GBT4171 Q235NH weatherproof steel sheets are cost effective

GBT4171 Q235NH weatherproof steel sheets are rather cost effective and therefore widely used in the manufacture of steel structures such as vehicles, bridges, towers, containers and other steel structures, etc.

GBT4171 Q235NH weatherproof steel sheets have better atmosphere corrosion resistance than mild steel. And Q235NH weatherproof steel sheets price is cheaper than stainless steel price. That mainly because Q235NH steel contains only a few trace elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium and titanium. The total alloying elements in Q235NH weatherproof steel sheets are only a few percent, not as much as that of stainless steel.

GBT4171 Q235NH weatherproof steel sheets production process are generally as below: fining material into furnace-smelting - micro alloying- argon blowing - LF refining - low superheat continuous casting - control rolling – control cooling.
