S275JR carbon steel material cold rolled coil

S275JR carbon steel material,When cutting extra thick S275JR carbon steel material steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.

Different form S275JR carbon steel material, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

S275JR carbon steel material,S355J2 steel plate 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 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℃.
