Characteristics and application scope of A572 Gr 60 carbon steel plate sheet

Through chemical composition analysis and simulation tests, it is found that A514 Gr Q steel plate is prone to cracks or decreased toughness during welding. ASTM A514 Gr Q steel plate is sensitive to cold cracking. In order to obtain good weld quality of A572 Gr 60 carbon steel plate sheet, A514 Gr Q steel plate, it should be controlled from two aspects: (1) control the hardness value of HAZ; (2) control the residual diffusible hydrogen content.

In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the A572 Gr 60 carbon steel plate sheet construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU A572 Gr 60 carbon steel plate sheet steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.
