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.
As an important classification of steel, A514 grade E structural steel material 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 A514 grade E structural steel material, hot rolled steel coils are different.

Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A514 grade E structural steel material, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
