Identify 05CuPCrNi weathering steel plate and ordinary steel plate’s difference

1、 ① steel plate has no long rust stage, the naked eye can not distinguish the genuine 05CuPCrNi weathering steel plate and ordinary hot-rolled steel plate, 1, need to refer to the steel factory's warranty book, the warranty book requires the supplier to provide the original red steel stamp, so as to avoid the merchant Inferior filling. The common materials of the genuine 05CuPCrNi weathering steel plate are 09cupcrnia, B480GNQR, etc. of Baosteel or Anshan Iron and Steel, and the materials of ordinary hot-rolled steel plate are Q235B, SPHC and so on.

② Provide samples to professional third-party testing organizations to check whether the metal components match the warranty book [this method can be used at any stage of long rust]
