S355J2 steel plate A514 Gr Q structural steel material rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the A514 Gr Q structural steel material single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
45# steel is high-quality carbon structural steel with low hardness and easy cutting. After quenching and tempering, the parts have good comprehensive mechanical properties. 45# steel is widely used in motorcycles and automobiles, especially those connecting rods, bolts, gears and shafts that work under alternating loads, huge friction, usually quenching method to improve its own hardness, wear resistance and service life.
We can process the steel materials according to your drawing. Or if you can not make drawing, please send us A514 Gr Q structural steel material specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.
