Thermal processing of S355K2 carbon steel plate sheet steel sheet

As an important classification of steel, S355K2 carbon steel plate sheet hot rolled steel coil has the following advantages: first, hot rolled steel coil can be curled at will, reducing the occupied space, and it is convenient for transportation. Second, the processing of hot rolled steel coil is flexible and convenient. For spiral welded pipe, coil uncoiling, leveling, trimming, forming and welding are used. For longitudinal welded pipe, it must be formed and welded with steel plate. The hot rolled steel coil price is affected by the size and specification. The prices of different specifications and thickness S355K2 carbon steel plate sheet, hot rolled steel coils are different.

Q370qC, Q370qD, S355K2 carbon steel plate sheet and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the S355K2 carbon steel plate sheet plate should be derusted before cutting.
