What is the specific use of A514 grade E quenched and tempered steel, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
For the A514 grade E quenched and tempered steel construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that A514 grade E quenched and tempered steel steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.
Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the A514 grade E quenched and tempered steel, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.
ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of A588 and expand its application range. Firstly, the alloy composition increases the A514 grade E quenched and tempered steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, A588 A514 grade E quenched and tempered steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, A588 angle steel is widely used in bridge, building and other structural fields.
