摘要
针对南钢开发的EH47-BCA止裂钢,采用梯温型双重拉伸试验测量钢板-10℃止裂性能（Kca）为7896 N/mm^3/2,止裂温度、止裂韧性测试稳定性好、工程运用适用性好。满足各国船级社提出的技术指标值（-10℃的止裂韧性Kca≥6000 N/mm^3/2）。
EH47 crack arrest steel developed by NISCO, temperature gradient type double tensile test was done to get -10℃ crack arrest property （KCa） 7896 N/mm^3/2, crack arrest temperature, measuring stability of crack arrest toughness and engineering application are good to up to the technical index which classification societies proposed （ - 10℃ crack arrest properties of Kea ≥6000 N/mm^3/2）.
