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 9% -12% Cr creep-resistant cast steel. Describes the process of welding and heat treatment of the material, through the pre-welding preheating, welding current, welding speed control, etc., in the A3 temperature above 150 ℃ normalizing treatment, supplemented by appropriate tempering and de-stress treatment, produced by Castings to meet the technical standards.
