Corten-B huab cua-resistant steel phaj yog lwm hom huab cua-resistant structural steel phaj, zoo ib yam nyob rau hauv alloy muaj pes tsawg leeg rau Corten-A tab sis muaj cov ntsiab lus carbon ntau dua.
Corten-B huab cua-resistant steel phaj nthuav tawm zoo dua corrosion kuj thiab cov khoom siv kho tshuab, haum rau cov huab cua hnyav dua.
Cov hlau qib Corten B ua tau raws li ASTM cov qauv, nrog cov txiaj ntsig zoo ntawm 355 MPa thiab 345 MPa nyob ntawm qhov tuab.
Corten B muaj nyob rau hauv thickness 2.00-40.00 hli thiab dav txog li 1860 hli raws li kauj, slit coil thiab txiav kom ntev thiab 3300 hli raws li phaj. Ntev mus txog 15 meters raws li txiav mus rau ntev thiab 13 meters raws li phaj.

Lub zog cuam tshuam yog txiav txim siab ntawm ISO-V longitudinal test qauv ntawm qhov kub ntawm - 20 degree raws li qhov nruab nrab ntawm peb qhov kev xeem. Rau cov khoom thicknesses Ntau tshaj los yog sib npaug rau 10mm tus nqi nruab nrab yog tsawg kawg yog 27 J. Rau thicknesses ntawm 10mm thiab 6mm, qhov tsawg kawg nkaus tus nqi yog txo proportionally rau cov qauv dav (khoom thickness).
