摘要
本文针对A204GrA 钢氢腐蚀事例的增多, 试验研究了不锈钢堆焊层对A204GrA 钢抗高温氢腐蚀的作用, 研究结果表明: 不锈钢堆焊层使Nelson 曲线中的A204GrA 曲线升高, 相当于提高了A204GrA 钢的高温抗氢蚀能力。利用以上试验结果, 分析了一台位于Nelson 曲线中不安全区的A204GrA 钢加氢反应器,表明在不锈钢堆焊层的作用下,
This paper aim at the more and more hydrogen attack for A204GrA steel,it is tested and studied that the effect of stainless steel weld overlay (SSWO) elevate the ability of hydrogen attack resistance of A204GrA.SSWO Let the Curve of A204GrA to elevate in Nelson Curve.Using above Test Results,A204GrA hydrogenator with austenitic stainless steel overlay was assessed.This hydrogenator can be safely used above 0 5Mo steel operating limit in Nelson Curve and will not be hydrogen attack during the period of inspection.
