SA516Gr70 steelmaking process: the steel should be killed steel and meet the requirements of A20 / A20M standard fine austenite grain size. Related steel grades are: SA515GR60, SA515GR70, SA516GR60, SA516GR70, SA516GR60N, SA516GR70N, elongation of P265GH.Chemical composition analysis of SA516Gr70: C: no more than 0.3, Mn: 0.79-1.30, P: no more than 0.035, S: no more than 0.035, Si: 0.13-0.45.

As the thickness and hardness of elongation of p265gh increase, the tendency to crack at the cutting edge increases. In order to prevent the elongation of p265gh from cutting cracks, preheating should be carried out before elongation of p265gh cutting. Special attention should be paid to preheating to make the entire elongation of p265gh interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole elongation of p265gh cannot be preheated, the partial preheating method can be used instead.
