本发明系关于一种抗延迟龟裂之呈现相变诱导塑性(TRIP)效应之不锈钢及该不锈钢之制造方法。该不锈钢之抗延迟龟裂性系藉由在介于100℃及700℃间之温度范围内进行0.1-300小时，较佳在200-600℃下进行1-100小时，及更佳在250-500℃下进行1-100小时之热处理将藉由惰性气体熔融方法测得之不锈钢的总氢含量限制为低于4重量ppm，较佳低于3重量ppm而达成。 The invention relates to a stainless steel exhibiting transformation-induced plasticity (TRIP) effect resistant to delayed cracking and to the method for producing the stainless steel. The resistance to delayed cracking in the stainless steel is achieved limiting the total hydrogen content of the stainless steel measured by inert gas fusion method below 4 weight ppm, preferably below 3 weight ppm by a heat treatment performed at the temperature range between 100℃ and 700℃ for 0.1-300 hours, preferably at 200-600℃ for 1-100 hours, and more preferably at 250-500℃ |
