A871 gr 60 weather resistant plate Usage：
A871 gr 60 weather resistant plate refers to a weathering steel rust resistance to atmospheric corrosion protection, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel. Compared with carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent, rather than as stainless steel, reached a hundred per dozen, so the price is relatively cheap.
