Despite the strong performance of the US economy, US ASTM A302 Grade B steel plate demand is still struggling to resume growth as the US dollar is strong and the manufacturing industry is hit hard, and shale oil and gas investment has fallen sharply. Due to structural problems, Japanese ASTM A302 Grade B steel plate demand is also facing a weakening trend, and it is also adversely affected by the appreciation of the yen after the Brexit referendum. The World Steel Association estimates that demand forASTM A302 Grade B steel plate in developed economies will increase by 0.2% year-on-year in 2018
