S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A709 grade 50 high strength steel, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
Perhaps this A709 grade 50 high strength steel explains why Trump has warmed to the idea of constructing a border wall on the U.S. border with Mexico out of steel rather than concrete. In an interview with NPR, Tom Gibson, president and CEO of the American Iron and Steel Institute estimated that the barrier would require a hefty order of A709 grade 50 high strength steel 3 million tons of steel.

The advantage of plasma cutting is that it can cut thin plates, stainless steel and non-ferrous metals, and the cutting speed is fast. The disadvantage of plasma cutting is that the incision will have a slope, and there will be noise when cutting. The advantages of water jet cutting are wide cutting range and environmental protection, but the disadvantages of water jet cutting are slow cutting speed and high energy consumption. Do you know what is the best cutting method for A709 grade 50 high strength steel?
