Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4511 / 430 Ti

Zoo Corrosion Resistance nyob rau hauv ib puag ncig me me:Ua tau zoo nyob rau hauv cov huab cua sab hauv tsev, dej tshiab, thiab tsheb tso pa ib puag ncig, nrog rau kev tiv thaiv zoo dua rau kev cuam tshuam ntawm intergranular dua li qhov tsis ruaj khov 430.

Weldability zoo heev:Lub titanium stabilization txo qis carbide nag lossis daus thaum lub sij hawm vuam, ua rau nws haum rau welded los ua ke yam tsis muaj kev tshaj tawm -weld heat treatment.

Siab -Tub kub Oxidation Resistance:Kev ua haujlwm zoo rau oxidation thiab scaling ntawm qhov kub siab txog li 750 degree, haum rau cov khoom siv hluav taws xob.

Sib nqus thiab nqi-zoo:Muaj zog sib nqus thiab txuag nyiaj ntau dua npib tsib xee- muaj cov qib austenitic, muab qhov sib npaug ntawm kev ua tau zoo thiab tus nqi.

 

Cov ntawv thov tseem ceeb:

Automotive Exhaust Systems:Mufflers, catalytic converter vaj tsev, tailpipes, thiab tshav kub shields.

Thaum tshav kub kub Exchangers:Cheebtsam hauv tsheb thiab HVAC systems yuav tsum tau thermal conductivity zoo.

Kho kom zoo nkauj Trim:Sab hauv thiab sab nrauv architectural ntsiab qhov twg aesthetics thiab nruab nrab corrosion kuj yuav tsum tau.

Cov khoom siv:Lub tshuab ntxuav tais diav sab hauv, qhov cub hauv ob sab phlu, thiab lwm yam khoom siv hauv tsev.

Khoom siv hauv chav ua noj:Sinks, countertops, thiab npaj zaub mov nyob rau hauv ib cheeb tsam uas tsis xav tau.

 

430 Ti (1.4511) piv rau tus qauv 430 (1.4016) li cas?
430 Ti yog titanium-stabilized version ntawm 430 nrog cov khoom zoo dua qub. Qhov sib ntxiv ntawm titanium muab qhov ua tau zoo dua rau kev tiv thaiv intergranular corrosion tom qab vuam lossis siab - qhov kub thiab txias, ua rau nws tsim nyog rau cov khoom siv welded zoo li cov tshuab tso pa. 430 Ti kuj muaj cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.05% vs. Tsawg dua lossis sib npaug li 0.12%), uas ntxiv dag zog rau weldability. Thaum ob qho tib si yog ferritic thiab sib nqus, 430 Ti muab kev txhim kho formability thiab zoo dua weld kev ncaj ncees. Standard 430 tej zaum yuav raug kev txom nyem los ntawm chromium carbide tsim nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam thaum vuam, txwv nws siv nyob rau hauv welded daim ntaub ntawv.

 

Dab tsi yog qhov kev txiav txim siab vuam rau 430 Ti?
430 Ti muaj weldability zoo vim nws 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.

 

Puas yog 430 Ti haum rau kev siv tsheb tso tawm?
Yog lawm, 430 Ti yog dav siv nyob rau hauv automotive tso systems, tshwj xeeb tshaj yog rau cov Cheebtsam ua hauj lwm nyob rau hauv qis kub xws li mufflers thiab tailpipes. Nws cov titanium stabilization muab cov weldability zoo rau cov khoom siv hluav taws xob, thiab nws cov oxidation tsis kam yog tsim nyog rau feem ntau cov pa siv. Nws muaj qhov sib npaug zoo ntawm kev tiv thaiv corrosion, formability, thiab tus nqi -kev ua tau zoo piv rau ob tus qauv 430 thiab siab dua- cov qib alloyed xws li 439 lossis 409. Rau siab dua - qhov kub thiab txias (ze ntawm lub cav), cov qib nrog cov ntsiab lus chromium siab dua yuav xav tau.
