Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4590 / 441

Zoo heev High -Temperature Oxidation Resistance:Cov ntsiab lus chromium siab dua (17-}19%) muab kev tiv thaiv zoo tshaj rau oxidation thiab scaling ntawm qhov kub siab txog li ntawm 850 degree, ua rau nws haum rau cov khoom kub-kawg.

Superior Weldability:Dual stabilization nrog titanium thiab niobium tiv thaiv rhiab heev thaum vuam, tshem tawm qhov xav tau tom qab-weld tshav kub kho thiab ua kom zoo weld kev ncaj ncees.

Zoo Thermal Fatigue Resistance:Kev tiv thaiv zoo heev rau thermal cycling ua rau nws zoo tagnrho rau cov khoom siv rov ua cua sov thiab cua txias.

Zoo Corrosion Resistance:Muaj kev tiv thaiv corrosion zoo dua li 409 thiab 430 nyob rau hauv qhov chaw siv tsheb, tshwj xeeb tshaj yog tawm tsam

gas condensate thiab txoj kev ntsev.

 

Cov ntawv thov tseem ceeb:

Automotive Exhaust Systems:Catalytic converter shells, tso tawm manifolds, kub-kawg Cheebtsam, diesel particulate filters, thiab EGR systems.

High-Tsub siv:Cheebtsam yuav tsum tau oxidation zoo mus txog 850 degree.

Thaum tshav kub kub Exchangers:Automotive thiab industrial heat exchanger Cheebtsam.

Decorative Applications:Architectural trim thiab cladding xav tau zoo formability thiab weldability.

Khoom siv:Cheebtsam yuav tsum muaj kev sib xyaw ua ke ntawm siab - kub lub zog thiab corrosion kuj.

 

441 (1.4590) piv rau 409 (1.4512) thiab 439 (1.4509) li cas?
441 muaj kev ua haujlwm siab tshaj - qhov kub thiab txias piv rau 409 thiab 439. Nrog cov ntsiab lus chromium siab dua (17-19% vs . 10.5-11.7% rau 409 thiab 17-19% rau 439) thiab dual stabilization (Ti + Nb), nws muab cov kev txwv oxidation zoo dua 80 txog 70℃thaum 80 degree. degree. Piv rau 439, 441 muaj kev txhim kho weldability thiab zoo dua thermal qaug zog tiv thaiv vim niobium ntxiv, ua rau nws zoo dua rau cov khoom kub-kawg xws li catalytic converter shells thiab tso pa manifolds . 441 kuj muaj lub zog siab dua ntawm qhov kub siab, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thov rau kev siv lub tshuab pa tawm.

 

Dab tsi yog qhov kev txiav txim siab vuam rau 441 stainless hlau?
441 muaj weldability zoo heev vim nws cov titanium thiab niobium stabilization. Nws tuaj yeem welded siv txhua txoj hauv kev xws li TIG, MIG, thiab tsis kam vuam yam tsis muaj preheating. Muab cov hlau sib xyaw ua ke muaj, tab sis austenitic fillers zoo li 309L feem ntau siv rau kev ua kom zoo dua. 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. Lub dual stabilization tiv thaiv rhiab heev, tshem tawm qhov xav tau rau kev tshaj tawm -weld kho cua sov. Tom qab-vuam tu yog pom zoo kom rov ua kom corrosion.

 

Qhov ntsuas kub li cas yog 441 haum rau?
441 yog qhov tsim nyog rau kev pabcuam txuas ntxiv mus txog li 850℃(1560℃F), ua rau nws zoo tagnrho rau kub -kawg automotive tso tsheb. Rau qhov kev pabcuam cuam tshuam, nws tuaj yeem tiv taus luv luv - lub sijhawm raug rau qhov kub siab dua. Nws tuav zoo oxidation kuj thiab txhua yam khoom nyob rau hauv no ntau yam. Nws zoo heev thermal qaug zog tsis kam ua rau nws tshwj xeeb tshaj yog haum rau cov khoom uas raug thermal cycling, xws li tso pa manifolds thiab catalytic converter plhaub. Rau cov ntawv thov siab dua 900 degree, siab dua - qib alloyed xws li ferritic 446 lossis austenitic 309/310 tej zaum yuav xav tau.
