1.Introduction of JIS G***5 SPA-H steel plate

          JIS G***5 SPA-H isWeather steel plate, with alloy elements, such as Cu,Cr,Ni added, the anti-corrosion structural steel acquires a corrosion resistance ability and extends the service life,in the development and producing of anti-corrosion structural steel.

  It is a copper chromium alloy steel this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels.

 

2.Properties of JIS G***5 SPA-H steel plate

"NH"means that due to their chemical compositions, these steels exhibit increased resistance to atmospheric

corrosion compared to other steels. This is because the steel forms a protective layer on its surface under the influence 

of the weather.

The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration 

of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to 

the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating.

1.Introduction of ASTM A**8 Grade A

        ASTM A**8 Grade A resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions. The surface of the metal ASTM A**8 Grade A can form a coating of dark brown oxidation ,which inhibits deeper penetration, so A**8 Grade A steel save the cost of need for painting and costly rust-prevention maintenance over the years.

 Delivery Condition of A**8 Grade A can be Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP)
