Abstract:Taken the engineering application realization of domestic low temperature steel as the goal, combined with the actual situation of the enterprise, the engineering application of domestic low temperature steel for 84 000 m3 Very Large Gas Carrier (VLGC) is studied in four sides of base material reinspection, cold working performance test, hot working test, and welding procedure test. The results show that the engineering application of domestic low temperature steel is feasible, and the project quality using the domestic low temperature steel in the leading ship of the company is stable and reliable. The research provides a practical basis for the batch application of domestic low temperature steel of following VLGC.
