1.4512 Stainless hlau yog dab tsi?

1.4512 stainless hlau, feem ntau hu ua 409 los yog UNS S40900, yog titanium-stabilized ferritic stainless hlau tsim rau cov ntawv thov uas yuav tsum tau oxidation kuj zoo, nruab nrab corrosion kuj, thiab nqi-effectiveness. Nws yog cov khoom siv ua haujlwm rau cov tshuab hluav taws xob tsheb, muab qhov sib npaug zoo ntawm kev ua haujlwm thiab kev lag luam. Nws stabilization nrog titanium txhim kho weldability thiab tsis kam mus rau intergranular corrosion.

 

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

Cov yam ntxwv 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 chromium qis dua thiab tsis muaj npib tsib xee ua rau nws pheej yig dua li austenitic stainless hlau, muab qhov sib npaug ntawm kev ua tau zoo thiab tus nqi.

Stabilized rau Weldability:Titanium ntxiv txo qis carbide nag lossis daus thaum lub sij hawm vuam, txhim kho weld kev ncaj ncees thiab txo qhov cuam tshuam rau intergranular corrosion.

Magnetic thiab Formable:Muaj zog sib nqus nyob rau hauv tag nrho cov mob thiab muaj zoo formability rau manufacturing complex pa system Cheebtsam.

 

Cov ntawv thov tseem ceeb:

Automotive Exhaust Systems:Mufflers, catalytic converter shells, tailpipes, tso pa tawm manifolds, thiab saj zawg zog tubing.

Thaum tshav kub kub Exchangers:Cheebtsam hauv tsheb thiab kev lag luam cua sov tshuab qhov twg kub yog nruab nrab.

Agricultural Khoom:Cov khoom yuav tsum muaj kev tiv thaiv corrosion thiab formability.

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

Transformer thiab Electrical Enclosures:Sib nqus Cheebtsam xav tau qee qhov kev tiv thaiv corrosion.

 

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 corrosive los yog cov ntaub ntawv zoo nkauj heev . 409 muaj zog qis thiab formability tshaj 304 tab sis muaj cov thermal conductivity zoo dua thiab qis dua thermal expansion. Nws yog hlau nplaum, thaum 304 tsis yog -sib nqus. 409 raug xaiv rau nws tus nqi- kev ua tau zoo thiab kev ua haujlwm zoo hauv cov kev kub siab - kub, nruab nrab- daim ntawv thov corrosion xws li automotive exhausts, qhov twg 304 yuav dhau -khoom kim heev thiab tsis tsim nyog.

 

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 thaum vuam, uas yuav txo tau ductility thiab toughness. Txhawm rau txo qhov no, cov txheej txheem kev siv hluav taws xob qis qis tau raug pom zoo, thiab kev xaiv hlau muab tub lim yuav tsum ua raws li daim ntawv thov. Nws titanium stabilization pab txo qis kev cuam tshuam rau intergranular corrosion tom qab vuam, tab sis vuam kev sib koom ua ke tsim thiab kev tswj cov txheej txheem tseem ceeb rau kev tswj cov khoom siv. Rau cov ntawv thov uas xav tau qhov siab tshaj plaws weld, post-weld annealing tej zaum yuav muaj txiaj ntsig tab sis tsis yog ib txwm siv tau hauv qhov chaw tsim khoom.
