S690QL high-strength steel is used for low temperature, high strength key components, construction machinery, mining machinery structure, etc. European standard high strength steel plate, S460M steel plates, manufacturing various types of construction machinery, such as mining and various types of construction drilling rig, electric shovel, electric wheel dump truck, mining truck, excavator, loader, bulldozer, various types of cranes, coal mine hydraulic supports and other structural parts.
The basic phases of S460M steel plates, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude S460M steel plates steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a S460M steel plates crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.
