Research on Supervision and Control Measures for Low Hardness Parts of P91 Steel
A tracking test was conducted on the hardness,metallography,and wall thickness of low hardness P91 steel components caused by abnormal aging of a certain power plant.Through safety evaluation,more economical and convenient treatment measures were proposed for this type of component.It is believed that low hardness P91 steel components cannot be simply replaced,and the reasons for low hardness should be analyzed and classified to ensure that the hardness components of P91 steel meet the standards.
