Abstract (en)
[origin: EP3130687A1] This thick steel plate satisfies a prescribed chemical composition, and has a Di value of 2.5-5.0, a sol. N parameter of 20 ppm or less, and an Ni-Ti balance of 0.0024 × ([Ni] - 7.5) 2 + 0.010 - [Ti] or less, and furthermore has a crystal grain diameter of 4.0 µm or less after heating at 700°C × 5s and cooling from 700°C to 500°C in 19 s.
