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 Material Properties of S355 Steel - An OverviewAug 23, 2015 · S355 Yield Strength. S355 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections. Here is the table showing reduction in yield strength based on thickness. Up to 16 mm - 355 Mpa. 16 mm < t 40 mm - 345 Mpa.

Q235,Q345,SS400 Grade Steel Plate Hot Rolled Steel Plate

Q235,Q345,SS400 Grade Steel Plate Hot Rolled Steel Plate Thickness 6-120mm. Description:Hot Rolled Steel Plate is made of low carbon steel that is commonly found in most industries. Hot rolled sheets are produced at elevated temperatures on rolling mills and generates a material that is resistant to work hardening and exhibits reduced levels of deformation residual stress.

Study on the Deep Penetration TIG Welding of Q345 Steel

The hardness of fusion zone is increased by 50% than that of base metal. This indicated that the one-side welding with double-sided shaping of 8 mm thickness Q345 steel can be realized by the deep chromium carbide overlay pipe chromium carbide overlay Chromium Carbide Overlay pipe is a wear pipe made of seamless steel base pipe onto which chromium carbide overlay is welded with an open arc process. We use an oscillating table with one welding head to arc weld the chromium carbide to the internal of the pipe.Q345 Chemical composition, Q345 Properties - Steel gradesBrinell hardness (HBW) 952 () 981 () 33:22:41:Solution and Aging, Annealing, Ausaging, Q+T,etc:222:Physical Properties of steel grade Q345.
