In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A588 Gr B high strength steel high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A588 Gr B high strength steel technical equipment.

In February 2019, the European Union stated that the sharp increase in Turkish A588 Gr B high strength steel and so on steel imports has seriously threatened steel production enterprises in member states. The EU has set import quotas for 26 steel products and imposed a 25% tariff on steel products imported in the future for a period of three years. The Turkish Trade Ministry said on Friday that Turkey had initiated a lawsuit against the EU on steel import tariffs with the World Trade Organization (WTO).
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A588 Gr B high strength steel etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
