The generally spoken manganese plate is low alloy high strength structural steel. This material has good weldability and can be welded by various methods. Carbon steel plate and manganese plate belong to the category of carbon structure and low-alloy structural steel. The main difference between carbon steel plate and manganese plate is that the yield strength of manganese plate is higher than that of carbon steel plate, CCS D36 hull steel plates. From the point of view of hardness, it is obvious that the hardness of manganese plate is larger than that of carbon steel plate, and the application of manganese plate is relatively wider.
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate CCS D36 hull steel plates should also have good welding performance and low notch sensitivity.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized CCS D36 hull steel plates are higher than that of annealed CCS D36 hull steel plates, but the elimination of internal stress is not as good as annealing. The normalizing operation of CCS D36 hull steel plates is simple, the cost is low, the productivity is high, and it is widely used in actual production.
CCS D36 hull steel plates, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of CCS D36 hull steel plates and No. 20 steel is 7.85kg/cm3
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
