For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In A514 grade Q QT steel plate, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
By Region: data shows that in the first quarter of Asia, crude steel A514 grade Q QT steel plate production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.
Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.
How much is the price of A514 grade Q QT steel plate, medium and heavy plate? First of all, there are many kinds of medium and heavy plate specifications, and the prices of different specifications are also different. Secondly, there are many kinds of medium and heavy steel plate materials. Different materials / steel grades have different uses, and the price will also change. Thirdly, we should also look at the manufacturers of steel products and pay attention to the steel grades of different manufacturers, so as to avoid buying poor quality medium and heavy steel plates.
