Abstract
PURPOSE: To manufacture stably a steel plate that has a high crack tip opening displacement at liquid nitrogen temperature by hot-rolling and cooling Ni-steel in a specified condition.
CONSTITUTION: A slab heated to 1,000W1,200°C is rolled at ≥20% cumulative rolling reduction, and hot-rolled at roll finishing temperature of 750W950°C. After completion of hot rolling, the steel plate is cooled to ≤350°C at a cooling rate of 1°C/sec. Then, the steel plate is heated at a temperature between Ac1WAc3 and cooled to room temperature at a cooling rate greater than air cooling, and tempered at a temperature lower than Ac1.
