A789 undist s31803 thiab unsamless tubing
ASTM A240 Hom 2205 Phaj yog lub Duplex phaj yog siv ntau yam kev lag luam xws li kev ua yeeb yam, roj thiab roj kev tshawb nrhiav, thiab marine engineering. Sa 240 gr 2205 daim ntawv yog tsim los ntawm qib 220) stainless hlau, uas yog kev sib xyaw ntawm ferritic thiab ustenitic steel.
Ib txoj kev sib koom ua ke flanged yog tsim ntawm peb cais thiab ywj siab yog tias muaj kev sib cuam tshuam; Cov flanges, lub gaskets, thiab cov bolting; Uas tau sib sau los ntawm kev cuam tshuam lwm tus cuam tshuam, fitter. Cov kev tswj tshwj xeeb yuav tsum muaj nyob rau hauv kev xaiv thiab kev xaiv ntawm tag nrho cov muaj cov ntsiab lus kom muaj kev sib koom ua ke, uas tau siv tau xau nruj.
Kev sib xyaw ua ke ntawm lub zog siab, corrosion tsis kam thiab mob veldability muaj ntau cov txiaj ntsig tab sis kuj coj tsis zoo thiab txwv tsis pub muaj. Lub zog siab yog qhov tsis zoo thaum tsim thiab machining. Lub zog zog kuj txhais tau hais tias cov hlau yog qhov tsawg dua li cov qib tsawg dua Austenitic qib. Qhov no txhais tau tias cov hlau no tsis zoo thaum cov khoom lag luam tsim muaj kev yuav tsum tau ua tiav ntawm kev ua tiav. Nws tseem tsim nyog yog khoov hauv lub siab tias evemem yog tias cov khoom tuaj yeem tsim nyob rau hauv chav steel hlau ntau dua. Qhov metallurgy ntawm ob lub stuplex stainless hlau yog ntau ntau dua li rau cov hlau uas muaj qhov tshwm sim uas lawv nyuaj dua thiab kim heev los tsim khoom. Yuav ua li cas kom muaj tsib xee tsawg dua ntawm cov npib tsib xee nyob rau hauv cov qib kawm tau pab txhawb kom tus nqi qis thiab txo cov nqi volortility.
Duplex stainless hlauyog tsis tshua muaj corrosion tiv taus, ua haujlwm nyuaj alloys. Lawv cov microstructures muaj kev sib xyaw ntawm cov roj av thiab qib ferrite. Raws li qhov tshwm sim, Duplex Stainless hlau tso tawm cov yam ntxwv ntawm ob qho tib si hauv paus dosless thiab ferritic stainless hlau. Qhov kev sib txuam ntawm cov khoom tuaj yeem txhais tau tias qee qhov kev sib cais thaum piv nrog cov qib ntshiab thiab cov qhab nia zoo nkauj.
1.4462 Duplex Stainless hlau yog ib qib zoo heev rau corrosion tsis kam thiab cov khoom siv mechanical. Cov qib kawm no yog sau raws li 1.4462 lossis x2cnimon22-5-3 raws li en cai thiab nws tau sau raws li uns tsis yog kev cai. Qee cov neeg tsim khoom tseem tuaj yeem sau npe qhov no 1.4462 cov khoom siv li dej hiav txwv, Marinox tab sis qhov tseeb, tag nrho cov npe no muaj sib npaug rau cov hlau.
