Recently, Baosteel succeeded in trial production of 1,400 mpa ultra high strength plate, which represents the leading technology in the world. And the products are proved to meet the design standards, which means Baosteel fills the blank of high strength plate production in China, and becomes one the few companies that have such technology.
With a yield strength of more than 1,200 mpa and a tensile strength of more than 1,400 mpa, this ultra high strength plate is the highest grade plate with the highest strength, high toughness, good welding and forming performance, and can be used to make the key force bearing parts of engineering machines. Due the difficulties in component design and producing, the capability of producing 1,400 mpa plate is an important step to become a first level plate manufacturer in the world.
With a rapid development of manufacturing industry in China, the demand for welding structure steel with higher strength for engineering machines increased. Therefore, Baosteel began the development of 1,400 mpa ultra high strength plate in September 2007, and succeeded in trial production of 1,300 mpa plate at the end of 2007. Basing on this, the company finally succeeded in trial production of ultra high strength plate with a tensile strength of more than 1,400 mpa.
