JIS G3114 SMA490AW Weathering Steel

 

 

 

 

 

JIS G3114 SMA490AW is a high-strength weathering steel grade developed under the Japanese Industrial Standard (JIS). It belongs to the atmospheric corrosion-resistant steel family, engineered to provide superior durability and resistance to outdoor environments. By incorporating small amounts of alloying elements such as copper, chromium, nickel, and phosphorus, SMA490AW develops a dense protective patina when exposed to the atmosphere. This natural oxide layer prevents further corrosion, significantly reducing maintenance costs and extending the lifespan of structures.

 

Compared to conventional carbon steel, SMA490AW offers both higher strength and improved corrosion resistance, making it an excellent choice for heavy-duty structural and engineering applications.
