Which material is A131 grade B steel wide flats equivalent grade in China

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as A131 grade B steel wide flats. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

Myanmar's demand for A131 grade B steel wide flats 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 A131 grade B steel wide flats 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 company's ESP thin gauge is down to 0.6mm. The thinner the thickness of the A131 grade B steel wide flats, hot rolled steel product, the more difficult it is to roll. The thickness will encounter increased load, severe vibration of the rolling mill, difficult shape control, and fluttering of the head during the downdraft. There are many problems such as difficulty in getting bite, which limit the thinnest size that can be rolled by hot rolling. At present, the thinnest gauge of conventional rolling line is 1.2mm, and the thinnest gauge of CSP production line is about 1.0mm. The successful rolling of 0.6mm hot rolled steel product is a milestone in hot rolled steel strip technology.
