The FS weldments were evaluated by performing transverse tensile and bend tests; hardness, Charpy V-notch toughness, and salt spray corrosion testing; and metallographic evaluations. The weldments exhibited satisfactory transverse weld tensile strength, ductility, Charpy V-notch toughness, and hardness....
HSLA 100 steel boasts a higher strength, lower weight, and good machinability and ductility compared to conventional mild carbon steel grades.
and 0.3wt.% Mo that provide weld metals characterized by an A r3 of 690°C, a CEN of 0.29, and a (B F M S ) of 30°C are expected to consistently overmatch the minimum specified tensile strength of HSLA-65 steel while offering a minimum CVN impact toughness of 41J at 40°C (30...

The tensile and impact tests indicate that enhanced cryogenic toughness combined with high strength and ductility of the steel plate can be achieved by introducing lamellarization treatment. 3.2. Microstructures of the AQ, QL, QT and QLT heat-treated specimens Fig. 3 shows the microstructural ...
Effects of Mo addition on microstructures and crack tip opening displacement (CTOD) in heat affected zones (HAZs) of three high-strength low-alloy (HSLA) steels were investigated in this study, and the correlation between them was explained by fracture mechanisms related with martensite-austenite ...
