en 1.4539 Corrosion Resistance
Ua kom txo cov acids:Vim qhov sib ntxiv ntawm tooj liab, nws pom zoo corrosion kuj nyob rau hauv uas tsis yog -oxidizing acids xws li sulfuric acid, acetic acid, formic acid, thiab phosphoric acid.
Corrosion Resistance nyob rau hauv chloride-Containing Media:Muaj kev ua haujlwm siab rau pitting corrosion thiab ua tau zoo nyob rau hauv nruab nrab chloride- muaj cov xov xwm, cov ntsiab lus siab nickel txo tus nqi corrosion ntawm pits thiab crevices, exhibiting zoo heev crevice corrosion kuj nyob rau hauv cov tshuaj chloride. Nws tseem tuaj yeem tiv taus cov ntsiab lus hydroxide thiab hydrogen sulfide- thaj chaw nplua nuj, thiab muaj zog tiv thaiv kev ntxhov siab corrosion tawg.
Intergranular Corrosion kuj:Cov ntsiab lus qis qis tiv thaiv carbide nag lossis daus tom qab kev kho cua sov thiab vuam, tshem tawm tag nrho cov kev pheej hmoo ntawm intergranular corrosion.
Adaptability rau Lwm Media:Ntawm atmospheric siab, nws tuaj yeem tiv taus acetic acid ntawm txhua qhov concentration thiab kub, nrog rau cov kua qaub sib xyaw ntawm formic acid thiab acetic acid. Nws tuaj yeem siv tau ruaj khov nyob rau hauv sulfuric acid ntawm ntau qhov ntau hauv qab 70 degree, tab sis nws cov corrosion kuj yog qis dua li ntawm siab - alloy steels tsis muaj molybdenum hauv oxidizing nitric acid. Nws siv nyob rau hauv hydrochloric acid yog txwv rau tsawg concentrations ntawm 1-2%.
aisi904l Mechanical thiab Processing Properties
904L Yeeb Nkab qhia cov khoom ruaj khov hauv lub xeev annealed: yam tsawg kawg nkaus tensile lub zog ntawm 71 ksi, nrog zoo elongation thiab toughness, adaptable rau mechanical load yuav tsum nyob rau hauv txawv kev ua hauj lwm.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, nws muaj peev xwm ua tau raws li cov qauv ua xws li stamping, dabtsi yog khoov, thiab shearing, nws muaj zoo welding kev ua tau zoo, sib xws nrog ntau yam welding txoj kev xws li shielded hlau arc vuam (SMAW), roj tungsten arc vuam (GTAW), thiab roj hlau arc vuam (GMAW). Corrosion tsis kam yog rov qab los tom qab vuam yam tsis muaj kev kho cua sov.
astm 904l Kev ua haujlwm siab thiab qis qis
Qhov siab tshaj plaws ua haujlwm kub ntawm 904L Yeeb Nkab tuaj yeem ncav cuag 450 degree. Nws kuj nthuav tawm cov khoom ruaj khov thiab kev tiv thaiv corrosion nyob rau hauv nruab nrab thiab qis - qhov kub thiab txias ib puag ncig, tsis muaj teeb meem qis - kub embrittlement, ua rau nws tsim nyog rau cov ntawv thov kev lag luam thoob plaws qhov kub thiab txias.
