Results of mechanical testing A steel rolled plate in the grade F40SW, 40 mm in thickness, was subjected to TKDS test. Table below gives a summary of the results. So for the metal of this plate TKDS temperature comes to -45°C. Temperature, °C Average ductile portion, % Average load drop, % -20 100 0 -30 90 13 -40 86 15 -50 70 40 -60 62 59 -90 21 97
