Chemical composition for PSL1 X65 seamless pipe with t≤25.0mm (0.984 in)

Remark: 

1) For each reduction of 0.01 % below the specified maximum concentration for carbon, an increase of 0.05 % above the specified maximum concentration for Mn is permissible, up to a maximum of 1.75 % for grades > L360 or X52, but < L485 or X70.

2) Unless otherwise agreed, Nb+V+Ti ≤ 0.15%.

Chemical composition for PSL2 X65 seamless pipe with t≤25.0 mm (0.984 in)

Remark:
