Welcome to BBN High Strength Steels Factory

Export S550 steel plate Pressure Vessel Plate

The company adopts the S550 steel plate international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S550 steel plate management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

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, S550 steel plate, 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.

Corrosion resistant steel prices are generally higher. What are the applications of S550 steel plate, corrosion resistant steel? First, the corrosion resistant steel can be used in chemical containers, such as furnaces. Some chemical products have strong corrosivity and need steel with excellent corrosion resistance, otherwise they will be easily corroded. Second, the corrosion resistant steel can be used for sewage pipelines. Industrial sewage pipelines need to discharge a large amount of wastewater, which may contain harmful substances.

S550 steel plate Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.

S550 steel plate, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
