We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product A709 Gr 100W bridge steel plate annual capacity is 200 thousand tons.
One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making A709 Gr 100W bridge steel plate steel business. The talks will be announced Monday as part of a strategic reform that could include closing or selling assets. Previously, ThyssenKrupp steel Europe, Germany's largest steelmaker, announced a loss in the first half of the group three point seven two 100 million euros four point zero two Billion US dollars). ThyssenKrupp has continued to advocate the benefits of A709 Gr 100W bridge steel plate steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as A709 Gr 100W bridge steel plate. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.Excellent welding performance of Q960 quenched and tempered steel: The composition design minimizes the carbon content and thermal sensitivity coefficient to improve the welding performance. So, A709 Gr 100W bridge steel plate, Q960 steel has excellent welding joint performance, which can meet the welding requirements of bridges, buildings, cranes, shipbuilding, vehicles and large structural parts.
