321 stainless hlau yeeb nkab
Kev piav qhia
321 stainless hlau yeeb nkab yog cov yeeb nkab steel ua los ntawm 321 stainless hlau.
1: 321 stainless hlau yeeb nkab.Seamless steel yeeb nkab (GB14976-2002) yog siv los tsim cov kav dej superheated, cov kav dej kub npau npau thiab cov khoom siv boilers ntawm ntau cov qauv rau qis thiab nruab nrab siab boilers, cov pa luam yeeb loj, cov kav dej me me thiab cov kav dej cib.High-quality carbon structural steel kub-kuav los tiag thiab txias-draw (dov) seamless steel kav.
2: 321 stainless hlau yeeb nkab: feem ntau yog siv los tsim cov pa roj carbon zoo, cov qauv hlau alloy thiab stainless hlau kub-resistant seamless steel yeeb nkab rau chav boiler kav nrog siab siab thiab siab dua.Cov kav dej boiler no feem ntau raug rau qhov kub thiab txias.Ua hauj lwm, cov yeeb nkab yuav kuj oxidize thiab corrode nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, yog li cov yeeb nkab steel yuav tsum muaj lub zog ntev, siab oxidation tsis kam, thiab kev ruaj ntseg zoo.
3: 321 stainless hlau tube txais steel tooj: 304321 316 317 310, thiab lwm yam.
4: Alloy structural steel kav nrog qib steel ntawm 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, thiab lwm yam;stainless thiab kub-resistant steel feem ntau siv 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler hlab, ntxiv rau kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom, yuav tsum tau dej pressed ib los ntawm ib tug rau qhov kev xeem, ib tug flaring thiab flattening xeem yuav tsum tau.
5: 321 stainless hlau kav yog xa nyob rau hauv lub tshav kub-kho lub xeev.Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj thiab decarburization txheej ntawm cov yeeb nkab steel tiav.Seamless steel kav rau geological drilling thiab roj drilling tswj;drilling rigs yog siv los tshawb xyuas cov qauv pob zeb hauv av, dej hauv av, roj, natural gas thiab ntxhia.
Kev siv roj thiab cov roj ntuj yog qhov sib cais los ntawm qhov dej drilling.Seamless steel kav rau roj drilling rau geological drilling tswj yog cov cuab yeej tseem ceeb rau drilling, feem ntau suav nrog cov tub ntxhais sab nrauv, cov tub ntxhais hauv yeeb nkab, casing, laum yeeb nkab thiab lwm yam.Vim hais tias cov yeeb nkab drilling yuav tsum nkag mus tob rau hauv qhov tob ntawm ntau kilometers, 1cr5mo alloy yeeb nkab.
6: Cov haujlwm ua haujlwm yog qhov nyuaj heev.Lub laum yeeb nkab tau raug kev nyuaj siab xws li nro, compression, dabtsi yog khoov, torsion thiab unbalanced impact load, thiab tseem raug cov av nkos thiab pob zeb hnav.Yog li ntawd, cov yeeb nkab yuav tsum muaj lub zog txaus, hardness, hnav tsis kam thiab Impact toughness, cov hlau siv rau cov yeeb nkab steel yog sawv cev los ntawm "DZ" (geological Suav Pinyin prefix) ntxiv rau tus naj npawb ib los sawv cev rau cov ntsiab lus ntawm cov hlau.Cov qib steel feem ntau yog 45MnB thiab 50Mn ntawm DZ45;40Mn2 thiab 40Mn2Si ntawm DZ50;40Mn2Mo thiab 40MnVB ntawm DZ55;40MnMoB ntawm DZ60, 27MnMoVB ntawm DZ65.Cov yeeb nkab steel raug xa mus rau hauv cov cua sov kho.
Qhov sib txawv ntawm 321 stainless hlau thiab 304 stainless hlau
321 stainless hlau yog ib qho kev hloov kho ntawm 304 stainless hlau.Qhov sib txawv tseem ceeb ntawm ob yog qhov nce tsib npaug ntawm cov pa roj carbon vim qhov sib ntxiv ntawm titanium.Qhov sib ntxiv ntawm titanium pab tiv thaiv carbide nag lossis daus thaum vuam thiab kub hloov pauv.
Txawm hais tias qhov zoo ntxiv ntawm titanium, 321 tseem muaj ntau yam khoom qub uas ua rau cov hlau tsis muaj steel hauv 300 series zoo heev.Feem ntau siv rau 321 stainless hlau yog annealing, hnyav-lub luag hauj lwm lub tsheb tso tshuab, firewalls, stack liners, aircraft Cheebtsam, thiab lwm yam high-temperature cov khoom siv.
Txoj kev ntxuav ntawm stainless hlau yeeb nkab
1. Txoj kev yooj yim los ntxuav cov hlau tsis huv yog tsuas yog so cov dej kub thiab ib daim ntaub huv si, ces cov hlau qhuav nrog lwm cov ntaub mos muag kom tsis txhob muaj dej me ntsis.
2. Yog tias cov dej zoo tib yam tso qee cov av los yog roj, koj tuaj yeem ntxiv cov tshuaj ntxuav tes me me rau hauv dej.
3. Nws tuaj yeem ntub dej hauv xab npum thiab so nrog daim txhuam cev me me.Nco ntsoov yaug thiab ziab cov hlau tsis huv tom qab ntxuav.
4. Cov roj tuaj yeem yaj tau los ntawm kev txhuam dej cawv ntawm daim ntaub mos.Nws yog ib qho tseem ceeb uas yuav tsum yaug cov cawv thiab qhuav kom nws ci iab hlau tiav.
5. Cov tawv nqaij tawv los yog kub hnyiab tuaj yeem sib xyaw nrog cov dej qab zib thiab dej thiab so nrog cov ntaub mos muag.
