The charpy impact values of p355gh steel usage

As an important classification of steel, P355GH steel usage 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 p355gh steel usage, hot rolled steel coils are different.

ASME p355gh steel usage delivery status: thickness ≤40, hot rolled or normalized; thickness ＞40, normalizedAccording to the different tensile strength of the material, ASME SA204 steel is divided into three strength grades: A, B, and C, namely SA204GrA, SA204GrB, and SA204GrC. The maximum thickness of steel plates corresponding to these three grades is limited to:SA-204A large plate thickness does not exceed 150mmSA-204B large plate thickness does not exceed 150mmSA-204C large plate thickness does not exceed 100mm

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the p355gh steel usage plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
