SUS316L stainless hlau yog dab tsi?
SUS316L yog ib qho qis-carbon, molybdenum-cov kabmob austenitic stainless hlau uas ua raws li cov qauv kev lag luam Japanese (JIS).
Nws thawj qhov sib npaug thoob ntiaj teb suav nrog AISI 316L, UNS S31603, EN 1.4404, X2CrNiMo17-12-2, thiab 022Cr17Ni12Mo2. SUS316L tau tsim los ntawm kev ntxiv molybdenum (Mo) rau lub hauv paus muaj pes tsawg leeg ntawm SUS304, uas txhim kho cov khoom zoo xws li kev tiv thaiv chloride corrosion, pitting corrosion, crevice corrosion, thiab corrosion hauv cov qauv welded. Yog li ntawd, SUS316L feem ntau yog xaiv rau cov ntawv thov uas qhov kev tiv thaiv corrosion ntawm SUS304 yuav tsis txaus.

Molybdenum (Mo) cov ntsiab lus ntawm SUS 316L yog dab tsi?
Mo cov ntsiab lus yog 2.0-3.0%. Molybdenum yog lub luag haujlwm tseem ceeb rau pitting thiab chloride tsis kam ntawm 316L; nws nce tus nqi PREN los ntawm 18 (rau 304) mus rau ntau dua 26, ua rau nws qhov kev txiav txim siab xaiv 316L tshaj 304.
Qhov txawv ntawm SUS316L thiab SUS316 yog dab tsi?
Qhov sib txawv tseem ceeb ntawm SUS316L thiab tus qauv SUS316 yog cov ntsiab lus carbon. SUS316L txwv cov pa roj carbon tsawg dua los yog sib npaug li 0.030%, txo qis chromium carbide nag lossis daus thaum vuam thiab txhim kho corrosion kuj nyob rau hauv welded lug. Qhov sib ntxiv ntawm 2-3% molybdenum (Mo) ua kom muaj zog tiv thaiv chloride-induced pitting thiab crevice corrosion.
Dab tsi yog qib sib npaug rau SUS316L?
Tus txheej txheem Japanese siv cov lus ua ntej "SUS," US tus qauv siv "316L," tus qauv European siv "1.4404," thiab Suav tus qauv siv "022Cr17Ni12Mo2."
Hauv cov qauv European, muaj ob qib zoo sib xws: 1.4404 (X2CrNiMo17-12-2) thiab 1.4435 (X2CrNiMo18-14-3). Cov qub muaj cov ntsiab lus npib tsib xee ntawm 12-15%, thaum tom kawg muaj 14-16%; 1.4435 yog qhov kev xaiv siab dua, yog li nws yuav tsum tau qhia meej meej thaum kev yuav khoom.
Thaum tso ib qho kev txiav txim, nco ntsoov paub meej tias tus qauv twg tus neeg xa khoom ua raws li kom tsis txhob muaj teeb meem tshwm sim los ntawm "kev zam sib txawv rau tib qib."

FAQ
Q: Puas yog SUS 316L sib nqus?
Hauv lub xeev annealed, nws feem ntau tsis yog -sib nqus (tsis nyiam cov hlau nplaum); Txawm li cas los xij, magnetism nce ntxiv tom qab cov txheej txheem ua haujlwm txias xws li kos duab lossis stamping. Qhov no yog ib txwm tshwm sim thiab tsis qhia cov khoom impurity.
Q: Puas yog SUS 316L thiab 316L zoo ib yam?
Lawv yeej tseem zoo ib yam, txawm hais tias European tus qauv 1.4404 qhia txog nickel (Ni) ntau ntawm 12-15% (sib piv JIS), thaum ASTM 316L qhia txog 10-14%. Tsis tas li ntawd, European tus qauv 1.4435 (Ni 14–16%) yog qhov siab tshaj -kawg variant uas yuav tsum tau qhia meej meej thaum kev yuav khoom.
Q: Dab tsi yog qhov siab -kub txwv rau SUS 316L?
Kev khiav hauj lwm kub yog kwv yees li -196℃txog 870℃; nws tsis dhau hardening ntawm kev kho cua sov. Kev siv lub sij hawm ntev tshaj 870℃yuav ua rau sigma (σ) theem nag lossis daus, ua rau embrittlement.
Q: Dab tsi yog qhov txawv ntawm cov zaub mov- qib 316L thiab tus qauv 316L?
Khoom noj khoom haus- qib cov khoom siv txwv nruj dua rau cov khoom tsis zoo (xws li txhuas, arsenic, thiab cadmium) thiab cov lus qhia tshwj xeeb; nws yuav tsum ua raws li cov zaub mov- tiv tauj daim ntawv pov thawj (xws li FDA 21 CFR, EU 1935/2004).
Q: Kuv yuav xaiv li cas ntawm SUS 316L thiab 2205 duplex stainless hlau?
2205 muaj kwv yees li ob npaug ntawm lub zog ntawm 316L thiab superior corrosion kuj (PREN ≈ 35), tab sis nws muaj cov weldability tsis zoo thiab cov nqi siab dua . 316L feem ntau txaus rau cov txheej txheem tshuaj los yog marine daim ntaub ntawv, whereas 2205 yog qhov kev xaiv rau scenarios uas muaj corrosion heev thiab kev nyuaj siab.
Q: Puas yog SUS 316L xav tau kev kho mob tom qab vuam?
The "L" grade has an extremely low carbon content, so it generally maintains its corrosion resistance without the need for additional solution treatment. However, for weldments with large thicknesses (>25 mm) lossis cov uas muaj ntau qhov kev hla dhau, ib qho kev tshaj tawm -weld solution treatment (1010–1150 degree, water quench) yog pom zoo kom rov qab kho cov khoom zoo.
