2507 stainless hlau ntawv yog ferritic-austenitic duplex stainless hlau ntawv nrog ntau chromium thiab molybdenum cov ntsiab lus uas sib txuas cov txiaj ntsig ntawm ferritic thiab austenitic stainless hlau thiab muaj kev tiv thaiv siab rau cov organic acids xws li formic acid, acetic acid, thiab lwm yam organic acids, tshwj xeeb tshaj yog cov uas muaj chlorides. Vim tias 2507 stainless hlau ntawv muaj cov pa roj carbon tsawg heev, nws txo qis qhov ua tau ntawm carbide nag lossis daus hauv intergranular thaum kho cua sov, ua rau nws tiv taus carbide-txog intergranular corrosion. Vim tias qhov tshwm sim ntawm carbide nag lossis daus hauv intergranular thaum kho cua sov yog qhov txo qis, 2507 stainless hlau ntawv muaj qhov ua haujlwm siab rau carbide-txog intergranular corrosion. 2507 stainless hlau ntawv yog ntau resistant rau diluted sulfuric acid nrog chloride ions tshaj 904L stainless hlau ntawv.
Nyob rau hauv txoj cai kev kho mob, lub microstructure ntawm 2507 stainless hlau ntawv muaj ib tug comparatively zoo tagnrho / piv ntawm txog 50/50 duplex qauv, muab nws zoo heev tiv thaiv kev nyuaj siab corrosion rupture, raws li zoo raws li lub zog txhua yam. Thaum cov kua dej kub siab tshaj 1050 degree, tus naj npawb ntawm ferrite theem hauv cov hlau nce nrog qhov kub thiab txias, tab sis vim muaj nitrogen ntau, cov theem piv ntawm cov hlau qis dua 1300 degree tsis txawv ntau. 2507 duplex stainless hlau yog tias tsis yog los ntawm qhov sib txawv ntawm qhov kub thiab txias (los yog los ntawm kev cuam tshuam ntawm tshav kub), yuav muaj 2 tsim thiab δ, χ, R, ' intermetallic theem thiab Cr2N thiab lwm yam oxides nag lossis daus ntawm lub plus matrix, vim cov pa roj carbon tsawg. cov ntsiab lus hauv cov hlau (feem ntau ntawm 0.01 feem pua -0.02 feem pua), yog li feem ntau tsis muaj carbide nyob hauv cov hlau.
