SUS 316L vs SS 316L: Dab tsi yog qhov txawv?

Thaum muas cov hlau tsis muaj corrosion-resistant rau chemical, marine, kev kho mob, los yog zaub mov qib daim ntawv thov, buyers feem ntau nug:Puas yog SUS 316L zoo ib yam li SS 316L? Kuv yuav tsum qhia qhov twg hauv kuv qhov kev txiav txim?

Txawm tiasSUS 316LthiabSWB 316Lxa mus rau tib yam tsawg-carbon austenitic stainless hlau nrog molybdenum, qhov sib txawv yog nyob rau hauv cov qauv txheej txheem, ntawv pov thawj thiab kev yuav khoom. Kev nkag siab txog cov nuances no pab cov neeg yuav khoom kom tsis txhob muaj qhov yuam kev tshwj xeeb, kev pheej hmoo ua raws cai, thiab cov nqi tsis tsim nyog.

SUS 316L yog dab tsi?

SUS 316Lyog lub npe hu uaJapanese Industrial Standard (JIS)rau 316L stainless hlau. Nws tus qauv txhais tau pom nyob rau hauvJIS G4303 / JIS G4304. Nws muaj cov ntsiab lus carbon tsawg (tsawg dua los yog sib npaug li 0.03%), zoo heev tiv thaiv intergranular corrosion thiab superior tsis kam rau pitting corrosion nyob rau hauv ib puag ncig chloride. Nws yog tsim rau cov khoom siv tshuaj, khoom siv hluav taws xob thiab khoom siv hluav taws xob, khoom noj khoom haus thiab dej haus cov kav dej, cov khoom siv kho mob thiab cov khoom siv huv huv.

SS 316L yog dab tsi?

SWB 316Lyog ib qho kev lag luam lossis cov ntsiab lus feem ntau siv hauv kev lag luam thoob ntiaj teb, uas ib txwm hais txog 316L stainless hlau raws li cov qauvASTM/AISI/EN. Nws yog tsim rau roj thiab roj kav thiab fittings, siab hlab ntsha, shipbuilding thiab marine qauv, thiab cov khoom siv tshuaj. Rau cov haujlwm thoob ntiaj teb,SWB 316LFeem ntau yog cov khoom siv zoo dua vim tias ASTM lossis EN cov qauv tau lees paub ntau dua los ntawm cov koom haum soj ntsuam thib peb, EPC cov neeg cog lus, thiab cov koom haum faib.

Puas yog SUS 316L thiab 316L tib yam?

Yog lawm,SUS 316L thiab 316L yog qhov tseem ceeb tib yam khoom siv, tab sis SUS ua raws li Japanese Standards System (JIS), tsis yog ASTM lossis EN cov qauv. Los ntawm kev xav ntawm metallurgical thiab kev ua tau zoo, SUS 316L thiab ASTM 316L muaj tib yam corrosion kuj, weldability thiab txhua yam khoom. Qhov txawv yog nyob rau hauv lub npe ntawm tus qauv thiab cov ntawv pov thawj, tsis yog nyob rau hauv qhov zoo ntawm cov khoom.

Chemical Comparison SUS 316L vs SS 316L (Tus nqi zoo, %)

Ob leeg SS 316 thiab 316L qhia cov qib zoo sib xws ntawm chromium (16–18%), npib tsib xee (10–14%), thiab molybdenum (2–3%) rau kev tiv thaiv corrosion zoo dua. Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon: 316 muaj qhov siab tshaj plaws ntawm 0.08% carbon, thaum 316L (tsawg carbon) raug txwv rau qhov siab tshaj plaws ntawm 0.030% txhawm rau txhim kho weldability thiab tiv thaiv intergranular corrosion.

Mechanical Properties SUS 316L vs SS 316L (Annealed Condition)

Qhov tseem ceeb sib txawv rau cov neeg yuav khoom

Puas yog SUS 316L zoo dua SS 316L?

Hais txog kev ua haujlwm,SUS 316L tsis yog qhov zoo dua li SS 316L. Ob qib muaj zog tensile zoo sib xws (Ntau dua lossis sib npaug ntawm 485 MPa), lub zog tawm los (Ntau dua lossis sib npaug ntawm 170 MPa) thiab elongation (Ntau dua lossis sib npaug li 40%) hauv lub xeev annealed, thiab ob qho tib si muaj kev tiv thaiv zoo heev rau pitting thiab crevice corrosion hauv chloride ib puag ncig.

Qhov sib txawv tseem ceeb yog nyob rau hauv ib puag ncig kev thov:SUS 316Lyog tsim nyog rau tej yaam num uas ua raws li JIS cov qauv, tshwj xeeb tshaj yog nyob rau hauv Nyiv thiab ib feem ntawm Asia, thaumSS 316L (ASTM / EN)Nws yog feem ntau siv rau cov haujlwm thoob ntiaj teb uas xav tau kev tshuaj xyuas thib peb lossis ua raws li cov qauv thoob ntiaj teb.

SUS 316L puas tuaj yeem siv rau hauv kev kho mob lossis khoom noj khoom haus?

Yog lawm, vim nws cov ntsiab lus qis carbon thiab siab molybdenum cov ntsiab lus,SUS 316LNws muaj kev tiv thaiv corrosion zoo heev thiab kev tu cev, yog li nws tau siv dav hauv kev kho mob thiab khoom noj khoom haus qib. Hauv daim ntawv thov kev kho mob, SUS 316L feem ntau yog siv rau hauv cov cuab yeej phais, kho mob catheters thiab cov khoom uas tsis yog cog rau qhov chaw uas tsis muaj tshuaj tua kab mob thiab rov ua kom huv yog qhov tseem ceeb.

Hauv kev ua zaub mov thiab dej haus, cov khoom ua tau raws li cov kev cai tu cev thaum cov txheej txheem kho kom zoo (piv txwv li B, BA lossis electropolishing) yog siv, feem ntau ua tiav qhov roughness qhov tseem ceeb ntawmRa Tsawg dua lossis sib npaug li 0.8 µm.
