JIS G3114 SMA490CW Weathering Steel

 

 

 

 

 

 

 

As part of the Corten-type steel family, SMA490CW is engineered to form a stable protective oxide layer, or patina, when exposed to outdoor environments. This patina effectively slows down further corrosion, reducing maintenance needs and extending the service life of structures, making it ideal for demanding industrial and civil engineering applications.

 

The "CW" designation indicates optimized corrosion resistance and toughness suitable for moderately aggressive environments. With a nominal yield strength of 490 MPa, SMA490CW is well-suited for heavy-load structural applications, bridges, towers, industrial plants, and architectural projects. Its balance of strength, toughness, and weldability makes it a reliable choice for engineers designing long-lasting outdoor structures.
