317L (1.4438) General Property
Alloy 317LMN thiab 317L yog molybdenum-cov kabmob austenitic stainless hlau raj uas muaj zog tiv thaiv tshuaj tua kab mob zoo li piv rau cov pa chromium-nickel austenitic stainless hlau yeeb nkab xws li Alloy 304. Tsis tas li ntawd, 317LMN thiab 317L alloys muab siab dua creep, kev nyuaj siab-to. -rupture, thiab tensile zog ntawm qhov kub siab tshaj li cov pa stainless hlau. Tag nrho cov qis carbon lossis "L" qib los muab kev tiv thaiv rau kev nkag siab thaum vuam thiab lwm yam txheej txheem thermal.
Cov npe "M" thiab "N" qhia tau hais tias cov khoom xyaw muaj cov qib molybdenum thiab nitrogen ntau ntxiv. Kev sib xyaw ntawm molybdenum thiab nitrogen yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev txhim kho pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem kwj uas muaj cov kua qaub, chlorides, thiab sulfur compounds ntawm qhov kub siab. Nitrogen kuj ua haujlwm kom muaj zog ntawm cov hlau no. Ob lub alloys yog npaj rau kev pabcuam hnyav xws li flue gas desulfurization (FGD) systems.
Ntxiv rau qhov zoo tshaj plaws corrosion kuj thiab lub zog lub zog, Alloys 316, 316L, thiab 317L Cr-Ni-Mo alloys kuj muab cov ntaub ntawv zoo heev thiab formability uas yog ib yam ntawm cov austenitic stainless hlau tubing.
317L (1.4438) Kev kho cua sovAnnealing
Lub austenitic stainless hlau yeeb nkab yog muab nyob rau hauv lub zeb annealed mob npaj rau siv. Kev kho cua sov yuav tsim nyog thaum lub sij hawm los yog tom qab kev tsim kho kom tshem tawm cov teeb meem ntawm qhov txias txias los yog kom yaj cov chromium carbides precipitated los ntawm thermal raug. Rau cov Alloys 316 thiab 317L cov tshuaj anneal yog ua tiav los ntawm cua sov hauv 1900 txog 2150 ° F (1040 txog 1175 ° C) qhov kub thiab txias ua raws li cua txias lossis dej quench, nyob ntawm qhov tuab ntawm seem. Cov cua txias yuav tsum tau ceev txaus los ntawm 1500 txog 800 ° F (816 txog 427 ° C) ntau yam kom tsis txhob rov ua dua ntawm chromium carbides thiab muab qhov zoo tshaj plaws corrosion kuj. Nyob rau hauv txhua rooj plaub, cov hlau yuav tsum tau txias los ntawm annealing kub rau dub kub nyob rau hauv tsawg tshaj li peb feeb.
Forging
Qhov pom zoo pib qhov kub thiab txias yog 2100-2200 ° F (1150-1205 ° C) nrog qhov ua tiav ntawm 1700-1750 ° F (927-955 ° C).
Annealing
317LMN thiab Alloy 317L stainless hlau tuaj yeem muab tso rau hauv qhov kub ntawm 1975-2150 ° F (1080-1175 ° C) ua raws li cua txias lossis dej quench, nyob ntawm qhov tuab. Cov phaj yuav tsum tau muab tshem tawm ntawm 2100 ° F (1150 ° C) thiab 2150 ° F (1175 ° C). Cov hlau yuav tsum tau txias los ntawm qhov kub thiab txias (los ntawm liab / dawb mus rau dub) tsawg dua peb feeb.
Hardenability
- Cov qib no tsis tuaj yeem ua kom tawv nqaij los ntawm kev kho cua sov.
- Alloys 316 thiab 317L stainless hlau raj tsis tuaj yeem hardened los ntawm kev kho cua sov.
