317L Stainless hlau

General Properties
Alloy 317L (UNS S31703) yog ib qho qis carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless hlau. 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 qib. 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.

Cov ntsiab lus tsis tshua muaj carbon ntawm Alloy 317L ua rau nws yuav tsum tau welded yam tsis muaj intergranular corrosion tshwm sim los ntawm chromium carbide nag lossis daus ua rau nws siv tau rau hauv cov xwm txheej zoo li welded. Nrog rau qhov sib ntxiv ntawm nitrogen ua tus neeg sawv cev ntxiv dag zog, cov hlau tuaj yeem raug lees paub raws li Alloy 317 (UNS S31700).

Alloy 317L yog non-magnetic nyob rau hauv lub annealed mob. Nws tsis tuaj yeem hardened los ntawm kev kho cua sov, txawm li cas los xij cov khoom yuav tawv vim ua haujlwm txias. Alloy 317L tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw.
