EIS of Q235 steel with epoxy coal tar coating was determined. It is shown that the infiltrative electrolyte amount into coating decreases with increasing coating thickness.
With electron microscope the fracture surface and metallographic structure analysis is done for typical sample of Q235, Q345 plate of low elongation, its reason found out, some Suggestions proposed.
Preparation of Nano-Grained Q235 Steel Plates and Their Microstucture and Mechanical Properties;
Roof purline is adopted with cold-bending and thin-wall steel (Q345), knee bracing, roof horizontal bracing and purline drawn rod Q235.
研究結果表明Q235鋼用J420焊條焊接後，焊縫的組織特點決定了其耐蝕*較差。
The microstructure and tensile fracture surface of the Q235 steel has been investigated by TEM and SEM.
整機機架，*鋼、槽鋼、厚壁方管、厚壁鋼板、牆板等就採用優質Q235-A鋼材。
利用無針攪拌頭，對C71000銅鎳合金和Q235低碳鋼進行了攪拌摩擦搭接焊。
Simulation of Q235 Steel Recrystallized Microstructure during Hot Forming Process;
結果表明，雙季銨鹽化合物MDOPD在模擬油田水介質中對Q235鋼具有非常顯著的緩蝕效果； 其緩蝕吸附膜隨吸附時間的延長而更加完整和緻密；
Galvanized steel grating: materials for Q235 or 304 stainless steel round bar, square steel, square steel twisted.
對梅山公司Q235冷彎不合格試樣進行了金相組織、冷彎斷口形貌及能譜分析。
The machine frame, beams, channels, thick wall square tube, thick wall plates, wall plate is USES the high quality of Q235-A steel.
