Corrosion tsis kam thiab lub ntsiab thov ib puag ncig: 904L yog ib hom austenitic stainless hlau nrog cov pa roj carbon ntsiab lus tsawg thiab alloying hlau siab, uas yog tsim los rau cov huab cua tsis zoo. Nws muaj cov kev txhim kho corrosion zoo dua li 316L thiab 317L, thiab coj mus rau tus nqi thiab kev ua haujlwm, thiab muaj tus nqi ua haujlwm siab. Vim tias qhov sib ntxiv ntawm 1.5% tooj liab, nws muaj cov tshuaj tiv thaiv zoo heev rau kev txo cov kua qaub li sulfuric acid thiab phosphoric acid. Nws tseem muaj cov tshuaj tiv thaiv corrosion zoo heev rau kev ntxhov siab corrosion, pitting corrosion thiab qog kev txhim kho los ntawm chloride ion, thiab muaj cov tsis kam tiv thaiv corrosion intergranular. Hauv cov kab xaim ntawm 0-98%, qhov ntsuas kub ntawm 904L tuaj yeem siab txog 40 ℃. Hauv qhov ntau ntawm 0-85% phosphoric acid, nws qhov kev txhim kho corrosion yog qhov zoo heev. Hauv kev lag luam phosphoric acid tsim los ntawm cov txheej txheem ntub, impurities muaj zog lub zog ntawm kev ua hauj corrosion. Nyob hauv txhua hom phosphoric acid, kev txhim kho corrosion ntawm 904L yog qhov zoo dua li cov hlau tsis muaj zog. Hauv kev muaj zog oxidizing nitric acid, qhov tsis kam ntawm corrosion ntawm 904L steel yog qis dua li ntawm cov hlau loj siab uas tsis muaj molybdenum. Hauv hydrochloric acid, kev siv 904L tsuas yog siv rau kev qis qis ntawm 1-2%. Hauv no concentration ntau. Cov tshuaj tiv thaiv corrosion ntawm 904L yog qhov zoo dua li ntawm cov hlau tsis zoo. 904L hlau muaj qhov zoo tiv thaiv pitting corrosion. Hauv cov kua tshuaj chloride, nws cov laj kab kev txhim kho corrosion lub zog. Lub zog kuj zoo heev. Cov ntsiab lus siab ntawm 904L txo qhov xeb ntawm cov paug hauv cov pawm thiab cov nyom. Ordinary austenitic stainless hlau yuav rhiab rau kev nyuaj siab corrosion hauv thaj chaw chloride nplua nuj thaum qhov kub siab tshaj 60 ℃. Cov kev txiav txim siab tuaj yeem txo los ntawm kev nce qib ntawm cov ntsiab lus nickel ntawm stainless hlau. Vim nws cov ntsiab lus siab nickel, 904L muaj qhov kev nyuaj siab corrosion cracking tsis kam rau hauv cov tshuaj chloride, cov dej muaj zog hydroxide tov thiab hydrogen sulfide nplua nuj ib puag ncig.
