Duplex Stainless hlau kav

Duplex stainless hlau yog hu ua "duplex" vim tias lawv muaj ob-theem microstructure uas muaj cov nplej ntawm ferritic thiab austenitic stainless hlau. Daim duab qhia tau hais tias daj austenitic theem raws li "cov kob" surrounded los ntawm xiav ferritic theem. Thaum duplex stainless hlau yog melted nws solidifies los ntawm cov kua theem mus rau ib tug kiag li ferritic qauv. Raws li cov khoom txias rau chav sov, txog ib nrab ntawm cov nplej ferritic hloov mus rau austenitic nplej ("cov kob"). Qhov tshwm sim yog ib qho microstructure ntawm kwv yees li 50% austenite thiab 50% ferrite.

Super Duplex Stainless HlauTubes Specification

Fabrication ntawm tag nrho cov hlau stainless yuav tsum tau ua nrog cov cuab yeej tshwj xeeb rau cov ntaub ntawv stainless hlau. Cov cuab yeej thiab cov chaw ua haujlwm yuav tsum tau ntxuav kom huv si ua ntej siv. Cov kev ceev faj no yog tsim nyog kom tsis txhob kis kab mob ntawm cov hlau tsis muaj hlau los ntawm cov hlau yooj yim corroded uas yuav ua rau tsis muaj xim ntawm cov khoom fabricated.

Txawm hais tias machinable, lub zog siab ntawm Duplex stainless hlau ua rau machining nyuaj. Piv txwv li, machining ntawm 2205 yog nyob ib ncig ntawm 20% qeeb dua rau 304.
Machining tuaj yeem txhim kho los ntawm kev siv cov cai hauv qab no:

• Txiav ntug yuav tsum tau ceev ceev. Cov npoo dull ua rau kev ua haujlwm hnyav heev.
• Kev txiav yuav tsum yog lub teeb tab sis tob txaus los tiv thaiv kev ua haujlwm nyuaj los ntawm kev caij tsheb ntawm cov khoom siv.
• Chip breakers yuav tsum tau ua hauj lwm los pab kom ntseeg tau tias swarf nyob twj ywm ntshiab ntawm kev ua hauj lwm
• Tsawg thermal conductivity ntawm austenitic alloys ua rau kub siab ntawm cov npoo txiav. Qhov no txhais tau tias cov coolants thiab lubricants yog qhov tsim nyog thiab yuav tsum tau siv ntau heev.
