S690QL steel suppliers properties - chemical composition and mechanical property

S690QL steel suppliers, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.

S690QL steel suppliers controlled rolling is that, on the basis of adjusting the chemical composition of S690QL steel suppliers, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S690QL steel suppliers.

Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. S690QL steel suppliers, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.
