In the world, 9Ni steel with the relatively low price, high strength, low temperature toughness and safety reliability has become the principal material of LNG storage tanks. The presence of coarse-grained microstructures in the weld microstructure has a substantial impact on the ultrasonic testing of the weld. Therefore, an excellent 9Ni steel ultrasonic testing technology is realized for a suitable welding process.
