Advantages of SPA-C steel

·Good corrosion resistance: SPA-C steel contains more copper, chromium, nickel and other alloying elements, which can form a dense passivation layer to prevent oxidation corrosion and strong atmospheric corrosion. At the same time, SPA-C weathering steel also has certain chemical corrosion resistance.

·Good heat resistance: SPA-C weathering steel can maintain a certain strength and toughness under high temperature environment, and its material also has good heat resistance after quenching and tempering.

·Good oxidation resistance: SPA-C weathering steel can resist oxidation and maintain brightness at room temperature, and has excellent aesthetic performance.

·Good toughness: SPA-C steel contains more manganese and other alloying elements, which can improve the toughness and wear resistance of the material while maintaining appropriate hardness.

In summary, SPA-C weathering steel has good corrosion resistance, heat resistance and oxidation resistance, as well as good toughness and aesthetics.
