Corrosion Kuj
1.4016 stainless hlau muaj zoo corrosion tsis zoo nyob rau hauv ib txwm atmospheric ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig, tshwj xeeb thiab inorganic tebchaw, tshwj xeeb tshaj tawm tsam nitric acid. Txawm li cas los xij, nws txoj kev tiv taus kuj qis dua li ntawm no 1.440, uas ua tau zoo dua nyob rau hauv kev sib zog nrog cov kab corrorides thiab lwm qhov chaw muaj kev txhim kho ib puag ncig.
Hwj txwv
1.4016 stainless hlau tuaj yeem welded los ntawm cov txheej txheem sib xws, thiab nws cov khoom siv vuam yog qhov ruaj khov. 1.4401 tseem muaj weldability zoo, txawm tias vim nws lub siab thermal conductivity thiab coeffal kev nthuav dav, qhov kub yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev kub ntxhov.
Yog 430 stainless hlau zoo zoo?
Yog, 430 stainless hlau yog qhov kev xaiv zoo rau cov ntawv thov uas xav tau kev ua qoob loo, tshwj xeeb yog cov mob hauv sab hauv tsev thiab cov tsis muaj kev mob siab. Nws tsis tshua kim dua li qib siab xws li 304, thiab yog paub rau nws cov nkauj zoo nkauj thiab kev coj zoo. Txawm li cas los xij, nws txwv tsis kam mus rau ib puag ncig txhoj puab thiab kub ua rau nws tsis tshua tsim nyog rau kev thov cov ntawv thov uas muaj zog thiab kev ua siab ntev yog qhov tseem ceeb.
Cov hlau no feem ntau siv rau hauv cov ntawv thov xws li cov khoom siv, cov khoom siv cookware thiab cov khoom siv zoo nkauj, qhov twg ntev ua rau muaj kev mob corrosive tsis xav tau.
