摘要
GX12CrMoWVNbN10-1-1是一种新型9%-12%Cr抗蠕变铸钢。介绍该材料焊接及热处理的工艺,通过对焊前预热、焊接电流、焊接速度等的控制,在A3温度150℃以上进行正火处理后,辅以适当回火及去应力处理,所生产的铸件满足技术标准的要求。
GX12CrMoWVNbN10-1-1 is a new type of creep resistance steel with 9%-12% Cr. The welding and heat treatment process for the steel was introduced. Through the control of preheating, welding current and welding speed, and normalizing at above 150 ℃ of A_3 temperature, with appropriate tempering and stress relieving, the produced castings can meet the requirements of technical standard.
