Features of Q355GNH weathering steel

·Good corrosion resistance: Q355GNH 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, Q355GNH weathering steel also has certain chemical corrosion resistance.

·Good heat resistance: Q355GNH 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: Q355GNH weathering steel can resist oxidation and maintain brightness at room temperature, and has excellent aesthetic performance.

·Good toughness: Q355GNH 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, Q355GNH weathering steel has good corrosion resistance, heat resistance and oxidation resistance, as well as good toughness and aesthetics.
