The main component of shipbuilding use GL-D hull structural steel manganese plate is manganese, which is a relatively powerful element type, and plays a more important role in long-term development and continuous use. The main characteristics of manganese plates are high hardness and high strength. For general manganese plates, it is necessary to enhance the compressive capacity of manganese steel plates and various basic corrosion resistance capabilities. For common manganese plates, pay attention to use, choose good specifications and classifications, thus the use value of manganese plates will be better.
Specification range of available steel shipbuilding use GL-D hull structural steel: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates shipbuilding use GL-D hull structural steel can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < shipbuilding use GL-D hull structural steel 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 shipbuilding use GL-D hull structural steel product packaging.
