... to liquid hydrogen tanks, the size increase is limited. If the steel yield stress is approximately 200 MPa, the plate thickness must be increased when increasing the tank size, which ultimately increases the tank weight and production cost. To address these issues, an austenitic high-Mn stainless steel...

... ABSTRACT The increasing size of container vessels is accompanied by an increase of plate thicknesses as well as the extensive use of higher tensile strength steels. For large plate thicknesses as well as high yield strengths, the influence of these parameters on fatigue strength of thermal cut...

... opened hatch in upper deck. Integrity against brittle fracture must be more considered in extremely thick steel plate because fracture toughness against brittle fracture initiation generally decreases with an increase of plate thickness (thickness effect).

... of 7% nickel steel is composed of fine and homogeneous tempered martensite, necessary and favourable to obtain a good level of strength, toughness, crack arrest properties and weldability. The grain size is about 16µm and is identical through the 7% nickel steel plate thickness. All plates present...
