A514 Gr R alloy steel plate 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 A514 Gr R alloy steel plate 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.
This is the second year we have been golden supplier on Alibaba. Over the decades, we have accumunited rich customer resources and have established stable copperation with many customers all over the world. So we did not reply on A514 Gr R alloy steel plate B2B platforms. But with the development of the company and the increasing of the company reputation, it is necessery for us to open up more channels for customers to reach us.
A514 Gr R alloy steel plate controlled rolling is that, on the basis of adjusting the chemical composition of A514 Gr R alloy steel plate, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of A514 Gr R alloy steel plate.
At present, SN490 steel is mainly used in building structures, factories, stations and other buildings. Because of the high demand for safety, A514 Gr R alloy steel plate, SN490 steel will be restricted in some advanced countries. The upper and lower limits of yield strength can control the variability of steel yield strength.
