The important role of Q295NH weathering steel plate

The purpose of Q295NH weathering steel plate annealing is as follows:(1) reduce the hardness of Q295NH weathering steel plate, improve the plasticity, in order to facilitate cutting and cold deformation processing. (2) refine the grain, uniform the structure and composition of steel, improve the performance of Q295NH weathering steel plate or EStE 255 structural steel sheet strength parameters - DIN The main materials of weathering steel are:Q355GNH, 09CuPCrNiA, 05CuPCrNi, Q345NH, Q235NH, Q295NH, EStE 255 structural steel sheet, Q275NH, Q355NH weathering steel plate. Weathering steel plate products are widely used in outdoor, indoor decoration, twilight wall decoration and used to manufacture containers, railway vehicles, oil derricks
