Chemical composition of AS3678-WR350 steel plate

AS3678-WR350 steel plate is Australian low-alloy steel. AS3678 represents the Australian low-alloy standard AS-NZS 3678, WR represents atmospheric corrosion resistance, and 350 represents the minimum yield strength value.

AS3678-WR350 steel plate chemical composition - finished product analysis:
C≤0.14, Si: 0.15-0.75, Mn≤1.70, P≤0.160, S≤0.030, Cr: 0.35-1.05, Ni≤0.55, Cu: 0.15-0.50, Mo≤0.10, Al≤0.100, Ti≤0.040
Note: (1) AS3678-WR350 steel allows the use of modified sulfide steelmaking technology.
(2) The limit value applies to both acid-soluble aluminum and all aluminum.
(3) The carbon equivalent CE is calculated based on the actual smelted composition or finished product composition value, and is calculated according to the following formula: CE=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
(4) Ni+V≤0.030%
(5) V≤0.10%, Ni+V+Ti≤0.15%.
