| Abstract: | The change in property is studied after the normulised steel plate grade SAS16 Gr. 70 going through different time of post-weld heat treatment and the masons of it has been analysed in this paper. The result shows that the strength,plasticity and toughness of steel decrease with the number of simulated weld heat treatment increasing, especially the first time simulated post-weld heat treatment. |
