What grade is a516 grade 70 steel for bridge construction?

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, a516 grade 70 steel for bridge construction quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the a516 grade 70 steel for bridge construction International leading steel materials supplier.

VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.

Special boiler steel is derived from carbon structural steel, a516 grade 70 steel for bridge construction. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the a516 grade 70 steel for bridge construction, stainless steel from corrosion.

The toughness of steel such as a516 grade 70 steel for bridge construction is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
