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 steel A573 Grade 58 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 steel A573 Grade 58 steel industry.
Composition characteristics of steel A573 Grade 58 product: (1) Low carbon: Due to high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%. 2) Add manganese-based alloying elements. 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the steel.
Compared with steel A573 Grade 58, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of steel A573 Grade 58, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.
Chemical composition differences between the steel A573 Grade 58, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
