  Q345B:C≤0.20,Mn ≤1.70,Si≤0.50,P≤0.035,S≤0.035;

  Q345C:C≤0.20,Mn ≤1.70,Si≤0.50,P≤0.030,S≤0.030,Al≥0.015;

  Q345D:C≤0.18,Mn ≤1.70,Si≤0.50,P≤0.030,S≤0.025,Al≥0.015;

  Q345E:C≤0.18,Mn ≤1.70,Si≤0.50,P≤0.025,S≤0.020,Al≥0.015;

  Q345A、B、C、D、E均含Nb≤0.07,V≤0.15,Ti≤0.20,Cr≤0.30,N≤0.012,Mo≤0.10。

  20#、Q235B

  方管重量计算公式:4*壁厚*(边长-壁厚)*0.00785

  矩形管重量计算公式:(周长/3.14-壁厚)*壁厚*0.02466
