Abstract

Research in LNG fueled ships are actively underway in the world. Accordingly, various materials were widely used as materials for storage tanks for ultra-low temperatures, and high manganese steel for ultra-low temperature was recently developed. In this paper, the transient thermal and residual stress analysis of the welding of 9% nickel steel and high manganese steel are presented. 9% nickel steel tended to have higher transverse direction stress and longitudinal direction stress than high manganese steel.
