GB/T 4171 Q310GNH Weather Resistant Steel Plate
Q310GNH weathering steel has good weather resistance and can resist atmospheric corrosion and some chemical media. It also has high strength and good weldability, and is suitable for the manufacture of structural components that require weathering performance.
Q310GNH weathering steel plate has a rust protection layer that is resistant to atmospheric corrosion, GB/T 4171 Q310GNH weathering steel plate can be used to manufacture vehicles, bridges, towers, containers and other steel low alloy structural steel.
Compared with carbon steel, Q310GNH steel has better corrosion resistance in the atmosphere. Compared with stainless steel, the alloying elements are only trace amounts of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and other alloying elements of total phosphorus, copper, chromium, vanadium, titanium and other alloying elements account for only a few percent.
