Nkag siab qhov sib txawv ntawm 316L thiab 317L stainless hlau kav
Nkag siab qhov sib txawv ntawm 316L thiab 317L stainless hlau kav
Ob leeg 316L thiab 317L raj yog austenitic stainless hlau, tab sis vim yog siab dua molybdenum, chromium, thiab npib tsib xee cov ntsiab lus, 317L hlab muaj superior corrosion kuj, ua rau lawv zoo tagnrho rau corrosive ib puag ncig xws li flue gas desulfurization thiab ntawv mills . 316L tubes, nrog rau cov ntsiab lus qis dua, zoo moly. chemical, thiab kev siv kho mob, muab qhov sib npaug ntawm tus nqi thiab kev ua haujlwm. Qhov "L" qhia cov ntsiab lus qis carbon, uas txhim kho weldability. Qhov sib txawv tseem ceeb yog tias 317L seamless raj muaj kev tiv thaiv ntau dua rau pitting thiab crevice corrosion nyob rau hauv hnyav acidic / chloride tej yam kev mob, thiab yog li ntawd kim dua 316L steel hlab.
Dab tsi yog qhov tsis zoo ntawm 316L stainless hlau?
Lub ntsiab tsis zoo ntawm 316L stainless hlau suav nrog: tus nqi siab dua piv rau lwm qib (xws li 304); me ntsis qis dua txhua yam lub zog (yield zog) vim nws cov ntsiab lus qis dua, ua rau nws tsis haum rau siab - cov khoom ntxhov siab; susceptibility rau pitting corrosion yog tsis zoo nto kho los yog tswj nyob rau hauv heev corrosive chloride ib puag ncig; thiab muaj peev xwm rau galling thaum ua. Txawm hais tias 316L stainless hlau muaj cov khoom siv vuam zoo, nws cov ntsiab lus qis dua ua rau nws yooj yim dua los ua cov hlau nplaum tom qab ua haujlwm txias piv rau tus qauv 316 stainless hlau.

Corrosion Resistance ntawm 316L thiab 317L Stainless hlau
316L Stainless hlau:
316L muaj qhov zoo tshaj plaws corrosion kuj, tshwj xeeb tshaj yog haum rau ib puag ncig uas muaj kev pheej hmoo ntawm chloride ion corrosion. Nws ua tau zoo nyob rau hauv marine ib puag ncig thiab acidic tej yam kev mob, tab sis tej zaum yuav raug rau lub zos corrosion nyob rau hauv tej yam high -chloride ib puag ncig.
317L Stainless hlau:
317L yog tsim tshwj xeeb rau kev txhim kho corrosion, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig xws li tshuaj nroj tsuag thiab ntawv mills. Qhov siab dua molybdenum thiab npib tsib xee cov ntsiab lus hauv 317L muab kev tiv thaiv zoo rau pitting thiab crevice corrosion, txawm tias nyob rau hauv ib puag ncig hnyav tshuaj muaj chlorides thiab lwm yam corrosive compounds.
Daim ntawv thov ntawm 316L thiab 317L Stainless hlau kav
316L Stainless hlau kav:
