304L – Ultra-Low Carbon 304 Variant: Welded Structure Corrosion Protector

Txheej txheem cej luam

304L yog qhov ultra- qis carbon version ntawm 304 stainless hlau, nrog cov ntsiab lus carbon nruj me ntsis txwv kom tsawg dua lossis sib npaug li 0.03% txhawm rau tshem tawm cov kev pheej hmoo corrosion intergranular. Los ntawm kev txo cov ntsiab lus carbon, nws tiv thaiv cov nag lossis daus ntawm chromium carbides ntawm cov ciam teb thaum lub sij hawm vuam los yog siab - qhov kev pab cuam kub (450-850 degree), zam "chromium depletion" thiab ua kom ntev - lub sij hawm corrosion stability. Nws khaws cia tib yam 18.00-20.00% Cr thiab 8.00-12.00% Ni core muaj pes tsawg leeg raws li 304, tswj kev ua haujlwm zoo heev. Tsis yog-sib nqus, zoo ductile, thiab yooj yim rau weld, nws yog tsim tshwj xeeb rau cov qauv welded loj thiab tuab-section Cheebtsam qhov twg tom qab vuam cua sov kho yog impractical.

Chemical Composition (wt%)

C Less tshaj los yog sib npaug rau 0.03, Si Less tshaj los yog sib npaug rau 1.00, Mn Less tshaj los yog sib npaug rau 2.00, P Less tshaj los yog sib npaug rau 0.040, S Less tshaj los yog sib npaug rau 0.030, Cr: 18.00-20.00, Ni: 8.00-12.00, sib npaug

Tej yam cuab yeej cuab tam (Annealed Condition)

Tensile Strength (Rm): Ntau dua lossis sib npaug li 485 MPa; Yield zog (Rp0.2): Ntau dua lossis sib npaug rau 170 MPa; Elongation (A): Ntau dua lossis sib npaug li 40%; Brinell Hardness (HB): Tsawg dua lossis sib npaug rau 217

Core Zoo

Ultra- cov ntsiab lus carbon tsawg tiv thaiv intergranular corrosion hauv cov pob qij txha welded; tsis muaj ncej-weld kho cua sov xav tau; zoo heev corrosion kuj tau txais los ntawm 304; superior qis-kub toughness; yooj yim rau daim ntawv thiab weld; zoo tagnrho rau loj welded qauv.
