摘要
根据 Ａ Ｓ Ｍ Ｅ Ｃｏｄｅ 的要求，绘制了 Ｓ Ａ５０８－ ３ 钢的断裂韧性和疲劳特性曲线，表明国产钢的安全裕度较大，生产蒸发器时对母材、焊缝及热影响区都可按此方法测定。
SA508-3 steel characteristic curves of fracture toughness and fatigue strength are drawn according to ASME Code, the abundant safety margin of Chinese-made steel is indicated, the method also can be used on measuring materials 、welding seams and heat influence zones when manufacturing steam generator.
