The Q345B carbon steel plate sheet BBN steel surface heat treatment

AS3678 belongs to Australian carbon structural steel, AS is Australian number, 3678 stands for carbon structural steel. AS3678 executive standard: AS / NZS, prefixed with WR, indicates that it is better than that of low alloy steel grade in atmospheric corrosion resistance. For example: AS / NZS3678-250 AS / NZS 3678-WR350, where AS / NZS 3678 = the standard number, 250 / 350 = the minimum yield strength of steel, WR = atmospheric corrosion resistance. Q345B carbon steel plate sheet, AS3678-350 is a kind of structural carbon steel plate, which is mainly used in buildings requiring low and medium strength carbon steel plates, such as floor and bridge buildings.
