Steel grades by a letter on behalf of "Wugang heavy plate WH, tensile strength values, The Quenched symbols Q and quality rating symbols and other order. Widely used in all types of machinery, buildings, vehicles, ships, important structural parts. In order to meet its large, lightweight development requirements, quenched and tempered steel toward a higher intensity level development, performance swap tempered steel cutting, welding, lamellar tearing resistance, anti-aging Sensibility more high demand. Quenched and tempered steel WH80Q Wugang developed with high strength, good low temperature impact toughness, resistance to lamellar tearing performance, lower timeliness sensitivity coefficient. The chemical composition of the adopt low-carbon low-alloy steel design, the use of controlled rolling and controlled cooling technology, carbon equivalent and the welding crack sensitivity coefficient to make WH80Q lower than conventional quenched and tempered steel. Quenched and tempered high strength steel: WH70Q A514GrF WH80Q Q690D WQ690D WQ700D S690Q WH100Q Q890 Q960 steel suitable for requirements of the good weldability coal mine hydraulic support, engineering machinery, hydropower pressure tube steel structure. The company adhere to the "quality first, quality service, honesty, customer first" purpose, and also engaged in a variety of Wuhan Iron and Steel, Anshan Iron and Steel Company, Chongqing Iron and Steel, Baosteel special wide-thick steel plate material. Available sizes: Thickness 8-650mm, width of 1.5-4.02m, length 3-27m unit weight up to 35 tons, according to user requirements set rolling futures, and for many years to spot stocks a large variety of materials (including genuine plate and short foot board) also cut drawn Act and shaped pieces of finished or semi-finished products delivery and transport agents according to user requirements. Invites new and old customers with our hand with both hands and common development, and create a win-win situation. Welcome to call us stock futures, large favorably.
