215mm thick, Quenching and Tempering, high tensile steel A514GrQ was produced successfully in
group Wugang Corporation
Recently, underwent the strict field inspection, Wugang researches and develops the production the
215mm thick ocean platform with quenching and tempering high tensile steel A514GrQ, authenticates
smoothly through the ABS classification society. Before this, Wugang independent research and development's
150mm, 185mm and so on different thickness specification's this aluminum obtains completely successful
and obtains the ABS classification society to authenticate. This symbolizes that Wugang has been able to
produce the ocean platform with all specification excel in aluminum, our country ocean platform realizes the manufacture domestically completely with the series high tensile steel. Wugang becomes domestic can
produce this aluminum completely independently only the Iron and steel enterprise. It is reported that the
overseas similar enterprise can produce this aluminum greatest thickness at present is 210mm.
Ocean platform (including production platform and oil drilling platform), because must undergo
natural forces and so on ocean waves, seaquake, low temperature corrosion and the destruction, is extremely
high to the steel each technical specification request, its essential spot like rack, the spud leg urgently need
the steel technical standard to be harsher. Its resilience needs to examine the steel plate thickness 1/2,
ordinary quenching is unable to guarantee radically regarding this. In order to realize the ocean platform
with the steel manufacture domestically, Wugang starts in 2008 to research and develop 140mm thick
quenching and tempering high tensile steel A514GrQ, the lasted 10 months obtain successfully, broke our
country ocean platform essential spot to rely on the import for a long time with the high tensile steel the
history. While 140mm thick A514GrQ realizes volume production, Wugang is also rapid invests a greater
thickness this aluminum research and development work.
A514GrQ production's biggest difficult problem lies, increases along with thickness, each target request
does not reduce. Wugang displays " the big scientific research fully " the pattern formidable superiority,
the science and technology, the production, the quality and so on various concerted effort cooperation,
the foothold existing equipment, overcomes many difficulties, maximum limit displays the installed capacity,
achieves earnestly according to the significant variety requests the organization to produce, according to
high quality highquality goods standard strict quality of certified level. In 5 month's, researches and develops
150mm, 185mm, 215mm successively and so on different thickness specification A514GrQ, and authenticates
smoothly through the ABS classification society. Presently, the domestic similar enterprise can produce this
variety steel the greatest thickness is 177.8mm
