JIS G3114 SMA400BW Weathering Steel
Unlike conventional weathering steels, this JIS G3114 SMA400BW Weathering Steel-certified marvel incorporates Marine-Phase Stabilization Technology™, achieving:
40% greater salt-spray resistance than standard SMA400 grades
Patina stability in 95% RH conditions with 8-hour wet/dry cycles
Unprecedented resistance to microbiologically influenced corrosion (MIC)
Developed through Kobe Steel's Blue Wave Corrosion Control System, SMA400BW features a unique nickel-molybdenum-copper matrix that forms a bi-layer protective film, making it the ultimate choice for:
• Offshore wind farm structures
• Tropical marine bridges
• Coastal industrial complexes
Material Revolution
