904L Stainless Hlau Round Tube
904L stainless hlau yeeb nkab yog austenitic stainless hlau nrog zoo corrosion kuj. Vim tias qhov sib ntxiv ntawm 1.5% tooj liab, nws kuj muaj kev tiv thaiv zoo heev tiv thaiv kev txo cov acids xws li sulfuric acid thiab phosphoric acid.
904L alloy yog austenitic stainless hlau nrog cov ntsiab lus alloy siab thiab cov ntsiab lus qis carbon. Cov qauv yog kiag li austenitic thiab tsis yooj yim cuam tshuam los ntawm ya raws ferrite thiab sigma theem. Nws muaj peev xwm tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig sulfuric thiab phosphoric acid, vim nws cov ntsiab lus siab ntawm chromium, nickel, molybdenum thiab tooj liab. Txij li thaum cov ntsiab lus carbon ntawm 904L yog tsawg heev (ntau tshaj 0.020%), yuav tsis muaj carbide nag lossis daus nyob rau hauv ib txwm kub kho thiab vuam. Qhov no tshem tawm txoj kev pheej hmoo ntawm intergranular corrosion uas ib txwm tshwm sim tom qab kev kho cua sov thiab vuam.
Vim muaj cov ntsiab lus ntawm chromium-nickel-molybdenum siab thiab qhov sib ntxiv ntawm tooj liab, 904L stainless hlau kav yuav passivated txawm nyob rau hauv txo ib puag ncig xws li sulfuric acid thiab formic acid. Cov ntsiab lus npib tsib xee siab kuj ua rau tus nqi qis dua hauv lub xeev nquag. Nyob rau hauv cov ntshiab sulfuric acid nyob rau hauv lub concentration ntau ntawm 0 ~ 98%, qhov kev pab cuam kub ntawm 904L yuav siab li 40 degree. Nyob rau hauv ntshiab phosphoric acid nrog ib tug concentration ntawm 0 ~ 85%, nws corrosion kuj yog heev zoo.
Hauv kev lag luam phosphoric acid uas tsim los ntawm cov txheej txheem ntub dej, impurities muaj kev cuam tshuam zoo rau corrosion. Ntawm txhua yam ntawm phosphoric acid, 904L stainless hlau yeeb nkab tau zoo corrosion kuj zoo tib yam stainless hlau yeeb nkab. Nyob rau hauv oxidizing nitric acid heev, qhov corrosion kuj yog qis dua piv rau cov hlau alloyed uas tsis muaj molybdenum. Hauv hydrochloric acid, kev siv 904L stainless hlau yeeb nkab yog txwv kom txo qis ntawm 1-2%. nyob rau hauv no concentration range. Lub corrosion kuj ntawm 904L stainless hlau yeeb nkab yog zoo dua li cov pa stainless hlau.
