1.4512 Stainless hlau yog dab tsi?

1.4512 stainless hlau, feem ntau hu ua 409 lossis UNS S40900, yog titanium -stabilized ferritic stainless hlau. Nws muaj kev tiv thaiv zoo corrosion thiab kub tsis kam ntawm tus nqi qis dua li ntau qib austenitic, ua rau nws yog qhov kev xaiv nrov rau kev siv lub tshuab hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam kev siv uas yuav tsum muaj kev tiv thaiv corrosion thiab siab - qhov kub thiab txias.

 

Qhov kev lag luam ferritic qib no yog tus qauv raws li cov npe tseem ceeb thoob ntiaj teb.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4512 / 409

Zoo Kub thiab Corrosion Resistance:Muaj kev tiv thaiv zoo rau oxidation thiab scaling ntawm qhov kub thiab txias (txog li 700 degree) thiab ua haujlwm zoo rau cov pa roj condensate corrosion.

Tus nqi -zoo:Cov ntsiab lus qis nickel ua rau nws muaj kev lag luam ntau dua li austenitic stainless hlau, muab qhov sib npaug ntawm kev ua tau zoo thiab tus nqi rau ntau daim ntawv thov.

Magnetic thiab Weldable:Muaj zog sib nqus nyob rau hauv txhua yam mob. Nws cov qauv ferritic thiab titanium stabilization ua rau nws haum rau vuam, txawm hais tias yuav tsum tau saib xyuas kom tsis txhob muaj cov qoob loo ntau dhau.

 

Cov ntawv thov tseem ceeb:

Automotive Exhaust Systems:Mufflers, catalytic converter plhaub, tailpipes, thiab tso pa tawm manifolds (rau qee qhov kev siv).

Thaum tshav kub kub Exchangers:Cheebtsam hauv automotive thiab industrial cua sov tshuab.

Agricultural Khoom:Cov khoom yuav tsum muaj kev tiv thaiv corrosion tsis zoo.

Cov yam ntxwv ntawm tus qauv:Tsis yog - qhov tseem ceeb architectural thiab industrial qhov chaw uas zoo li tsis yog thawj qhov kev txhawj xeeb.

 

409 (1.4512) piv rau 304 (1.4301) li cas ntawm kev ua tau zoo thiab tus nqi?
Qib 409 tsis tshua kim dua 304 vim nws cov ntsiab lus qis dua (tsis muaj npib tsib xee, qis chromium). Txawm li cas los xij, nws kuj tseem muaj kev tiv thaiv corrosion qis dua, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chloride- muaj ib puag ncig, thiab tsis haum rau cov khoom siv corrosive los yog cov hniav zoo nkauj heev. 409 raug xaiv rau nws cov nqi-kev ua tau zoo thiab kev ua tau zoo hauv qhov tshwj xeeb siab -kub, nruab nrab- daim ntawv thov corrosion zoo li automotive oversp4{9} qhov twg, kim kim.

 

Dab tsi yog qhov txwv ntawm 409 stainless hlau hauv kev siv vuam?
Ua ib tug ferritic stainless hlau, 409 yog ib qho yooj yim rau grain coarsening nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam (HAZ) thaum lub sij hawm vuam, uas yuav txo tau ductility thiab toughness. Yuav kom txo qis qhov no, cov txheej txheem kev siv hluav taws xob qis qis tau pom zoo. Tshaj tawm -weld annealing tuaj yeem pab kho qee qhov ductility tab sis tsis yog ib txwm siv tau. Nws cov ntsiab lus titanium pab txo qis kev cuam tshuam rau intergranular corrosion tom qab vuam, tab sis weld sib koom tsim thiab kev tswj cov txheej txheem tseem ceeb.
