2.25Cr -1Mo -0.25V 钢焊接材料的再热裂纹敏感性试验方法探讨OACSTPCD
Test Procedure for Reheat Cracking Susceptibility of Welding Material Used to 2.25Cr -1Mo -0.25V Steels
在再热裂纹 Gleeble 试验的基础上,提出一种采用高温拉伸试验机对2.25Cr -1Mo -0.25V钢焊接材料进行再热裂纹敏感性测试的方法。采用该方法测得的断面收缩率(ROA 值)大于Gleeble 的试验结果。用其他低合金钢板作为试板时,若坡口面未堆焊2.25Cr -1Mo -0.25V 过渡层,则依据该方法制作的试样杂质元素含量相对较高,试验得到的 ROA 值较低。
Based on Gleeble test procedure,an acceptable screening test for reheat cracking susceptibility of 2.25Cr -1Mo -0.25V weld metal and flux was developed.The test machine is a simplified tensile ma-chine.The ROA value measured by this procedure is higher then by Gleeble test.If the welded couple is made by other low alloy steels,the bevel area have buttered with 2.25Cr -1Mo -0.25V weld metal shall got higher ROA value then the one not buttered,and the content …查看全部>>
