JIS G3114 SMA490CW Weathering Steel

 

 

 

 

 

JIS G3114 SMA490CW represents a specialized category of weathering steel that prioritizes exceptional weldability while maintaining robust atmospheric corrosion resistance. The "CW" designation specifically indicates enhanced performance in welded construction applications, achieved through a carefully balanced chemical composition that incorporates micro-alloying elements including titanium (0.05-0.15%) and niobium (0.005-0.030%). These additions work synergistically with the fundamental weathering elements - copper, chromium, and phosphorus - to create a material that maintains its protective capabilities even after extensive welding operations.
