Product Description

Product details

S30403:

S30403 austenitic yooj yim steel, dav siv, zoo heev corrosion kuj thiab tshav kub tsis kam, tsis tshua muaj kub lub zog thiab txhua yam khoom, ib-theem austenite qauv, tsis muaj kev kho cua sov hardening tshwm sim (tsis-sib nqus, kev pab kub -196-800C). Nrog rau tag nrho cov yam ntxwv ntawm SUS304, nws muaj zoo heev corrosion kuj thiab kub tsis kam; Tom qab vuam lossis kev ntxhov siab, nws tuaj yeem tswj tau zoo corrosion kuj, sib sib zog nqus nqus, thiab polishing zoo heev. Nws cov ntsiab lus carbon tsawg thiab nws yog qhov txawv ntawm 304 stainless hlau. S30403 Hlau hmoov txhaj tshuaj molded qhov chaw yog siv nyob rau hauv lub sij hawm uas yuav tsum tau vuam. Cov ntsiab lus qis dua txo qis cov nag lossis daus ntawm carbides nyob rau hauv thaj chaw uas muaj kev kub ntxhov nyob ze ntawm qhov vuam, thiab nag lossis daus ntawm carbides yuav ua rau muaj kev cuam tshuam ntawm intergranular corrosion (welding corrosion) ntawm stainless hlau hauv qee qhov chaw.

Classification ntawm stainless hlau cov ntaub ntawv

304 yog lub hom phiaj dav dav hlau stainless, uas yog siv dav hauv kev tsim cov khoom siv thiab cov khoom uas xav tau kev ua haujlwm zoo tag nrho (corrosion resistance and formability).

301 stainless hlau qhia pom tseeb ua haujlwm nyuaj tshwm sim thaum lub sijhawm deformation, thiab siv rau ntau lub sijhawm uas xav tau lub zog ntau dua.

302 stainless hlau yog qhov tseem ceeb ntawm 304 stainless hlau nrog cov ntsiab lus carbon ntau dua, uas tuaj yeem txias-dov kom tau txais lub zog ntau dua.

302B yog cov hlau tsis muaj hlau uas muaj cov ntsiab lus silicon siab, uas muaj kev tiv thaiv siab kub oxidation.

303 thiab 303Se yog dawb-txiav stainless steels uas muaj leej faj thiab selenium feem, thiab yog siv nyob rau hauv tej lub sij hawm uas yooj yim txiav thiab siab nto tag yog tsuas yog yuav tsum tau. 303Se stainless hlau kuj tseem siv los ua qhov chaw uas yuav tsum tau kub taub hau, vim tias nyob rau hauv cov xwm txheej zoo li no, cov hlau tsis zoo no muaj qhov ua haujlwm kub kub.

304L yog qhov sib txawv ntawm 304 stainless hlau nrog cov ntsiab lus qis dua thiab siv qhov vuam yuav tsum tau ua. Cov ntsiab lus ntawm cov pa roj carbon tsawg tsawg txo cov nag lossis daus ntawm carbides nyob rau hauv thaj chaw uas muaj kev kub ntxhov nyob ze ntawm qhov vuam, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm intergranular corrosion (weld nres) hauv cov hlau tsis muaj steel hauv qee qhov chaw.

304N yog cov hlau tsis muaj nitrogen, thiab nitrogen ntxiv ntxiv kom muaj zog ntawm cov hlau.

305 thiab 384 stainless hlau muaj cov ntsiab lus nickel siab thiab ua haujlwm qis qis, yog li lawv tsim nyog rau ntau lub sijhawm uas yuav tsum tau ua kom txias txias.

308 stainless hlau yog siv los ua welding rods.

Cov ntsiab lus ntawm nickel thiab chromium hauv 309, 310, 314 thiab 330 stainless hlau yog qhov siab, txhawm rau txhim kho oxidation tsis kam thiab creep lub zog ntawm cov hlau ntawm qhov kub thiab txias. 309S thiab 310S yog qhov txawv ntawm 309 thiab 310 stainless hlau, tab sis qhov txawv yog tias cov ntsiab lus carbon tsawg dua, txhawm rau txo qis nag lossis daus ntawm carbides ze ntawm qhov vuam. 330 stainless hlau muaj qhov tshwj xeeb siab ua haujlwm rau carburization thiab thermal shock resistance.

Hom 316 thiab 317 stainless hlau muaj molybdenum, yog li lawv tsis kam rau pitting corrosion nyob rau hauv marine thiab chemical industrial cheeb tsam yog zoo dua li ntawm 304 stainless hlau. Ntawm lawv, 316 stainless hlau variants muaj xws li qis-carbon stainless hlau 316L thiab nitrogen-muaj zog stainless hlau.

316N thiab dawb-txiav stainless hlau 316F nrog cov ntsiab lus sulfur siab.

321, 347 thiab 348 yog stainless hlau stabilized nrog titanium, niobium ntxiv rau tantalum, thiab niobium feem, thiab yog haum rau vuam Cheebtsam siv nyob rau hauv high kub. 348 yog stainless hlau haum rau kev lag luam hluav taws xob nuclear, uas muaj qee yam kev txwv ntawm cov ntsiab lus ntawm tantalum thiab niobium.

304L stainless hlau muaj kev ua haujlwm tsis zoo thiab tsis yooj yim rau deform.

vim ua hauj lwm hardening. Yog li ntawd tus nqi ntawm deformation nyob rau hauv tus txheej txheem ntawm mandrel elongation tsis tuaj yeem muab ntau dhau. Thiab qhov kub poob yog loj dua. Yog li ntawd, nws yuav tsum tau molded nyob rau hauv ntau qhov hluav taws kub. Yog hais tias qhov kub kub rwb thaiv tsev theem tsis ua haujlwm zoo, nws yuav ua rau cov nplej ntxhib.
