Dab tsi yog 304 Stainless Hlau Sawb?

304 stainless hlau sawb yog ib qho ntawm feem ntau siv austenitic stainless hlau cov ntaub ntawv hauv kev tsim khoom. Nws yog tsim los ntawm chromium (18-20%) thiab npib tsib xee (8-10.5%), uas muab qhov sib npaug zoo ntawm corrosion kuj, formability, thiab mechanical zog.

Raws li tau hais tseg raws li cov qauv thoob ntiaj teb xws liASTM A 240 Cov Lus QhiathiabASTM A666 Cov khoom lag luam, 304 stainless hlau sawb yog tsim los ntawm precision txias dov rau hauv nyias, tiaj tus coil daim ntawv. Cov strips no tau siv dav hauv kev lag luam uas xav tau cov tuab tuab, du nto zoo, thiab txhim khu kev qha kev ua haujlwm.

Tsis zoo li dav dav - lub hom phiaj hlau, 304 stainless hlau tswj kev ruaj ntseg nyob rau hauv ntau qhov chaw, nrog rau cov av noo, acidic, thiab corrosive me ntsis, ua rau nws yog ib qho kev xaiv rau ob qho tib si kev lag luam thiab kev lag luam.

Tshuaj muaj pes tsawg leeg ntawm 304 Stainless Hlau Sawb

Kev ua tau zoo ntawm 304 stainless hlau sawb yog txiav txim siab los ntawm nws ua tib zoo sib npaug tshuaj muaj pes tsawg leeg:

Kev sib xyaw ua ke ntawm chromium thiab npib tsib xee tsim cov txheej txheem ruaj khov ntawm cov hlau nto, uas ua kom muaj zog tiv thaiv xeb thiab oxidation.

Mechanical Properties thiab Engineering Performance

Los ntawm qhov kev xav ntawm engineering, 304 stainless hlau sawb muaj qhov sib npaug ntawm qhov muaj zog thiab ductility. Tej yam khoom muaj xws li:

• Tensile zog: 515-750 MPa

• Yield zog: Ntau dua los yog sib npaug rau 205 MPa

• Elongation: Ntau dua lossis sib npaug li 40%

• Hardness: Tsawg dua los yog sib npaug rau 92 HRB

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm 304 stainless hlau yog nws lub peev xwm los ua kom pom kev sib sib zog nqus thiab kev ua haujlwm nyuaj yam tsis muaj kev tawg. Qhov no ua rau nws tsim nyog rau precision stamping, automotive Cheebtsam, thiab hluav taws xob kho vajtse tsim.

Txawm tias tom qab ua haujlwm txias, cov khoom khaws cia zoo toughness, txawm tias me ntsis sib nqus cov khoom tuaj yeem txhim kho vim muaj kev hloov pauv hauv cov theem austenitic.

Txheej txheem tsim khoom: Vim li cas Cold Rolling Matters

304 stainless hlau sawb feem ntau yog tsim los ntawm cov txheej txheem txias dov, uas txhim kho qhov tseeb qhov tseeb thiab qhov chaw zoo.

Cov kauj ruam tseem ceeb ntawm kev tsim khoom muaj xws li:

• Kub dov stainless hlau slabs

• Annealing los txo cov kev ntxhov siab sab hauv

• Txias dov kom ua tiav cov tuab tuab

• Pickling kom tshem tawm cov oxides saum npoo

• Thaum kawg annealing thiab nto finishing

Txias dov yog qhov tseem ceeb tshwj xeeb vim tias nws tso cai rau cov neeg tsim khoom kom ua tiav cov tuab tuab (feem ntau nyob rau hauv ± 0.01-0.05 hli), uas yog qhov tseem ceeb rau kev lag luam xws li hluav taws xob thiab kev ua haujlwm siab.

Nto Finishes thiab Industrial Applications

Qhov nto tiav ntawm 304 stainless hlau sawb ncaj qha cuam tshuam rau nws daim ntawv thov kev ua haujlwm:

2B tiav- Smooth, matte nto siv hauv kev tsim thiab kev tsim khoom

BA (Zoo Annealed)- Lub ntsej muag zoo heev siv hauv cov khoom siv hluav taws xob thiab cov khoom siv kho kom zoo nkauj

Polished tiav- Siv nyob rau hauv precision Cheebtsam thiab pom architectural qhov chaw

Txhua qhov ua tiav raug xaiv raws li qhov yuav tsum tau ua xws li kev tiv thaiv corrosion, kev xav tau zoo nkauj, thiab cov txheej txheem fabrication.

304 vs 304L vs 316 Stainless Hlau Sawb

Kev nkag siab txog qib sib txawv yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog:

Ntawm cov no, 304 tseem yog tus nqi tshaj plaws - qib siv tau zoo thiab siv dav vim nws qhov kev ua tau zoo thiab muaj nyob.
