Products Description
SMA400AW is a high-performance weathering steel alloyed with copper, chromium, and nickel. Its notable feature is the ability to form a stable protective rust layer in various atmospheric environments, including urban, industrial, coastal, and rural areas, effectively resisting corrosion from moisture, salt spray, pollutants, and acidic gases.
As a hot-rolled atmospheric corrosion-resistant steel plate, SMA400AW not only offers excellent strength and toughness but also outstanding weldability and machinability.
The addition of phosphorus enhances its weathering resistance and makes it highly reliable for applications such as flue ducts, boiler shells, bridges, and outdoor building structures where long-term corrosion protection is required.
Compared to ordinary carbon steel, SMA400AW provides significant advantages in service life, maintenance costs, and aesthetic appearance, reducing the need for frequent coatings and offering greater economic benefits for engineering projects.

Application
JIS SMA 400 AW are the best products for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneysand boilers.
The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.
Mainly used for construction of tanks, containers, bridges, frame structures, vehicles, etc with the request of welded, bolted, etc.
