摘要:
针对国内某制管厂在对管材进行拉伸试验时屈服强度普遍偏高问题进行了深入调查分析,结果显示:试验机系统误差是拉伸屈服强度和抗拉强度偏高的原因之一;此外,误把规定非比例延伸强度R p0.5视为管线钢屈服强度R t 0.5,是屈服强度普遍升高的主要原因。
Abstract:
Through investigation and analysis into a pipe manufacturer in China,there existed a little higher in yield strength values at larger.The test results showed the system error of the test machine was one of the main reasons which led to the higher tensile and yield results.Besides,the other reason was the test system mistake the stipulated non-proportional extension strength R p0.5 as pipeline steel yield strength Rt0.5.
