The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, A514 Gr E QT steel plate. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
EN10025-2 S235J2 steel is equivalent to our Chinese teel grade Q235D. They are both done low temperature impact test at -20℃. Sometimes S235J2 would be used to built containers which can bear low temperature sea water. A514 Gr E QT steel plate, S235J2+N steel plate, following a rolling process within a certain temperature range, producing a material in a condition equivalent to that obtained after normalization. With the result that the specified mechanical properties values are conserved even after normalization treatment.
It is understood that resources in some markets have arrived normally recently and the overall A514 Gr E QT steel plate inventory has begun to increase, but the overall inventory pressure of A514 Gr E QT steel plate traders is still not large; secondly, the ex-factory prices of steel mills are firm, and A514 Gr E QT steel plate agents are low in willingness to trade at low price under the support of high costs. On the whole, demand has not improved overall, but ordering costs are high and inventory pressure is controllable. It is expected that the A514 Gr E QT steel plate prices may consolidate tomorrow.
