Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, A514 grade Q alloy steel plate quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the A514 grade Q alloy steel plate International leading steel materials supplier.
The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of A514 grade Q alloy steel plate seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
S355J2 steel plate A514 grade Q alloy 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 A514 grade Q alloy steel plate 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℃.
