The participation of microalloying elements can not only play a role in the marching strength, but also compensate for the loss of strength caused by the reduction of carbon equivalent, and the welding, mechanical and technological functions of the traveling steel. Because of the environmental requirements of the higher strength ship plate of CCSAH960 steel plate, it can meet the requirements of high strength, high toughness, high welding function, and thickness direction function.

CCSAH960 when taking impact test samples for steel with a thickness of 6mm~<12mm, small samples of 5mm*10mm*55mm and 7.5mm*10mm*55mm can be taken respectively, and the impact energy values are not less than 2/3 and 5/6 of the specified value respectively. <b118>
The impact test results of CCSAH960 steel are calculated based on the arithmetic mean of a set of 3 specimens, allowing 1 of the experimental values to be lower than the specified value, but not less than 70% of the specified value.

The section shrinkage rate of CCSAH960z in the direction of steel thickness should be in accordance with the provisions of Table 7. The arithmetic mean of the 3 specimens shall not be lower than the average value specified in Table 7, and only the single value of one of the specimens shall be lower than the average value specified in Table 7, but shall not be lower than the small single value of the corresponding steel grade in Table 7.
