zog tus yam ntxwv ntawm qib 316.

ASTM A 240 Cov Lus Qhia: specification rau chromium, chromium-nickel, thiab chromium-manganese-nickel stainless hlau phaj, ntawv, thiab sawb.
FAQ:
Q: Tus nqi ntawm 316 stainless hlau phaj nyob rau hauv 2026 yog dab tsi?
A: Tus nqi nruab nrab yog kwv yees li $ 2.8- $ 6.5 ib kg nyob ntawm tuab, tiav, thiab ntau.
Q: Vim li cas 316 stainless hlau kim dua 304?
A: 316 muaj molybdenum, uas txhim kho kev tiv thaiv chloride corrosion piv rau 304, ua pov thawj tus nqi siab dua.
Q: Qhov txawv ntawm 316 thiab 316L yog dab tsi?
A: 316L yog qhov "tsawg carbon" version, uas tiv thaiv carbide nag lossis daus thaum vuam, ua rau nws zoo dua rau hnyav - cov ntaub ntawv siv vuam.
Q: 316 phaj tuaj yeem siv rau kev siv dej hiav txwv?
A: Yog, 316 yog qhov kev xaiv tus qauv rau cov cheeb tsam hauv hiav txwv, txawm tias muaj cov tshuaj chloride heev, peb tuaj yeem hais qhia 2205 Duplex.
Q: Yuav ua li cas koj txheeb xyuas qhov zoo ntawm koj daim hlau stainless?
A: Txhua lub phaj yog nrog los ntawm MTC (Cov Khoom Siv Xeem Certificate) tshawb xyuas cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab tawm tsam ASTM cov qauv.
Q: Koj puas txhawb qhov ntau thiab tsawg thiab laser txiav?
A: Yog, peb muab tag nrho - kev pabcuam txiav thiab profile raws li koj daim duab CAD.
Q: Vim li cas stainless hlau tawg tom qab vuam?
A: Kev tawg tom qab vuam feem ntau tshwm sim los ntawm kub tawg (solidification cracking) tshwm sim los ntawm cov cua kub tsis raug, tsis muaj ferrite tswj nyob rau hauv lub vuam hlau, los yog paug los ntawm leej faj thiab phosphorus impurities thaum fabrication.
Q: Puas yog 316 stainless hlau phaj sib nqus?
A: Nyob rau hauv nws tag nrho annealed austenitic mob, 316 yog qhov tseem ceeb tsis yog -magnetic. Txawm li cas los xij, nws tuaj yeem nthuav tawm me ntsis sib nqus permeability tom qab ua haujlwm txias, khoov, lossis vuam vim muaj zog-induced martensite tsim.
Q: Qhov siab tshaj plaws ua haujlwm kub rau Qib 316 yog dab tsi?
A: Qib 316 nthuav tawm cov kev pabcuam zoo sib xws txog 870℃thiab kev pabcuam txuas mus txog 925 degree. Txawm li cas los xij, tsis tu ncua raug nyob rau hauv 425℃-{5}}℃ntau yam yuav tsum tau zam yog tias aqueous corrosion kuj tseem ceeb, vim yog nag lossis daus carbide.
