Stainless Hlau Qib 409 Annealed Tube Ntawm ASTM A268

Txheem 409 thiab 409L stainless hlau raj thiab yeeb nkab.
Stainless hlau qib 409 Annealed raj ntawm ASTM A268 Stainless hlau qib 409 (UNS S40900)

Txhawb tshuaj

Daim ntaub ntawv

Qib no hom kawm 409 tsis muaj kab tsis muaj dab tsi siv rau:

  • Automotive tso tubing

  • Catalytic hloov tshuab


Tshuaj Formulation

C: = 0.08, Mn: = 1.00, Si: = 1.00, Cr: 10.5 ~ 11.75, Ni: = 0.50, P: = 0.045, S: = 0.03, Ti: (6C ~ 0.75)


Hom 409 steels muaj nyob rau hauv cov ntaub ntawv ruaj khov, xws li S40910, S40920, S40930, uas ruaj khov ntawm kev muab los ntawm muaj cov niobium, titanium nyob rau hauv cov composition.

Taw qhia

409 xim hlau tsis siv lub npe hu ua "cov uas pheej yig tshaj plaws tsis muaj qab hlav".

Nws feem ntau suav hais tias yog raws li lub chromium stainless hlau, uas muaj zoo heev corrosion

ua hauj, kub kub thiab qaug zog kuj. Nws muaj peev xwm paub txog cov pa roj carbon monoxide

rau lub sijhawm ntev thiab lub teeb pom kev zoo.


Stainless Steel Grade 409 Annealed Tube Of ASTM A268


Nrog kub tsis kam, lub cav ua haujlwm tau zoo hauv kev ua haujlwm, tib lub sijhawm,

txo qhov tuab ntawm kev tso pa, yuav txo tau cov pa tsheb. 409 xim hlau tsis muaj

pheej yig dua lwm cov hlau tsis muaj kab, nrog rau kev ua kom zoo, siab yield, yooj yim los hloov, yog

recyclable thiab environmentally phooj ywg tshiab cov ntaub ntawv. Tam sim no, Feem ntau cov npe nrov loj

manufacturers tau siv hom 409 stainless hlau cov ntaub ntawv rau lawv cov khoom.


Cov pa roj carbon tsheb yuav tuaj yeem sau thiab muab pov tseg cov pa tsheb, uas yog kub,

high speed combustion los ntawm lub cav. Tom qab ntawd exhausts pa overboard thiab txo cov suab nrov theem

ntawm qhov siab tshaj tawm cov roj khiav. Lub tshuab tso pa tsheb yog qhov ntev tshaj plaws ntawm pib

qhov twg, uas yuav tsum tau hloov cov kev hloov siab nrawm (ntawm-20 txog rau 850?) thiab siab heev

kev co. Lub 409 stainless steels yuav ua hauj lwm raws li cov cua sov ntawm-20? rau 650 ?.

Tsis ntev los no, raws li lub ntiaj teb nce hnyav chaw, lub luv nrug nroog

tsav tsheb nce, thiab kis ntawm lub caij ntuj no snow remover, tus txheej txheem siv cov pa tua kab yog

tau ntau thiab ntau zog. Los ntawm cov tebchaws Europe? rau cov teb chaws Europe?, cov tsoos hlau tau

tsis tau raws li qhov kev xav tau. Peb kwv yees txhua lub tsheb xav tau 409 tsis muaj kab hlau tsis zoo 35kgs -

65kgs nyob rau hauv lub futuer.


Muaj pes tsawg leeg:

Tshav Kub Kub

Hom 409 xim hlau tsis muaj peev xwm ua haujlwm nyob rau lub sij hawm txog 675? thaum lub sijhawm ua haujlwm tas li, thiab mus txog 815? raws li cov xwm txheej sib txawv. Qhov no tseem ceeb heev rau qhov kev pabcuam rau kev pabcuam.


Tshav Kub Kho

Rau 409 cov hlau tsis muaj hlau, kev ntoj tawm yog kwv yees thaum kub ntawm 790? mus rau 900, tom qab cua txias.


Kev Kawm Vuam

409 tsis muaj cov xim tsis muaj hlau yuav tsum yog pre-rhuab kom txias txog 150 mus 260 ° C ua ntej yuav tsum vuam. Kev tu yuav tsum muab coj los txhuam cov qib 409 steel nrog cua sov, kom txo tau cov khoom noj kom loj tuaj. Txhim kho ntawm cov khoom siv welded tuaj yeem kho tau zoo dua los ntawm kev kub nyhiab tom qab kub ntawm 760 mus rau 815 ° C.
