316 Stainless hlau yeeb nkab
Hais txog 316L stainless hlau yeeb nkab
316L yog qib stainless hlau cov khoom siv, AISI 316L yog cov npe American, thiab sus 316L yog cov npe Japanese.kuv lub teb chaws txoj kev sib koom ua ke digital code yog S31603, tus qauv qib yog 022Cr17Ni12Mo2 (tus qauv tshiab), thiab qib qub yog 00Cr17Ni14Mo2, uas txhais tau hais tias nws tsuas yog muaj Cr, Ni, thiab Mo, thiab tus lej sawv cev rau qhov kwv yees feem pua.
Qhov siab tshaj plaws carbon ntsiab lus ntawm 316 stainless hlau yeeb nkab yog 0.03, uas yuav siv tau nyob rau hauv daim ntawv thov uas annealing tom qab vuam tsis tuaj yeem ua thiab siab tshaj corrosion kuj yuav tsum tau.
316 thiab 317 stainless hlau (saib hauv qab no rau cov khoom ntawm 317 stainless hlau) yog molybdenum-muaj stainless hlau.
Tag nrho cov kev ua tau zoo ntawm qib steel no zoo dua li ntawm 310 thiab 304 stainless hlau.Nyob rau hauv qhov kub thiab txias, thaum cov concentration ntawm sulfuric acid qis dua 15% thiab siab dua 85%, 316 stainless hlau muaj ntau yam kev siv.
316 stainless hlau phaj, tseem hu ua 00Cr17Ni14Mo2 corrosion kuj:
Qhov kev tiv thaiv corrosion yog zoo dua li 304 stainless hlau, thiab nws muaj qhov zoo corrosion kuj nyob rau hauv cov txheej txheem ntawm cov pulp thiab ntawv.
Carbide nag lossis daus tsis kam ntawm 316 stainless hlau yog zoo dua li ntawm 304 stainless hlau, thiab qhov kub thiab txias saum toj no tuaj yeem siv tau.
316l stainless hlau yeeb nkab lub teb chaws tus qauv
316L yog qib stainless hlau cov khoom siv, AISI 316L yog cov npe American, thiab sus 316L yog cov npe Japanese.kuv lub teb chaws txoj kev sib koom ua ke digital code yog S31603, tus qauv qib yog 022Cr17Ni12Mo2 (tus qauv tshiab), thiab qib qub yog 00Cr17Ni14Mo2, uas txhais tau hais tias nws tsuas yog muaj Cr, Ni, thiab Mo, thiab tus lej sawv cev rau qhov kwv yees feem pua.Lub teb chaws tus qauv yog GB / T 20878-2007 (tam sim no version).
316L muaj ntau yam kev siv hauv kev lag luam tshuaj vim nws zoo heev corrosion kuj.316L kuj yog ib qho derivative ntawm 18-8 hom austenitic stainless hlau, nrog 2 mus rau 3% ntawm Mo ntxiv.Raws li 316L, ntau qib steel kuj tau muab los.Piv txwv li, 316Ti yog muab los tom qab ntxiv me me ntawm Ti, 316N yog muab los tom qab ntxiv me me ntawm N, thiab 317L yog muab los ntawm kev nce cov ntsiab lus ntawm Ni thiab Mo.
Feem ntau ntawm 316L uas twb muaj lawm nyob rau hauv kev ua lag luam yog tsim raws li American Standard.Rau cov laj thawj nqi, steel mills feem ntau sim txo cov Ni cov ntsiab lus ntawm lawv cov khoom mus rau qis dua.Cov txheej txheem Asmeskas tau teev tseg tias Ni cov ntsiab lus ntawm 316L yog 10-14%, thaum cov txheej txheem Nyij Pooj tau hais tias Ni cov ntsiab lus ntawm 316L yog 12-15%.Raws li tus qauv yam tsawg kawg nkaus, muaj 2% qhov sib txawv ntawm Ni cov ntsiab lus ntawm Asmeskas tus qauv thiab tus qauv Japanese, uas yog qhov loj heev ntawm tus nqi.Yog li ntawd, cov neeg siv khoom tseem yuav tsum pom kom meej thaum yuav khoom 316L, seb cov khoom xa mus rau ASTM lossis JIS cov qauv.
Cov ntsiab lus Mo ntawm 316L ua rau cov hlau no zoo heev rau pitting corrosion thiab tuaj yeem siv nyab xeeb hauv ib puag ncig uas muaj Cl- thiab lwm yam halogen ions.Txij li thaum 316L feem ntau yog siv rau nws cov khoom siv tshuaj, steel mills muaj qhov yuav tsum tau qis me ntsis rau kev tshuaj xyuas saum npoo ntawm 316L (piv rau 304), thiab cov neeg siv khoom uas xav tau ntau dua saum npoo yuav tsum ntxiv dag zog rau kev tshuaj xyuas saum npoo.
Kev tu thiab tu ntawm stainless hlau
Yog tias cov hlau tsis muaj hlau raug rau huab cua ntev, nws kuj yuav qias neeg zoo li lwm yam.Cov kev tshawb fawb tau pom tias ob txoj kev sib txawv ntawm kev ntxhua khaub ncaws los nag thiab kev ntxuav tes muaj qee yam kev sib raug zoo nrog cov qias neeg ntawm cov hlau tsis huv.Ua ntej, muab ib qho stainless hlau slat nyob rau hauv qhov chaw thiab lwm yam nyob rau hauv lub canopy saib xyuas cov nyhuv ntawm cov nag ntxuav.Cov txheej txheem kev khiav hauj lwm ntawm phau ntawv scouring yog siv ib daim txhuam cev dipped nyob rau hauv xab npum dej los kho qhov chaw ntawm cov khoom siv slats, thiab lub sij hawm yog 6 lub hlis rau kev txhuam.Yog li ntawd, cov slats uas tsis tau ntws tawm hauv lub tsev muaj cov plua plav tsawg dua ntawm qhov chaw ntawm cov slats flushed dua li cov slats uas tau ntws los ntawm ob txoj kev.Yog li ntawd, lub sijhawm tu rau stainless hlau kuj tseem cuam tshuam los ntawm ntau yam.Hauv lub neej, peb tsuas yog ntxuav cov hlau tsis huv thaum peb ntxuav lub khob, tab sis yog tias cov hlau tsis huv sab nraud, nws raug nquahu kom ntxuav nws ob zaug hauv ib xyoos.
