The toughness of steel such as ASTM A573 Grade 70(A573 Gr 70) plate 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.
Our quality control department will do inspection for details of the steel materials ASTM A573 Grade 70(A573 Gr 70) plate before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
Q370qC, Q370qD, ASTM A573 Grade 70(A573 Gr 70) plate and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).
According to the latest statistics of alacero, the consumption of finished steel ASTM A573 Grade 70(A573 Gr 70) plate products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.
