P355QL2 is similar to what steel, P355QL2 steel plate fixed rolling, P355QL2 European standard quenc

P355QL2 is a European standard quenched and tempered container plate, P355QL2 steel plate application range

P355QL2 steel plate is alloy special steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance.

It is used to manufacture spherical storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil-welded containers, multi-layer hot-sleeved coil-welded containers, multi-layer wrapping containers and other second- and third-class containers and low-temperature pressure vessels.

P355QL2 steel plate fixed rolling: the grades in the Wugang Xiangyang

specifies a number of options, which are listed below. In addition, the relevant options of EN 10028-1:2017 apply. If the buyer does not express a wish to implement any of these options at the time of inquiry

and order, the product shall be supplied in accordance with the basic specifications (see also EN 10028-1:2017).

1) Provide data on suitable welding conditions (see 8.2.2);

2) Intermediate thickness specimens for impact tests (see Clause 10);

3) limits on copper and/or tin content (see Table 1, footnote c);

4) No choice, deliberately left blank;

5) a specification with a minimum impact energy of 401 (see 8.4 and Table 4, footnote a);

6) Applicability of QL grades (see Table 5, footnote a).
