Hlau stainless corrosion kev kawm

Stainless hlau 304 thiab instability ntawm NI CR alloy zoo xws li cov muaj peev xwm ua kom muaj thaum nws corrosion. Theem uas chromium carbide ntev cua sov rau cov kub ntau yam yuav cuam tshuam cov alloy 321 thiab 347 hauv corrosive tawm hnyav. Daim ntaub ntawv kub mas siv daim ntaub ntawv kub, muaj siab kuj muaj clear sensitized, kom tsis txhob intergranular corrosion sab sov.
