Comparison chart of grade S690QL structural

The hot rolling method is to heat the grade S690QL steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of grade S690QL rolling process is usually called semi-finished product production, also called blank production.

Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.

Although Q345E steel plate has stronger torsion resistance and better corrosion resistance than ordinary steel plate, there are still some environments that can cause corrosion to Q345E steel plate. The following environment should be avoided as far as possible to avoid corrosion of grade S690QL, Q345E steel plate. 1. Acid water. 2. Salt water. 3. Nitric acid. 4. Atmospheric erosion. Atmospheric erosion for Q345E steel plate corrosion is reflected in the chloride and pollutant pollution source of Q345E steel plate corrosion, this corrosion is very serious.

ArcelorMittal said it was taking measures to cut its North American grade S690QL steel production in response to the weakening demand for downstream steel after the outbreak of covid-19, foreign media reported. It is reported that ArcelorMittal's plant in the port of Indiana is ready to shut down the No. 4 blast furnace.
