“…Owing to the anisotropy induced during the rolling process, the fracture behavior of steel plates displays pronounced directional differences. This disparity may result in steel plates being more susceptible to fracture in certain directions and less so in others [65]. However, regarding the anisotropy of mechanical properties, numerous studies have drawn differing conclusions, ranging from the assertion that crystal texture has no impact on toughness anisotropy to the identification of specific, larger orientations [66][67][68][69][70][71].…”

The desire to explore the natural resources and geopolitical patterns of the North and South Poles has significantly increased the interest of experts and researchers in the development and utilization of the polar regions. In this article, we comprehensively analyzed the current state of the development of polar low-temperature steel around the world. We highlighted the challenges that must be addressed in the ongoing development efforts and summarized the expected future trends in this field. The main theme of this article involves the challenges encountered in polar environments primarily caused by the low-temperature toughness and seawater corrosion of marine steel.

“…Therefore, materials with high fracture toughness-to-yield stress ratio ( K c σ YS ) are preferred. On the other hand, for larger pressure vessels, this might not be possible to achieve, leaving designers with the option to allow the crack to stably grow until it reaches full thickness depth, accepting some leakage to occur, a criterion known as LBB [1,4,5]. In this case, materials displacement (CTOD) method by deriving the materials' resistance curve.…”

Fracture toughness determination is crucial for the design phase of pressure vessels, and, although ASTM E1820 and ISO 12135 fracture toughness standards have existed for some time, some differences have been reported in the determination of this property. This study investigates the ductile fracture behavior of ASTM A516 Gr.70 pressure vessel steel and assesses the differences in estimating both standards. The steel’s tensile properties and initiation fracture toughness (JIC) were evaluated, taking into account the parallel and perpendicular orientations to the rolling direction. The results reveal the properties’ dependence on the rolling direction, mainly attributed to perlite banding. Additionally, as for the JIC determination, the differences were associated with the different blunting line slope estimations on each standard, reinforcing the necessity of a work-hardening-based blunting line for each material assessed.
