Low alloy high strength structural steel is a kind of steel which contains a small amount of alloy elements and is mainly used in construction and engineering structures. Main Chinese steel grades of low alloy high strength structural steel are: Q345A, Q345B, Q345C, Q345D, Q345E, Q390A, Q390B, Q390C, Q390D, Q390E, Q420A, Q420B, Q420C, Q420D, Q420E, Q460C, Q460E, Q500C, Q500D, Q500E, Q550C, Q550D, Q500D, Q620E, Q690C, Q690E, P355GH steel density.

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 p355gh steel density, 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.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. p355gh steel density, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.
