s316l thiab s310moln Corrosion kuj
- Muaj zog oxidizing acid (sulfuric acid / nitric acid):Tus nqi corrosion yog qis dua ntawm 310moln (xws li<0.1mm/year in 50% sulfuric acid).
- Chloride ion ib puag ncig (seawater / dej ntsev):SS316L zoo dua (corrosion rate<0.05mm/year in 3.5% saltwater).
- Reductive nruab nrab (hydrochloric acid):316L yog corrosion ntau dua -resistant (≈ 0.3mm / xyoo hauv 10% hydrochloric acid). cov
- Post weld corrosion:S316L tsis xav tau kev kho cua sov, thaum 310moln xav tau kev kho mob ntawm 1050-1100 degree.
Machinability, forming, thiab Fabrication Parameters
Rau cov neeg kho tshuab cov neeg cog lus fabricating spools, manifolds, los yog tshav kub exchangers, ua cov yam ntxwv ncaj qha cuam tshuam qhov project nqi zog thiab sij hawm txhuas.
Ua Haujlwm Hardening:Ob qho khoom siv ua haujlwm- tawv sai vim lawv cov qauv austenitic. Txawm li cas los xij, vim tias 310MoLN muaj cov qib siab dua ntawm Chromium, Nickel, thiab Nitrogen, nws nthuav tawm ntau dua shear zog thiab ua haujlwm - hardens sai dua 316L. Heavy-cov cuab yeej ua haujlwm, kev teeb tsa nruj, thiab cov khoom noj zoo tas li yog xav tau thaum machining 310MoLN.
Cold forming:316L muaj qhov tshwj xeeb ductility thiab zam kev zam heev thaum lub caij txias -bending, dov, los yog cov txheej txheem kos duab. 310MoLN tuaj yeem ua tau txias-, tab sis vim nws lub zog ua haujlwm siab dua, nws xav tau ntau dua mechanical force thiab tej zaum yuav xav tau cov tshuaj nruab nrab annealing los txo cov kev ntxhov siab sab hauv.
Daim ntawv thov ntawm ss310moln thiab ss316l
- Tshuaj thiab Petrochemical:Cov nroj tsuag acetic, sulfuric, thiab phosphoric acid, tawg roj quenching systems nyob rau hauv ethylene nroj tsuag thiab organic synthesis txheej txheem uas muaj chlorides.
