Kev Ua Tau Zoo Nta Ntawm 200 Series Stainless Hlau

Kev Ua Tau Zoo Nta Ntawm 200 Series Stainless Hlau

Date:Dec 18, 2018

Ntawd yog, cov qauv siv lead ua muaj ib qho atom ntawm txhua ces kaum ntawm lub voos xwmfab, thiab ib qho atom hauv nruab nrab ntawm txhua lub ntsej muag. thiab ferrite stainless hlau yog qhov rov qab, nws yog cim los ntawm lub cev lub siab lub voos xwm txheej.


Nickel yog ib qho ntawm cov khoom siv feem ntau hauv kev tsim cov qauv crystalline, tab sis vim tias tsis muaj npib tsib xee tom qab Kev Tsov Rog Thoob Ntiaj Teb thib ob, kev siv zog ua kom txo qis ntawm kev siv hlau. Qhov no coj mus rau kev hloov cov npib tsib xee, uas yog siv los tsim ua qee qhov corrosion-resistant austenitic stainless hlau, los ntawm lwm lub ntsiab lus, uas ua rau muaj kev tawm tsam ntawm 200-series stainless hlau.


Nitrogen alloys nyob rau hauv 200-series stainless hlau kuj tseem yuav ua rau lub ntsej muag lub voos xwm txheej hauv lub siab, ua rau muaj kev phom sij chromium nitride thiab nce roj ntxiv. Ntxiv cov manganese tso ntau nitrogen rau kev nyab xeeb ntxiv, tab sis nickel tsis tuaj yeem tshem tawm ntawm 200-series stainless hlau. Yog li no, 200 series stainless hlau yog yam ntxwv ntawm nws cov ntsiab lus nitrogen thiab manganese.


Hauv 80 's, kev tsim khoom thiab xav tau ntawm qis npib tsib xee hlau loj ntxiv, tus nqi ntawm npib tsib xee tau nce ntxiv, tab sis kuj yuav txhawb kev txhim kho ntawm 200 series stainless hlau. Asia tam sim no yog qhov tseem ceeb thiab qhov chaw noj rau 200 series ntawm cov hlau. Kev txhim kho qhov tsis kam ntawm 200 series stainless hlau yog qis dua li ntawm 300 series stainless hlau, uas tiv thaiv qhov taw tes xeb hauv qhov chaw muaj cov dej noo thiab chlorine cov ntsiab lus thiab qhov sib txawv corrosion, ua rau cov kua thiab acidic ib puag ncig tsis haum. Qhov no yog vim tias txhawm rau txo cov ntsiab lus nickel, nws tseem yuav txo cov ntsiab lus chromium thiab corrosion kuj.


200-series stainless hlau muaj kev cuam tshuam zoo heev tiv thaiv thiab ua kom nruj, txawm tias thaum tsawg (lossis tsis tshua kub) kub. Lawv feem ntau nyuaj thiab muaj zog dua 300 tawm daim hlau, feem ntau yog vim lawv cov ntsiab lus nitrogen ntau dua, uas yog lub luag haujlwm ntawm kev txhawb nqa nitrogen. Vim tias lawv yog austenite, stainless hlau hauv 200 thiab 300 series tsis yog sib nqus. Txawm hais tias austenitic stainless hlau yog kim tshaj li nws cov ferrite steel, 200-series stainless hlau yog tseem pheej yig dua 300-series stainless hlau vim nws qis cov ntsiab lus nickel. Txawm li cas los xij, cov molding (ductility) ntawm 200 series stainless hlau yog qis dua li ntawm 300 series stainless hlau (txawm tias qhov no tuaj yeem txhim kho los ntawm kev ntxiv tooj liab).


Hais txog kev siv, kev siv ntau ntawm 200 series stainless hlau yog nqaim dua li ntawm 300 tawm kab hauv cov hlau vim muaj qhov tsis zoo corrosion ntawm cov khoom siv. Nws tsis pom zoo kom siv rau hauv ib puag ncig tshuaj, tab sis tau nkag mus rau ntau yam khoom siv hauv tsev. Qee qhov kev siv ntawm 200 series Stainless hlau muaj xws li: Cov tshuab ntxuav tais diav thiab tshuab ntxhua khaub ncaws, txiav khoom noj thiab khoom siv ua noj, dej tso tsheb sab hauv, sab hauv tsev thiab tsis yog qhov chaw sab nraum zoov, cov khoom noj khoom haus thiab dej haus, tsheb (qauv tsim thiab kho kom zoo nkauj).
