Khoom taw qhia

409 stainless hlau yog Ferritic hlau uas muaj cov khoom siv kho mob zoo thiab kub-resistant corrosion. Nws yog feem ntau suav hais tias yog chromium stainless hlau, nrog rau cov ntawv thov hauv cov tshuab hluav taws xob ntawm lub tsheb thiab cov ntawv thov uas xav tau weldability.

409 steels kuj muaj nyob rau hauv cov ntaub ntawv ruaj khov, xws li qib S40930, S40920 thiab S40910. Kev ruaj ntseg ntawm cov qib no yog muab los ntawm kev muaj niobium, titanium, los yog ob qho tib si, nyob rau hauv muaj pes tsawg leeg ntawm steels.
