S690QL chemical composition price is moderate

Q345B material is a low-carbon alloy steel (c <0.20%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa. It has good comprehensive mechanical properties and technological performance. In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness.

The company is a leading company that sells S690QL chemical composition steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold S690QL chemical composition steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

How to distinguish between hot rolled and cold rolled process?
The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, S690QL chemical composition, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's S690QL chemical composition stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's S690QL chemical composition stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
