Q345 steel (0.12%-0.20% C,0.20%-0.60% Si,1.20%-1.60% Mn,0.030% S,0.030% P, in mass%) was used to prepare the work electrode. The working electrode was embedded in epoxy resin within a PVC tube. The electric contact was obtained by soldering a copper wire on the back of the working electrode. The working surface had an area of 1.13 cm2. The Effects of metallic microstructures on fatigue fracture of Feb 11, 2020 · The experimental material as received is a 12-mm-thick hot-rolled high-strength low-alloy Q345 steel plate. The chemical compositions of Q345 plate were C 0.16, Si 0.35, Mn 1.34, S 0.011, P 0.022, and Fe balance (wt.%). The metallic microstructure was revealed by 4.5 vol.% Nital after mechanical polishing.
Carbon steel is a kind of metallic material that widely used in construction, machinery, manufacturing and other domains. In the mechanical structure system, long-term cyclic stress may cause the mechanical components failure. In this work, the characteristic of fatigue crack propagate in low carbon steel Q345 and the effect of loading frequency to the fatigue property of Q345 steel were Influence of hot rolling + heat treatment on Jan 03, 2021 · Therefore, a new type of wear-resistant steel composite plate is prepared by rolling composite method, which combines the wear resistance of NM500 steel and the toughness of Q345 carbon steel. The microstructure and properties of NM500/Q345/NM500 composite three-layer plates after hot rolling, quenching and tempering were studied in the work. Investigation of the Surface Integrity of Q345 Steel After Considering that Q345 steel has high strength and hardness, good wear resistance, and thermal conductivity, it is widely used in mining machinery parts. However, the working environment in the mining field is harsh, and the steel easily reacts electrochemically with oxygen to form rusty oxides, which greatly reduces the life and performance of
