In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A588 Gr B high strength steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A588 Gr B high strength steel supplier in the world.
With the rapid development of economy, there are many kinds of engineering projects, and their development is very fast. However, steel is an essential material in construction engineering. At present, there are many kinds of steel products on the market. In order to ensure the construction quality, the requirements for the strength, quality and corrosion resistance of A588 Gr B high strength steel, steel are more and more strict.
A588 Gr B high strength steel and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of A588 Gr B high strength steel and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
The ability to resist plastic deformation and fracture under the action of external load is called A588 Gr B high strength steel strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.
A588 Gr B high strength steel, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.
