Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as a36 ss400 asme low alloy steel. 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.
As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of a36 ss400 asme low alloy steel, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young's Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
The overall intention of supporting prices in the raw material market is relatively strong, but the steel mills have a low acceptance of high prices, and some just need a small amount of goods, so the overall market game state is obvious. With the poor release of steel demand, terminal merchants tend to consume low-cost inventory in the early stage and purchase on demand to avoid the risk of large-scale hoarding. However, the cost side is weak, and some a36 ss400 asme low alloy steel manufacturers secretly reduce prices to promote transactions. It is expected that the a36 ss400 asme low alloy steel market will be stable and weak in the future.
