A709 grade 50 structural steel sheet, S690QL steel plate is a quenched and tempered high-strength steel plate. "S" means that its grade is European standard, and the corresponding Chinese standard is Q690E high-strength structural steel. S690QL steel plate is used in the manufacture of low temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc.S690QL steel plate executive standard: EN10025-6.
Global A709 grade 50 structural steel sheet crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global A709 grade 50 structural steel sheet crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
Ordinary medium and thick steel plate A709 grade 50 structural steel sheet 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.
