ASTM A312 UNRONS S30403 Stainless Hlau Seamless Dej Tshuaj Yeeb
ASTM A312 UNRONS S30403 Stainless Hlau Seamless Dej Tshuaj Yeeb
ASTM A312 unders s30403 hais txog kev tshwj xeeb rau 304L stainless hlau yeeb nkab tsim rau kev tsim nyog corrosion thiab high}}} qhov chaw dej haus. The "L" in 304L indicates its low carbon content, which minimizes carbide precipitation during welding, prevents intergranular corrosion, and improves weldability. Lo lus "seamless" qhia tias cov yeeb nkab tau tsim los ntawm ib qho hlau tsis muaj welds, ua rau muaj zog dua thiab cov khaub ncaws sib piv rau welded yeeb nkab.
Dab tsi yog qhov sib txawv ntawm 304 thiab 316 Stainless hlau?
Lub Koom Haum Thawj Sib Txawv yog 316 stainless hlau muaj molybdenum ntxiv, ua rau nws tus nqi qis dua li 304}} zoo li cov khoom siv marine lossis tshuaj chemical. Thaum nws nqa cov nqi siab dua, nws muaj lub neej kev pab ntau dua.
ASTM A312 TP.34L yog qhov qis-} cov roj carbon aus roj carbon monustenitic steel. ASTM A312 TP304L stainless hlau yeeb nkab hlau yog enriched nrog npib tsib xee thiab chromium, txhim kho nws corrosion thiab oxidation tsis kam. Cov kav dej no muab lub zog siab thiab tuaj yeem siv rau hauv high - kev siv ntsuas kub.
ASTM A312 SP304L Seamless Stainless Hlau Yeeb muaj ntau cov khoom siv tsis zoo, suav nrog kev ua kom zoo ntawm cov khoom tsis zoo, thiab lub zog zoo thiab kev ua kom muaj zog ntawm cov kub tsawg.

Cov Nta Tseem Ceeb Ntawm 304L Yeeb
Cov ntsiab lus muaj roj carbon qis (304L): Lub ntsiab lus muaj cov pa roj carbon: Li no "L" ntawm lub npe, tshwj xeeb yog tom qab vuam, tshwj xeeb yog tom qab vuam ib puag ncig.
Seamless manufacturing: Seamless yeeb nkab yog extruded los ntawm ib qho khoom billet, ua rau muaj cov khoom muaj zog, ntau dua cov khoom siv weld.
Corrosion Kuj: raws li Austenitic Stainless hlau, nws muaj kev tiv thaiv zoo heev rau cov corrosion.
Siab -}} Cov ntawv thov kub: Cov khoom siv no yog tsim rau kev tsim cov corrosion thiab siab- Kev siv kub.
Kev Kho Cov Dej Zoo
Lub sijhawm ntev thiab ntev: nws muaj zog corrosion tsis ntseeg txoj kev pabcuam ntev hauv cov dej kho tshuab.
Weldability: cov ntsiab lus carbon tsawg ua rau nws yooj yim rau weld tsis muaj nuj nqi carbide nag lossis zeem muag uas tuaj yeem cuam tshuam corrosion tsis kam.
Du nto: cov khoom siv no tuaj yeem ua polished, muab ib qho chaw du sab hauv rau cov kua dej ua tau zoo thiab muaj ntau ntxiv.
Rov qab siv dua: zoo li lwm cov hlau uas tsis muaj roj av, 304l yog cov khoom siv rov ua dua tshiab.
Gnee steel tshwj xeeb hauv kev tsim khoom thiab muag ntau ntawm cov khoom lag luam ntau ntawm stainless hlau, suav nrog 304, 904, 90205 duplex, thiab 316L stainless hlau. Gnee Steel cov khoom tau siv dav hauv chav ua noj, Aerospace, tshuaj lom neeg, hluav taws xob, thiab lub zog nuclear, thiab lub zog nuclear, thiab hluav taws xob tsis zoo ntxiv. Peb kuj tseem muab kev cai siv steel hlau daws teeb meem rau cov neeg siv khoom xav tau. Rau stainless hlau nqe lossis kev cai ua kev daws teeb meem, thov emailru@gneesteelgroup.comRau cov lus hais.
