Q355NH steel plate under China GB/T 4171 standard, it is a kind of weathering steel. Q355NH weathering steel plate is the high tensile strength weathering steel plate, it has 490-630 Mpa tensile strength. More information about Q355NH weathering steel technology, please see the following:GB/T 4171 Q355NH weathering steel - BEBON steelCompared with carbon steel, Q355NH steel has better corrosion resistance in the atmosphere. Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering resisting steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent.
