	> 6.0mm	≥ 335 MPa	≥ 490 MPa	≥ 15

SPA-A steel all made of carbon steel and copper, nickel, phosphorus and other chemical elements. The content of these chemical elements, only a few percent. Because different alloying elements, weather resisting steel has better mechanical properties, as well as greater corrosion resistance.

SPA-H steel Application:
JIS G3125 SPA-H steel widely used in air preheater, economizer, railway carriage, containers production, bridge building, construction and so on.
