Compare these impact results for each metal to tabulated values from a source such as the ASM Metals Handbook. Comment on .results from the Charpy impact test of the Titanic hull steel for the longitudinal and transverse rolling directions with a modern ASTM A36 mild steel [7]. Unfortunately for the purposes of a direct correlation of properties and microstructure, the comparison of mechanical behavior was
An exhaustive search through the literature of several authors was performed to collect experimental CVN data about wet welding being applied to A36 steel for comparison with CVN data obtained in this study. By using Charpy impact energy (CVN), KIC values could be predicted by KIC-CVN correlations.The results revealed that CVN values are proportionate to K IC, this data decreases as . Although this CVN impact test data does not represent the real fracture toughness . Fracture Toughness and Charpy CVN Data for A36 Steel with Wet Welding Soldagem & Inspeção. 2017;22(3):258-268 261The Charpy impact test is carried out in a 3-point flexure setup.The Charpy specimen is centered on the supports in the pendulum impact tester and rests against two anvils. In the case of notched specimens, the notch faces away from the pendulum hammer and is placed exactly across from the point at which the hammer strikes the specimen.
completed impact tensile testing results at -20oF conditions for dual-marked 304/304L and 316/316L stainless steel material specimens (hereafter referred to as 304L and 316L, respectively). Recently completed welded material impact testing at -20 oF, room, 300 oF, and 600 oF is also reported. Utilizing a drop-weight impact test machine and 1/4 .In addition, a search of Charpy CVN values using A36 steel and E6013 electrodes was performed with wet welding. Finally, K IC -CVN correlations were presented to measure the fracture toughness. As conclusions they drawn that CVN impact energy and K IC values decrease as the sea depth increases. Yes, to your second question. The cold rolled will have slightly lower notch toughness, provided both steel plates were provided in the same heat treatment condition (hot rolled, air cooled). The problem with A36 with regards to impact properties is variability in impact values based on plate thickness, and steel making practice.
