Duplex 2205 VS 316 Stainless hlau

316 stainless hlau yog ib yam khoom siv, dav siv hauv petrochemical, chiv nroj tsuag, nkoj tsim thiab lwm yam lag luam.Daim ntawv thov ntawm duplex steel 2205 tau dhau los ua ntau thiab ntau dua, tshwj xeeb tshaj yog nyob rau hauv cov roj offshore, seawater desalination thiab lwm yam kev lag luam uas yuav tsum muaj corrosion siab heev.Seb siv316 stainless hlau yeeb nkablos yog duplex yeeb nkab yog ib qho teeb meem uas peb cov neeg muas zaub feem ntau ntsib.Kab lus no luv luv qhia txog qhov sib txawv ntawm duplex 2205 thiab 316 stainless hlau.Kuv vam tias nws yuav pab tau koj.

Cov tshuaj sib txawv ntawmTIAB SA 2205thiab 316 SS

316 stainless hlau yog dav siv nyob rau hauv kev lag luam tshuaj vim nws zoo heev corrosion kuj.Nws muaj 2-3% molybdenum keeb, thiab belongs rau derivative ntawm 18-8 austenitic stainless hlau.Raws li rau Duplex 2205, nws tau ntxiv nrog nitrogen los txhim kho nws ib feem corrosion kuj.Thiab cov khoom siv cov ntaub so ntswg hauv ferrite thiab austenite tau nyob txhua ib nrab, tsawg kawg yog ib qho ntawm lawv yuav tsum ncav cuag 30%, uas ua rau nws ua cov yam ntxwv ntawm ferrite thiab austenitic stainless hlau.

Qhov txawv ntawm Duplex 2205 thiab 316 Stainless Hlau

• a) Lub zog tawm ntawm duplex 2205 yog ib zaug siab dua 316L, thiab nws muaj cov yas txaus rau molding.Thiab cov phab ntsa tuab ntawm lub nkoj siab ua los ntawm duplex 2205 yog 30-50% thinner dua li ntawm 316L, uas tuaj yeem txuag tau tus nqi.

• b) Duplex 2205 ua tau zoo heev ntawm kev ntxhov siab corrosion, tshwj xeeb tshaj yog thaum nws siv nyob rau hauv marine ib puag ncig uas muaj chloride ions.Txawm li cas los xij, kev ntxhov siab corrosion yog qhov teeb meem tseem ceeb los daws cov austenitic stainless hlau suav nrog 316L.

• c) Duplex 2205 ua tau zoo corrosion kuj tshaj 316L ua nyob rau hauv ntau qhov nruab nrab.Nws ua tau zoo heev corrosion kuj nyob rau hauv acetic acid, formic acid, thiab txawm yuav ua tau ib tug hloov ntawm austenitic stainless hlau, thiab corrosion resistant alloy.Txawm li cas los xij, xaiv duplex 2205 lossis 316L, nws tseem txiav txim siab los ntawm ib puag ncig kev xav tau thiab tus nqi.

• d) Duplex 2205 muaj lub zog siab thiab zoo tshaj plaws hauv zos corrosion kuj, hnav corrosion kuj thiab corrosion qaug zog kev ua tau zoo, uas zoo dua 316L stainless hlau.

• e) Lub linear expansion coefficient ntawm duplex 2205 yog qis dua 316L, thiab nws yog ze rau carbon steel.Qhov no ua rau duplex 2205 haum rau carbon steel kev twb kev txuas, nqa ib qho tseem ceeb rau engineering.

• f) Tsis muaj teeb meem nws nyob rau hauv qhov kev ua haujlwm zoo lossis zoo li qub, duplex 2205 muaj peev xwm nqus tau ntau dua li 316L, uas coj cov txiaj ntsig zoo thiab cov txiaj ntsig siv tau zoo rau cov khoom siv los yog cov kav dej thaum muaj xwm txheej ceev xws li cuam tshuam, tawg.

Qhov tsis zoo ntawm Duplex 2205

Nrog ntau qhov zoo, duplex 2205 zoo li zoo dua li 316. Txawm li cas los xij, piv nrog 316, duplex 2205 kuj muaj qhov tsis zoo:

• a) Daim ntawv thov ntawm duplex 2205 tsis yog universal los yog ntau haiv neeg li 316L.Piv txwv li, yog hais tias ib tug yuav tsum tau ua hauj lwm nyob rau hauv lub kub hauv qab no 250 degrees rau lub sij hawm ntev, ces tsuas yog 316L stainless hlau yuav muaj peev xwm.

• b) Cov yas toughness ntawm duplex 2205 yog qhov tsis zoo dua li 316L, thiab nws kuj ua haujlwm tsis zoo hauv kev ua haujlwm txias thiab tsim.

• c) Duplex 2205 muaj qhov nruab nrab kub brittleness, thiab kev kho cua sov thiab vuam txheej txheem yuav tsum tau tswj nruj me ntsis, kom tsis txhob muaj teeb meem theem tshwm sim, ua rau kev puas tsuaj.

• d) Piv nrog austenitic stainless hlau, qhov tsis muaj zog ntawm duplex stainless hlau yog tias nws muaj cov ntaub so ntswg ferrite ntau.

Duplex 2205 VS 316 SS Tus Nqi

Qee tus neeg yuav xav tias tus nqi ntawm cov hlau duplex yog siab heev, ntau dua li 316 stainless hlau.Qhov tseeb, nws nyob ntawm cov khoom.

Peb muab ob qho tib si duplex 2205 thiab 316 SS yeeb nkab thiab fittings, txais tos hu rau peb yog tias muaj kev xav tau.
