Q355NH Weather Resistant Steel Plate

Q355NH Weather Resistant Steel Plate Q355NH weather resistant steel plate is one kind of Chinese corten steel plate under the standard of  GB/T 4171, now the Q355NH have new garde name: Q345NQR2(09CuPCrNi-A), Q345NQR3(09CuPTiRE-B), Q345NQR4(08CuPVRE), Q350EWR1(S350E). Q355NH weathering steel plate has high tensile strength with 490-630 Mpa.What the Q355NH mean? "Q" means the abbreviation of Chinese Pinyin: “Qufu”, which means Yield Strength "355"  indicates the minimum yield strength 355 MPa for steel diameter or thickness ≤16mm "NH" denote the abbereviation of Chinese Pinyin: "Naihou", which means corten steel Product advantage:1. Thanks to it's good weldability and low temperature impact toughness, which helps it is suitable for architecture, artifacts such as weather resistance of weldments.2. Excellent impact strength.3. Good perfomance of corrosion resistance.4. As it's corrosion resistance, it can expand the life of use and save the cost of economy.5. I…
