摘要
根据新版DL/T 438-2016《火力发电厂金属技术监督规程》的相关规定,对T91/P91、T92/P92、T122/P122等9%~12%Cr钢母材及焊缝硬度(出厂硬度)指标进行调整,为保证产品硬度满足要求,采取统计过程控制(SPC),通过相应的工艺措施进行改善,使出厂硬度满足要求。
According to regulations of DL/T 438-2016Regulations for Supervision of Metal Technology in Thermal Power Plant,indicators of 9%-12%Cr steel metals,such as T91/P91,T92/P92and T122/P122,and weld hardness (delivery hardness)are adjusted to guarantee that product hardness can satisfy requirement.Statistical process control (SPC)are used,and relevant process measures are improved,then delivery hardness can satisfy requirement.
