Why S550QL steel quality is so important

Cold rolling steel is made of hot rolled coil under recrystallization temperature at room temperature. Cold rolled steel sheet is produced by cold rolling process, which is called cold plate. The thickness of S550QL steel, cold rolled sheet is generally between 0.1 mm and 8.0 mm. The thickness and width of cold rolled sheet produced by most factories are less than 4.5 mm. The thickness and width of cold rolled sheet are determined according to the equipment capacity of each factory and market demand.

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the S550QL steel hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S550QL steel steel industry.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S550QL steel steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

Oxygen is a harmful element in S550QL steel steel. With the increase of oxygen content, the strength of S550QL steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S550QL steel steel.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S550QL steel products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
