Cov qib siab ntawm cov ntsiab lus no paub tseeb tias cov alloy muaj cov tshuaj chloride zoo tshaj plaws thiab kev tiv thaiv corrosion rau cov pa 304/304L thiab 316/316L. Cov alloy muab kev txhim kho kev tiv thaiv zoo rau 316L hauv qhov chaw muaj zog corrosive uas muaj sulfurous media, chlorides, thiab lwm yam halides.
Yooj yim ntawm kev ntxuav
Zoo heev formability
Kev tiv thaiv oxidation
Lub zog siab nrog qhov hnyav
Ib qho kev zam, txawm li cas los xij, muaj zog oxidizing acids xws li nitric acid. Cov alloys uas muaj molybdenum feem ntau tsis ua haujlwm zoo hauv cov cheeb tsam no.
Nws yog siv los tuav cov organic thiab fatty acids kub uas feem ntau muaj nyob rau hauv cov zaub mov thiab tshuaj ua daim ntawv thov. Qhov corrosion kuj ntawm 317 thiab 317L yuav tsum zoo ib yam nyob rau hauv ib puag ncig muab. Txawm hais tias 317L yog me ntsis resistant rau kev ntxhov siab corrosion tawg dua li 304/304L stainless hlau, vim nws cov ntsiab lus molybdenum siab dua, nws tseem raug cuam tshuam. Qhov siab dua chromium, molybdenum thiab nitrogen cov ntsiab lus ntawm 317L txhim khu nws lub peev xwm los tiv thaiv pitting thiab crevice corrosion nyob rau hauv muaj chlorides thiab lwm yam halides.

WELDING
Alloy 317L tuaj yeem nkag tau yooj yim los ntawm cov txheej txheem txheej txheem feem ntau. Kev kho cua sov tom qab vuam yog tsis tsim nyog. Yog tias qhov kawg tsim kub poob qis dua qhov pib no, kev daws teeb meem ntawm 1976 - 2156 degree F (1080 - 1180 degree) yog qhov tsim nyog. Yuav tsum ceev quenching
