SMA400CW steel hlau

Gnee Steel tau muab cov neeg siv khoom tshwj xeeb steel cov ntaub ntawv xws li JIS-SMA400CW Kub Rolled Atmospheric Corrosion Resisting Steels rau Welded Structure thiab precision steel machining kev pab txij li xyoo 2008.
JIS G3114 SMA400CW Corten steel, SMA400CW steel phaj / / Ntawv. SMA400CW qis alloy siab zog atmospheric corrosion resisting hlau.
JIS G3114 SMA400CW Corten steel dav siv hauv huab cua preheater, economizer, railway carriage, ntim khoom, choj tsev, kev tsim kho thiab lwm yam.
Cov specifications:
Thickness: 3mm-150mm
Dav: 30mm-4000mm
Ntev: 1000mm-12000mm
Txuj: ASTM EN10025 JIS GB
