| Abstract: | This paper introduces principles of P91 steel submerged welding wire compositions design. Welding process comparison tests between METRODE 9CrMoV-N, which is manufactured by Metrode Products Ltd., UK, and the newly developed KJS91 submerged welding wire, are conducted, and the compositions, impactive temper, tensile strength, metallographic structures and hardness of the welds are also measured. Test results show that KJS91 has high temper and strength, and meets AWS and BSEN requirements. |
