S420NL-Z35 steel plate is alloy structural steel, and it implements the European standard EN 10025-3. The chemical composition of S420NL-Z35 steel plate: C:≤0.2, Si:≤0.6, Mn: 1 - 1.7, P:≤0.025, S:≤0.02. Delivery state of A514 grade Q alloy steel plate, S420NL-Z35 steel plate: quenching + tempering. Of course, the delivery status can also be selected according to specific demands. However, it needs to be communicated between the supplier and the demander and indicated in the contract.
In 2019, A514 grade Q alloy steel plate, crude steel production in North America was 120 million tons, down 0.8% year-on-year, among which crude steel production in the United States in 2019 was 87.9 million tons, up 1.5% year-on-year. The crude steel output of the CIS countries in 2019 was 100.4 million tons, down 0.5% year on year.
Ordinary medium and thick steel plate A514 grade Q alloy steel plate is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.
