RESEARCH ON THE MECHANICAL PROPERTIES OF 460 MEGAPASCALS FIRE-RESISTANT STEEL AT HIGH TEMPERATURE
【摘要】 在MTS809材料试验机上,完成了460 MPa耐火钢在温度为100~600℃,以及温度为600℃时不同保温时间的高温拉伸试验,并进行了试样断口微观形貌的分析。试验结果表明:460 MPa耐火钢600℃的屈服强度满足设计强度的要求。
【Abstract】 On MTS809 material test machine,the high temperature tensile tests of 460 MPa fire-resistant steel at 100-600 ℃ and 600 ℃ with different dwell times were completed,and the fracture morphology of the specimen was analyzed.The test results showed that: the yield strength of 460 MPa fire-resistant steel at 600℃ could meet the requirements of the design.
