“…It had been reported that welding high-Mn steel using nickel-based weld consumables (matched 9Ni steel) worsened cryogenic impact toughness at the coarse grain heat-affected zone (CGHAZ) [ 23 ]. This was confirmed to attribute mainly to the difference of chemical composition between the weld metal and the base metal, which led to the twinning difficulty and the lower plastic deformation capacity [ 24 ]. Meanwhile, the hardened austenite developed a high defect density, hindered the dislocation migration, and finally worsened the cryogenic impact toughness in CGHAZ [ 23 ].…”

“…With respect to SMAW of high-Mn steel, J.K. Ren [ 23 ] and X.Y. Fan [ 24 ] provided the mechanical properties of dissimilar welded joints using the Ni-based welding electrode, due to the lack of high-Mn steel welding electrodes, which have met the requirement of IMO. However, the high price of Ni-based welding consumables has also become a problem during the construction of LNG storage tanks.…”

“…For the SAW of high-Mn steel, X.Y. Fan [ 24 ] also investigated the SAW welded joint with Ni-based welding consumables. The tensile strength and elongation of dissimilar welded joints at room temperature was 713 MPa and 24%, respectively, while the impact absorbed energy of WM, fusion line (FL), and HAZ at −196 °C was only 9 J, 32 J, and 15 J, respectively.…”

The novel high-Mn austenitic steel is becoming a promising steel for cryogenic applications of LNG tanks. The welded joints take a critical role in cryogenic service for storage tanks. In this work, we developed well-matched high-Mn welding consumables and prepared the welded joints by shielded metal arc welding (SMAW), submerged arc welding (SAW) and gas tungsten arc welding (GTAW). The detailed welding parameters were proposed first, then the welding quality, mechanical properties, and microstructure were investigated. The results show that good welding quality, excellent mechanical properties, and stable levels of mechanical properties were obtained for high-Mn steel welded joints using similar welding consumables, the solid core of electrodes, and solid welding wires. Notably, the lowest cryogenic absorbed energy was found at 5 mm away from the fusion line rather than at the fusion line. The hardness of the welded joints was detected to be less than 280 HV due to the whole austenitic microstructure.

“…The four prevailing standards require high-manganese austenitic low-temperature steel plates to be delivered using the hot-rolling followed by the controlled-cooling process. Moreover, a number of researchers have delved into the effects of the various heat treatments [28,[72][73][74][75] and welding procedures [76][77][78] on the intrinsic characteristics of this steel variety. While various processing techniques have been employed by different scholars in their experiments, this treatise shall principally concentrate on unraveling the intricate interplay between the alloy composition and the performance attributes of high-manganese austenitic steel tailored for low-temperature environments.…”

High-manganese austenitic steel represents an innovative variety of low-temperature steel used in the construction of liquefied natural gas (LNG) storage tanks. This steel boasts remarkable characteristics such as exceptional plasticity, superior toughness at cryogenic temperatures, and robust fatigue resistance, all while providing significant cost benefits. By utilizing high-manganese steel, the material manufacturing costs can be considerably lowered, simultaneously ensuring the long-term stability and safety of LNG storage tanks. The alloying design is pivotal in attaining superior performance in high-manganese steel. Choosing the right chemical components to control the stacked fault energy (SFE) of high-manganese steel and fine-tuning its structure can further improve the balance between strength and plasticity. Summarizing the advancements in alloying design for high-manganese steel is of great importance, as it offers a foundational dataset for correlating the chemical composition with the performance. Therefore, this paper outlines the deformation mechanisms and the principles of low-temperature brittleness in high-manganese austenitic steel, and from this foundation, it explicates the precise functions of alloying elements within it. This aims to provide a reference for future alloying designs and the industrial deployment of high-manganese steel in LNG storage tanks.

Abrasion easily occurs due to the characteristic of the usage environment such as oil sands and construction equipment, and the demand for a steel with excellent wear resistance is increasing in various industries where specific parts are frequently replaced. Recently, by controlling the amount of manganese, high manganese austenite steels with improved wear resistance and low temperature brittleness performance have been developed and widely applied to LNG fuel tanks of ships and pipes. In this study, the temperature distribution, residual stress, and weld deformation caused by welding generated by friction stir welding(FSW) and submerged arc welding(SAW) for high manganese austenite steel with strong wear resistance were analyzed through thermal elastic plastic analysis.
