The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, A514 grade R alloy steel plate, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
For the A514 grade R alloy steel plate 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 R alloy steel plate 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.
Mechanical properties of S355J2 plate: yield strength Rp0.2 ≥ 275MPa, tensile strength Rm: 450 - 600MPa, elongation A ≥ 18%, - 20℃ impact energy ≥ 47J, tensile section shrinkage Z ≥ 35% in thickness direction. The A514 grade R alloy steel plate, S355J2 steel plate has excellent internal quality, high density and stable performance. S355J2 structural steel is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields.
