This document describes the specification of high manganese (Mn) austenitic steel plates to be used for LNG tanks on board ships. The specification of high manganese austenitic steel could be also considered for design and manufacture of cargo tanks and process pressure vessels of LNG supply/terminal and transportation of fuels and traded gases to comply with related requirements of IGC Code and/or IGF Code. This document will be primarily applicable for the specification of LNG tanks below volumetric capacity of approximately 30 000 m3 using high manganese austenitic steel. The thickness of plates is limited from 6 mm up to 40 mm and only by the capacity of the material to meet the specified mechanical property requirements.
