Kuv yuav ua li cas thiaj nrhiav tau cov qib sib npaug ntawm stainless hlau los ntawm ntau lub teb chaws?
Txhawm rau nrhiav cov qib stainless hlau sib npaug hla cov qauv sib txawv hauv lub tebchaws, siv tus ntoo khaub lig- cov lus qhia zoo li ib qho ntawm nplooj ntawv no. Ua kom koj qib paub (piv txwv li, AISI 304) hauv kab sib txuas, tom qab ntawd nyeem cov kab ntawv kom pom nws cov EN, JIS, GB, DIN, thiab BS sib npaug. Koj tseem tuaj yeem siv qhov tshawb nrhiav los lim los ntawm txhua lub npe qib, UNS tus lej, EN tus lej, lossis tus qauv GB. Rau cov ntawv thov tseem ceeb, ib txwm lees paub qhov sib npaug nrog cov ntaub ntawv raug cai (ASTM A240, EN 10088, JIS G4304, GB / T 4237, BS 970) thiab sab laj nrog koj tus neeg muag khoom.

Dab tsi yog EN sib npaug ntawm AISI 304 stainless hlau?
EN sib npaug ntawm AISI 304 stainless hlau yog EN 1.4301 (tsim X5CrNi18-10). Hauv DIN system, qhov no tseem hu ua Werkstoff Nr. 1.4301. Qhov sib npaug Japanese yog SUS304, thiab Suav GB sib npaug yog 06Cr19Ni10 (yav tas los 0Cr18Ni9). Tag nrho cov npe no xa mus rau tib qib nrog kwv yees li 18% chromium thiab 8% nickel cov ntsiab lus.
Suav GB sib npaug ntawm AISI 316 stainless hlau yog dab tsi?
Suav GB sib npaug ntawm AISI 316 stainless hlau yog 06Cr17Ni12Mo2 (qub npe: 0Cr17Ni12Mo2). Rau 316L, qhov sib npaug GB yog 022Cr17Ni12Mo2 (lub npe qub: 00Cr17Ni12Mo2). Qhov sib npaug EN yog 1.4401 rau 316 thiab 1.4404 rau 316L. Cov npe Japanese JIS yog SUS316 thiab SUS316L feem.
Puas yog SUS304 zoo ib yam li AISI 304?
Yog lawm, SUS304 yog JIS (Japanese Industrial Standards) tsim los rau qib tib yam li AISI 304. Cov "SUS" ua ntej sawv cev rau "Steel Use Stainless" hauv JIS naming system. Ob qhov kev xaiv muaj tib yam tshuaj muaj pes tsawg leeg (kwv yees li 18% chromium, 8% npib tsib xee, Tsawg dua lossis sib npaug li 0.08% carbon) thiab tib UNS tus lej S30400. Lawv yog cov sib hloov tau tag nrho hauv cov khoom specifications.
Dab tsi yog DIN tooj rau 316L stainless hlau?
Tus lej DIN Werkstoff rau 316L stainless hlau yog 1.4404 (tsim X2CrNiMo17-12-2). Txij li cov qauv DIN stainless hlau tau raug hloov pauv ntau los ntawm EN cov qauv (EN 10088 series), qhov no kuj yog tus lej EN. Ib qho kev xaiv EN tus lej 1.4435 (X2CrNiMo18-14-3) kuj qee zaum siv rau 316L nrog ntau qhov sib txawv me ntsis.
Puas yog qib stainless hlau los ntawm cov qauv sib txawv raws nraim tib yam?
Tsis yog. Cov qhab nia sib npaug los ntawm cov qauv sib txawv muaj qhov sib xws tab sis tsis tas yuav tsum muaj cov tshuaj lom neeg sib xyaw thiab cov khoom siv tshuab. Kev tso cai rau cov ntsiab lus xws li carbon, chromium, nickel, thiab molybdenum yuav txawv me ntsis ntawm ASTM, EN, JIS, thiab GB qauv. Piv txwv li, chromium ntau rau "304" yuav yog 18.0-20.0% hauv ASTM tab sis 17.5-19.5% hauv EN. Rau cov ntawv thov tseem ceeb, ib txwm txheeb xyuas qhov muaj pes tsawg leeg txwv tsis pub dhau cov ntaub ntawv tus qauv thiab lees paub nrog koj tus neeg muag khoom.
Cov lus "L" txhais li cas hauv qib stainless hlau zoo li 304L thiab 316L?
Qhov "L" hauv 304L thiab 316L sawv cev rau "Low Carbon." Cov qib no muaj cov ntsiab lus siab tshaj plaws ntawm 0.03% (piv rau 0.08% hauv tus qauv 304 thiab 316). Cov ntsiab lus ntawm cov pa roj carbon tsawg txo qis carbide nag lossis daus (sensitization) thaum lub sij hawm vuam, uas tuaj yeem ua rau intergranular corrosion nyob rau hauv tshav kub- cuam tshuam cheeb tsam. Qhov no ua rau L-qib qhov kev xaiv zoo tshaj plaws rau cov khoom siv welded thiab loj- ntsuas kev tsim kho. Kev lag luam tawm -tawm yog me ntsis qis dua tensile thiab lub zog tawm los piv rau cov qauv qib.
