Stainless hlau tau suav hais tias yog ib hom hlau sib txawv thiab siv ntau hauv kev lag luam. Rau cov laj thawj, ntau hom hlau tau tsim, cim raws li cov npe hauv tsev thiab txawv teb chaws.
Cov cuab yeej tseem ceeb ntawm stainless hlau yog nws yuav luag tiav tsis kam los ntawm kev xeb nyob hauv kev cuam tshuam ntawm ntuj oxidation thiab kev tawm tsam ib puag ncig. Qhov tshwj xeeb ntawm cov hlau tsis sib xws yog vim muaj cov ntsiab lus chromium nyob hauv thawj qhov loj me. Tsis tas li, muaj pes tsawg leeg ntawm stainless hlau muaj impurities ntawm npib tsib xee thiab ntau yam ua ke nrog smelting thiab muab cov khoom ntxiv: carbon, manganese, phosphorus, silicon, titanium thiab lwm yam. Ua raws li qhov feem pua ntawm cov tshuaj ntxiv, cov qib steel raug txiav txim siab, uas tau sau tseg raws li Lavxias lossis txawv teb chaws cov qauv.
Stainless hlau npav raws li GOST
Lub teb chaws CIS muaj cov cim kev sib tw tseem ceeb tshaj plaws rau stainless hlau. Ua raws li lub xeev kev tsim qauv ntawm kev tsim khoom, txhua qib ntawm stainless hlau muaj daim ntawv dav dav: 00X11H22M3, qhov twg txhua tsab ntawv qhia tau qhov tshuaj lom neeg, thiab tus lej hauv qab nws txhais cov ntsiab lus ntawm cov khoom no hauv cov alloy. Ntawd yog, steel qib 03X17H14M2 muaj li 17% chromium, 14% npib tsib xee thiab 2% molybdenum. Ntxiv nrog rau cov yeeb tshuaj no, muaj lwm cov khoom sib xyaw hauv cov hlau, cov ntsiab lus meej ntawm cov uas tuaj yeem hais qhia hauv lub rooj tshwj xeeb.
Qib steel hlau raws AISI
Tus qauv Asmeskas tsis tas ib txwm qhia kev sib xyaw ntawm cov ntau hauv cov khoom ntawm lub npe, tab sis tsuas yog txhais tau pab pawg thiab tsev neeg ntawm stainless hlau lossis cov khoom lag luam. Kev nkag thwj toog yog raws li nram no: AISI 304 lossis AISI N08904. Qhov tseeb xa ntawv ntawm cov qib steel thiab lawv muaj pes tsawg leeg tuaj yeem tsim los siv cov rooj tshwj xeeb. Txawm li cas los xij, cov hom phiaj dav dav muaj peb tus lej, thiab cov pib nrog tus ntawv sau ua ntej N lossis S yog cov sib txuas tshwj xeeb uas tsis muaj cov qauv analogues hauv cov qauv tsim qauv hauv tsev.
Cim German ntawm stainless hlau
Lub chaw tsim khoom hauv German cog lus rau cov khoom lag luam cov npe cov npe ntawm stainless hlau qib uas ze rau CIS tus qauv. Tus qauv tsim qauv hu ua DIN, thiab daim ntawv dav dav ntawm lub cim yog kwv yees li cov hauv qab no: X3CrNiMnMoNbN 23-17-5-3. Ntawd yog, thaum pib ntawm kev tsim cov hom ntawm stainless hlau tau qhia, tom qab ntawd cov tshuaj lom neeg uas muaj nyob rau hauv cov alloy nyob rau hauv daim ntawv ntawm impurities tau teev, thiab tom kawg cov ntsiab lus ntawm cov ntsiab lus tau qhia nyob rau hauv tib qho kev txiav txim. uas lawv tau teev tseg.
Stainless hlau nrog cim European
Hauv cov tebchaws nyob sab Europe, qib steel yog xaiv raws li 1.4301. Cov qeb tshwj xeeb hauv steel, piv txwv li, yog piv rau 08X18H10 hauv kev cim kaw lus ntawm cov CIS lub teb chaws. Hauv Tebchaws Europe, nws yog kev coj los qhia tsuas yog txoj cai digital ntawm cov alloy, thiab qhia tseeb txog cov tshuaj lom neeg thiab lub hom phiaj ntawm cov hlau yog txiav txim siab los ntawm txoj kev tabular.
