Energy

Energy steel is a key foundational material for the energy industry, providing strong support for the implementation of China's energy strategy relying on its excellent strength and toughness, corrosion resistance, and weldability. Energy is an important foundation for national economic development. With the depletion of traditional onshore and coastal energy resources and the rapid development of clean energy (such as wind power and hydropower), energy equipment is gradually shifting towards deep sea oil and gas extraction, long distance transportation, high temperature and high pressure petroleum processing, and large scale development, placing stringent requirements on special steel in this field for large size, corrosion resistance, high strength, high toughness, weldability, long service life, and high reliability.
