S355G10 + M steel plate is for marine engineering. "S" indicates structural steel, "355" indicates minimum yield strength of steel plate, and "G10" indicates mechanical function test that imitates post-weld heat treatment. "M" indicates control rolling. S355G10 + M plate is structural steel for marine engineering and belongs to European standard high-strength structural steel. S355G10 + M steel plate has good mechanical function, welding function and technological function.
Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some GL-EH 40 higher strength steel, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.
The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the GL-EH 40 higher strength steel, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
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 GL-EH 40 higher strength 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.
