We have 4 typical production lines A709 grade 50W structural steel sheet, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
For the A709 grade 50W structural steel sheet construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that A709 grade 50W structural steel sheet 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.
Q960 quenched and tempered steel executive standard: GB / T 16270. Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. A709 grade 50W structural steel sheet, Q960 quenched and tempered steel has high yield strength and tensile strength, and has great resistance to brittle failure. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welding structures and low temperature environment.
