What are the latest steel plate specification grade S690QL prices

The company has allocated special environmental protection facilities for all steel plate specification grade S690QL pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel plate specification grade S690QL steel mill scale, environmental protection dust has reached 100%.

High strength steel is a kind of steel often used in engineering construction. With the improvement of technical level, the research and development of high strength steel in China has made remarkable achievements. The application of high strength steel steel plate specification grade S690QL in the construction field can reduce the steel consumption and building volume, and improve the building weight. That is one of the important reason why the high strength steel is so warmly welcomed nowadays.

The requirements for toughness impact energy of steel plate specification grade S690QL, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
