GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, A387 GR.5 CL.2 pressure vessel steel sheet, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut A387 GR.5 CL.2 pressure vessel steel sheet, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.

A387 GR.5 CL.2 pressure vessel steel sheet, Q690 steel is low alloy high strength steel. It belongs to the Chinese GB standard steel. Q690 steel is named after its yield strength value. Q is the abbreviation of yield strength, that is, the yield strength of Q690 steel is 690 MPa. Chemical composition of Q690 steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 1.00, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. The mechanical properties of Q690 steel are: yield strength ≥ 690 MPa, tensile strength 730-940 MPa, elongation after fracture ≥ 14%, impact energy 31J.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
