High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the A588 Grade B carbon steel, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
Myanmar's demand for A588 Grade B carbon steel steel products is likely to exceed 3 million tons in 2020 and 5 million tons by 2025, according to seaisi. However, Myanmar's producers are unable to meet domestic demand, so the country's steel products are more dependent on imports. In 2019, Myanmar imported more than 1.9 million tons of A588 Grade B carbon steel finished steel, including 57% of long products, 13% of uncoated hot-rolled and cold-rolled flat products, and 30% of coated steel. In order to reduce its dependence on imports, Myanmar plans to increase its steel production capacity by building and expanding steel mills.
The properties of A588 Grade B carbon steel ASTM A36 steel allow it to deform steadily when the stress increase exceeds the yield strength. This ductility enables the building to stand still after meeting the structural limit in an emergency. Other A588 Grade B carbon steel high-performance steel, such as bridge strand, has very strong strength and brittleness, and its deformation is minimum before severe fracture of bridge strand.
