Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4621 / 430 ULTRA

Txhim kho Corrosion Resistance:Cov ntsiab lus chromium siab dua (17-19%) muab kev tiv thaiv corrosion zoo dua li tus qauv 430, nce mus txog 304 hauv ntau qhov chaw, tshwj xeeb tshaj yog tiv thaiv atmospheric corrosion thiab tshuaj me me.

Formability zoo heev:Superior ductility thiab formability piv rau cov qauv ferritic qib, tso cai rau kev sib sib zog nqus nqus thiab ua haujlwm.

Zoo Weldability:Tsawg carbon cov ntsiab lus thiab titanium stabilization txhim kho weldability, txo cov kev pheej hmoo ntawm rhiab heev thiab grain loj hlob.

Txhim kho Surface Finish:Qhov zoo tshaj plaws nto ua rau nws haum rau cov ntaub ntawv kho kom zoo nkauj uas xav tau kev zoo nkauj zoo nkauj.

 

Cov ntawv thov tseem ceeb:

Automotive Trim:Sab nrauv trim, moldings, log npog, thiab cov khoom zoo nkauj.

Cov khoom siv hauv chav ua noj:Lub tshuab ntxuav tais diav pem hauv ntej, lub tub yees panels, qhov cub hauv ob sab phlu, thiab microwave sab hauv.

Architectural Applications:Sab hauv thiab sab nrauv architectural trim, elevator panels, thiab cov khoom zoo nkauj.

Khoom noj khoom haus:Sinks, countertops, thiab cov chaw npaj zaub mov xav tau kev zoo nkauj zoo nkauj.

430 ULTRA (1.4621) piv rau tus qauv 430 (1.4016) thiab 304 (1.4301) li cas?
430 ULTRA muaj kev tiv thaiv corrosion zoo dua li tus qauv 430 vim nws cov ntsiab lus chromium siab dua thiab kev siv tshuaj ntxuav tes. Thaum 430 tuaj yeem pom qhov staining nyob rau hauv nruab nrab corrosive ib puag ncig, 430 ULTRA ua tau zoo nyob rau hauv ntau daim ntawv thov uas 304 ib txwm siv. Nws muaj formability mus txog ntawm 304, ua rau nws haum rau kev sib sib zog nqus nqus dej. Piv rau 304, 430 ULTRA tsis tshua kim thiab tus nqi ntau dua - ruaj khov vim nws cov ntsiab lus qis nickel (tsis muaj nickel ntxiv). Txawm li cas los xij, nws tsis phim 304 qhov kev tiv thaiv corrosion hauv cov tshuaj chloride aggressive thiab yog hlau nplaum. Nws ua haujlwm raws li tus nqi- siv tau zoo rau 304 rau cov ntawv thov uas tsis tas yuav muaj kev tiv thaiv corrosion siab tshaj.

 

Dab tsi yog qhov tsim kev txiav txim siab rau 430 ULTRA?
430 ULTRA muaj cov qauv zoo heev nrog cov duab zoo sib sib zog nqus. Nws qis dua ua haujlwm hardening tus nqi piv rau qib austenitic tso cai rau kev ua haujlwm nyuaj. Cov kev coj ua uas pom zoo muaj xws li:

Siv cov lubrication tsim nyog thaum ua haujlwm

Zam kev deformation ntau dhau hauv kev ua haujlwm ib leeg; multi-theem forming tej zaum yuav xav tau rau cov duab complex

Springback feem ntau qis dua hauv qib austenitic

Annealing tej zaum yuav xav tau tom qab mob hnyav heev los kho ductility

Cov khoom tuav zoo nto zoo tom qab tsim, txo cov kev xav tau ntawm kev ua tiav

 

Dab tsi yog qhov kev txiav txim siab vuam rau 430 ULTRA?
430 ULTRA muaj qhov zoo weldability vim nws cov ntsiab lus carbon tsawg thiab titanium stabilization. Nws tuaj yeem welded siv ntau txoj hauv kev xws li TIG, MIG, thiab tsis kam vuam. Tsawg cua sov input vuam cov tswv yim raug pom zoo kom txo qis kev loj hlob ntawm cov qoob loo hauv tshav kub - cuam tshuam cheeb tsam. Muab cov hlau sib xyaw ua ke muaj, tab sis austenitic fillers zoo li 309L feem ntau siv rau kev ua kom zoo dua. Preheating feem ntau tsis tas yuav tsum tau rau cov ntu nyias. Post-weld annealing tsis tsim nyog rau kev tiv thaiv corrosion, tab sis tej zaum yuav muaj txiaj ntsig zoo rau kev rov ua kom cov ductility hauv qhov txias txias heev - cov khoom ua haujlwm.
