347 stainless hlau yeeb nkab tsis kam mus rau intergranular corrosion
Qhov sib ntxiv ntawm columbium nyob rau hauv 347 stainless hlau muab kev tiv thaiv rau rhiab heev thiab intergranular corrosion. Kev hnov mob tshwm sim thaum cov hlau tsis muaj qhov kub thiab txias, ua rau cov nag lossis daus ntawm chromium carbides raws cov ciam teb. Los ntawm kev tiv thaiv qhov no, 347 stainless hlau nthuav tawm kev txhim kho kev sib txhuam corrosion piv rau lwm qib stainless hlau.

Ntawm no yog qhov tseem ceeb ntawm nws cov intergranular corrosion kuj:
1, Kev Tiv Thaiv Kev Tiv Thaiv: Kev hnov mob yog ib qho txheej txheem uas tshwm sim thaum cov hlau tsis muaj hlau raug kub ntawm 800 thiab 1650 degree F (425 txog 900 degree). Thaum lub sij hawm rhiab heev, chromium carbides tuaj yeem precipitate raws cov ciam teb ntawm cov hlau, depleting cov ntsiab lus chromium nyob rau hauv cov cheeb tsam. Qhov chromium depletion no ua rau cov ciam teb ua rau muaj kev cuam tshuam corrosion.
2, Stabilization Effect: Lub xub ntiag ntawm columbium nyob rau hauv 347 stainless hlau muab stabilization tiv thaiv rhiab heev. Columbium tsim cov carbides uas muaj ntau dua solubility rau carbon piv rau chromium carbides. Yog li ntawd, columbium carbides nyiam tsim es tsis txhob chromium carbides raws cov qoob loo. Qhov no tiv thaiv lub depletion ntawm chromium nyob rau hauv lub grain ciam teb, tuav lub corrosion kuj ntawm cov khoom.
3, Intergranular Corrosion Resistance Testing: 347 stainless hlau tau dhau los ntawm ntau yam kev ntsuam xyuas los ntsuas nws cov kev tiv thaiv rau intergranular corrosion. Cov kev sim uas siv ntau tshaj plaws suav nrog ASTM A262 Practice A (Oxalic Acid), ASTM A262 Practice E (Copper-Copper Sulfate), thiab ASTM A262 Practice F (Nitric Acid) tests. Cov kev ntsuam xyuas no ntsuas qhov cuam tshuam ntawm cov khoom mus rau intergranular corrosion los ntawm kev nthuav tawm nws rau ib puag ncig corrosive tshwj xeeb thiab tshuaj xyuas qhov cuam tshuam ntawm corrosion raws cov ciam teb.
