1.4301 stainless hlau vs. 316L: Kev Ua Si Vuam

Hauv thaj teb ntawm stainless hlau vuam cov ntawv thov, 1.4301 thiab 316L stainless hlau tuav tau tseem ceeb vim lawv cov yam ntxwv tshwj xeeb. Kab lus no tsom rau 1.4301 stainless hlau, ua ib qho kev thov vuam ntawm ob qho ntaub ntawv sib txawv hauv ntau yam kev ua haujlwm rau kev lag luam cov neeg siv khoom.

I. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig ntawm 1.4301 stainless hlau

1.4301 Stainless hlau (sib raug mus rau Suav qeb 06cr19NI10) yog ib tus neeg sawv cev ntawm Austenitic stainless hlau, muaj nuj nqis rau nws tus nqi siab - ua tau zoo thiab versatility. Nws cov tshuaj lom neeg muaj pes tsawg leeg, nrog 18 - 20% chromium cov ntsiab lus thiab}}}. 5%}. Nyob rau hauv chav tsev kub, 1.4301 stainless hlau cov khoom pov puag zoo heev plaw, ua rau nws yooj yim rau cov txheej txheem xws li vuam thiab stamping. Nws yog dav siv nyob rau hauv cov liaj teb xws li archoration kho kom zoo nkauj, cov tshuab noj mov machinery, thiab chav ua noj thiab chav dej.

 

Ii. Kev sib piv ntawm Vuam cov txheej txheem kev ua tau zoo ntawm 1.4301 thiab 316L

1. Kev siv tau ntawm vuam txoj kev

1.4301 Tus Hlau Stainless: Txhawb nqa cov txheej txheem puv - scenared hlau vuam (smws), tungsten inert roj vuam (MIG), thiab hlau inert roj vuam (Mig). Kev siv ntawm e 308 -} cov hluav taws xob tuaj yeem ua tau kom tau raws li cov kev cai ntawm feem ntau ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv cov kws kho kom zoo nkauj vuam, nws yog ib qho yooj yim rau kev ua haujlwm thiab tsim cov khoom siv tsiaj kom zoo nkauj.

316L stainless hlau: txawm hais tias nws tau sib tw nrog cov vuam vuam siv ntau ntxiv rau cov kev pheej hmoo ntawm cov khoom kub - ua kom haum rau cov khoom kub vuam, ua rau nws tsim nyog rau cov cuab yeej siv hluav taws xob vuam.

2. Kev Sib Piv ntawm Ua Ntej - thiab Tshaj Tawm - Vuam Kev Kho Mob

Txheej Txheem Theem	1.4301 stainless hlau	316L stainless hlau
Tos - Kev Npaj Vuam	Niaj zaus ntxuav, tsis tshua muaj preetsing	Preheating ntawm 100 - 150 degree yuav tsum muaj rau cov phiaj tuab
Post - Vuam Kho	Kev kho annealing yog feem ntau tsis tsim nyog	Kev kho kom haum yog yuav tsum tau txhim kho kev ua haujlwm nyob rau hauv kev ua haujlwm nyuaj

III. Cov tseem ceeb hauv Weld Performance

1. Kev sib piv ntawm cov khoom siv mechanical

1.4301 stainless hlau: lub zog tensile ntawm weld sib phim zoo nrog ntawm lub hauv paus hlau, ua rau nws haum rau cov txheej txheem sib xyaw ua ke nyob rau hauv cov khoom siv zoo li qub. Txawm li cas los xij, cov tawv ntawm cov cua sov - thaj chaw cuam tshuam yuav txo qis vim muaj kev kub siab.

316L stainless hlau: nws tswj siab tawv txawm nyob rau hauv tsawg - qhov chaw ntsuas kub, xws li cov hlab ntsha nruj thiab qis - qhov chaw tso dej khov.

2. Tsom xam ntawm corrosion tsis kam

Daim ntawv thov cov xwm txheej ntawm 1.4301: nws ua tau zoo nyob rau hauv cov huab cua qhuav thiab cov khoom siv dej tshiab hauv cov dej sab nraum zoov thiab dej haus pipeline vuam. Txawm li cas los xij, nws pitting corrosion tsis muaj zog hauv cov xov xwm muaj chloride ions.

Qhov zoo ntawm 316L: Ua tsaug rau nws cov Molybdenum cov ntsiab lus xws li cov roj carbon ntau, thiab cov tshuaj lom neeg ua haujlwm zoo li ntawm nws cov khoom lag luam hauv corrosionering ntawm nws cov khoom lag luam zoo tshaj li ntawm 1.4301.

IV. Raug daim ntawv thov raug ntawm 1.4301 stainless hlau

Kho kom zoo nkauj Cov Khoom Kho Kom Zoo Nkauj Teb: Welded rau Fabricate Stainless - Hlau Railings thiab Kab Hlau Rhuav - Phab Ntsa. Nws cov txiaj ntsig zoo weldability thiab du nto sib pab ua kom tiav kev pab txo cov nqi.

Khoom noj khoom haus khoom noj: siv rau kev siv cov khoom lag luam ci thiab cov khoom siv mis nyuj, sib hais sib txuas yog yooj yim.

Chav ua noj thiab chav dej tsev: xws li tog hauv tsev: muaj ntau yam woods, uas cov khoom siv yog welded, ntsuas corrosion tsis kam thiab kev lag luam.

V. Xaiv cov lus qhia: thaum muab qhov tseem ceeb rau 1.4301?

1.4301 Stainless hlau yog qhov kev xaiv zoo tshaj plaws rau kev sib tw ua raws li cov xwm txheej hauv qab no:

Cov kev ua kom ib puag ncig ib puag ncig: nyob rau hauv qhov tsis muaj kev mob siab lossis qib siab - kev ua haujlwm ntxhov siab (xws li khoom noj khoom haus hauv tsev).

Tus nqi - Cov txheej txheem Rhiab: Cov txheej txheem vuam yog qhov yooj yim, thiab cov khoom siv yog kwv yees li 20% {% qis dua li ntawm 316L.

Qhov tseem ceeb ntawm kev ua cov kev yooj yim: Qhov kev xav tau rau Vuam ua ntej, tsis tas yuav ua ntej ua ntej - vuam preheating thiab post - vuam kho.
