In March 2015, Wugong steel ranked among eight bidding steel enterprises worldwide in terms of its total score, including product technical quality and price, in the bidding for 780MPa grade hydropower high strength steel of Wudong Hydropower Station.The contract of 11,000 tons of steel for 780MPa grade pressure steel pipe for Wudong Hydropower station is full.Subsequently, the state Grid project in Hebei Fengning, Jilin Donghua two giant hydropower stations 780MPa grade hydropower steel 13,000 tons of orders were also delivered to Wugang production.
SX780CF牌号讲解:高强钢SX780CF牌号表示:”SX“代表三峡的意思。这是舞阳钢铁公司为三峡集团乌东德水电站建设使用780MPa级高强钢SX780CF。这是当前国际上批量应用的水电钢,只有国外少数几家钢企具有批量供货的业绩。
SX780CF钢板可附探伤:也被称为超声波检验,是针对钢板内部质量的一种检验方法手段,同时也可以检验出金属内部的缺陷如隐蔽裂纹、气孔、沙眼和杂质等。
SX780CF化学成分:
SX780CF钢板需具备高强韧性、良好冷变形性及焊接性。设备制造要求强度等级高,可焊性能强。由于水电用钢使用环境特殊,对钢板的强度、焊接性能、耐腐蚀性能等要求非常严格。上述钢板力学性能要求在较高的强度下,具备良好的低温冲击韧性、断裂韧性和良好的焊接性能,研发难度极大。
SX780CF力学性能:
SX780CF应用SX780CF属于高强度低裂纹敏感性钢,主要用于装机容量达千万千瓦以上大型水力发电机组和高水头蓄能电站中蜗壳、压力钢管等重要结构件制造,
