研究了热轧态Si-Mn双相钢的冲击韧度。试验结果表明,形变态螺栓的冲击韧度已基本符合GB3098.1-82的要求。经490℃回复90min后,冲击功达约120J,且拉断力符合GB3098.1-82的要求。对试验数据进行了计算机拟会。
The impact toughness of hot-rolled Si-Mn duplex steel was studied. The test results show that the impact toughness of deformed bolt has basically meet the requirements of GB3098.1-82. After the 490 ℃ response 90min, the impact power of about 120J, and breaking force GB3098.1-82 meet the requirements. The experimental data were simulated by computer.
