316L (S31603), austenitic stainless hlau raws li molybdenum, muaj kev tiv thaiv zoo dua rau kev xeb, pitting corrosion, thiab crevice corrosion tshaj li cov pa chromium-nickel austenitic alloys xws li 304. Cov alloys muaj ntau dua ductility, kev nyuaj siab corrosion, compressive zog thiab kub tsis kam. Hauv cov ntawv thov uas xav tau kev ua haujlwm zoo dua rau kev ua haujlwm dav dav thiab pitting corrosion, 316L nyiam dua 316 lossis 304L vim tias 316L muaj 2-3 feem pua molybdenum, thaum 304 thiab 316 tsuas muaj 1-2 feem pua molybdenum.
304L alloy thiab 316 thiab 316L tooj liab-nickel-molybdenum alloys kuj muaj cov yam ntxwv ntawm austenitic stainless hlau, uas yog, zoo processability thiab formability.

• 316L automotive sensor twj tso kua mis valve corrosion resistant
Piv nrog rau 18-8 stainless hlau, 316, 316L thiab 317L muaj corrosion kuj zoo dua nyob rau hauv atmospheric ib puag ncig thiab lwm qhov chaw me me. Feem ntau, cov xov xwm uas tsis corrode 18-8 stainless hlau yuav tsis corrode molybdenum-muaj qib. Qhov tsuas yog qhov tshwj xeeb yog oxidizing acids heev, xws li nitric acid, uas molybdenum-muaj stainless hlau tsis tshua muaj resistant.
Hauv cov tshuaj sulfuric acid, 316 thiab 317L muaj kev tiv thaiv corrosion zoo dua li lwm cov qib chromium-nickel. Ob qib muaj kev tiv thaiv corrosion zoo rau cov kev daws teeb meem siab ntawm qhov kub txog li 120 degree F (38 degree). Tau kawg, kev kuaj hauv kev pabcuam yog qhov tseem ceeb, vim tias kev ua haujlwm thiab cov kua qaub paug tuaj yeem cuam tshuam cov nqi corrosion. Ob qib no muaj kev tiv thaiv corrosion zoo dua li lwm hom stainless hlau thaum tsom rau cov roj qaub. Txawm li cas los xij, hauv cov ntawv thov no, cov nyhuv ntawm cov kua qaub concentration ntawm qhov corrosion yog qhov tseem ceeb thiab qhov no yuav tsum tau ua tib zoo xav.
Molybdenum-muaj stainless hlau 316 thiab 317L muaj qee yam kev tiv thaiv corrosion rau ntau lwm qhov chaw. Cov ntaub ntawv corrosion hauv qab no qhia tau hais tias cov alloys pom zoo corrosion kuj nyob rau hauv boiling 20 feem pua phosphoric acid daws. Lawv kuj tau dav siv rau kev ua cov organic acids kub thiab fatty acids. Cov hlau tsis muaj molybdenum feem ntau yog siv rau hauv kev tsim khoom thiab tuav cov khoom noj, tsheb, thiab cov khoom siv tshuaj vim tias cov hlau tsis huv yuav tsum raug txo kom tsawg.
Feem ntau hais lus, nyob rau hauv ib puag ncig ib puag ncig, 316, 316L tuaj yeem suav tias muaj qhov ua tau zoo ib yam li 317L. Tab sis nyob rau hauv ib puag ncig uas yuav ua rau vuam thiab intergranular corrosion nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam, muaj kev zam. Hauv cov xov xwm zoo li no, 316L thiab 317L tau xaiv ntau dua vim tias cov ntsiab lus tsis tshua muaj carbon, uas tuaj yeem txhim kho qhov tsis kam mus rau intergranular corrosion.

• 316L automotive sensor twj tso kua mis valve pitting / crevice corrosion
Ntxiv chromium, molybdenum, thiab nitrogen cov ntsiab lus tuaj yeem txhim kho pitting / crevice corrosion kuj ntawm austenitic stainless hlau nyob rau hauv ib puag ncig ntawm chloride los yog lwm yam halide ions. Pitting corrosion yog xam los ntawm PREN (pitting sib npaug), PRE {{0}} Cr ntxiv rau 3.3Mo ntxiv rau 16N. 316, 316L's PREN=24.2, 304's PREN=19.0, uas qhia tau hais tias 316 (los yog 316L) tau zoo pitting corrosion tsis kam tshaj 304. 317L muaj cov ntsiab lus molybdenum ntawm 31 feem pua, PREN{{ 16}}.7, qhia tias nws muaj pitting corrosion kuj zoo dua 316.
304 stainless hlau yog resistant rau pitting corrosion thiab crevice corrosion nyob rau hauv ib puag ncig dej uas muaj 100ppm chloride. 316 thiab 317L uas muaj molybdenum tiv taus pitting corrosion thiab crevice corrosion nyob rau hauv dej ib puag ncig uas muaj 2000ppm thiab 5000ppm chloride feem. Txawm hais tias ob lub alloys no tau siv nrog qee qhov kev vam meej hauv dej hiav txwv ib puag ncig (19,000ppm chloride), qhov kev siv no tsis pom zoo. Alloy 2507 nrog 4 feem pua molybdenum, 25 feem pua chromium, thiab 7 feem pua nickel yog tsim los siv rau hauv cov dej ntsev. 316l, 317L tsuas yog tsim nyog rau qee qhov kev siv hauv marine ib puag ncig, xws li nkoj qhia kev tsheb nqaj hlau, sab nrauv phab ntsa ntawm cov tsev nyob ze dej hiav txwv, thiab lwm yam. 316l, 317L alloys tsis pom corrosion nyob rau hauv 100-teev 5 feem pua ntsev tshuaj tsuag ( ASTM B117)
