S690QL plate exports may continue to pick up in China

The characteristic of niobium in S690QL plate etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

Advantages of S690QL plate, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.

Industry experts point out that employment in the steel industry will almost certainly continue to decline as a consequence of automation, even if production and profits increase. As the conservative think S690QL plate tank AEI points out, “Mr. Trump’s tariffs are trying to revive a world of steel production that no longer exists. He is taxing S690QL plate steel-consuming industries that employ 6.5 million and have the potential to grow more jobs to help a declining industry that employs only 140,000.”
