These grades A709 Grade 36, A588 Grade K GB equivalent, A709 Grade 50 and A709 Grade 50W are often specified with Charpy tests referencing the specific zone or lowest anticipated service temperature. The Charpy tests are specified as non-fracture critical, which is a per-heat test (frequency "H"), or fracture critical, which is a per-plate test (Frequency "P"). Bridge steels can be ordered with plate thickness up to 150mm.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < A588 Grade K GB equivalent steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished A588 Grade K GB equivalent product packaging.

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.
