What are the special requirements of steel in the energy industry?

The energy industry has some special requirements for steel to meet its performance needs under specific working conditions. Here are some common requirements:

Power and corrosion resistance:

In the energy industry, steel usually requires high strength and corrosion resistance to bear the impact of heavy load and harsh environment. For example, in oil and natural gas mining, steel needs to be able to resist extreme conditions such as saline, acid gas and high pressure.

High temperature performance:

In some energy applications, such as thermal power and nuclear energy, steel needs to maintain its mechanical performance and stability at high temperature. This requires steel to have good high temperature strength, antioxidant and heat -resistant fatigue.

Low temperature toughness:

In low -temperature applications such as liquefied natural gas (LNG) and liquefied petroleum gas (LPG), steel needs to have good low temperature toughness to prevent crisp cracking and break.

Welding performance:

In the energy industry, steel usually needs to be welded. Therefore, steel should have good welding properties, including weldability, welded strength, and toughness of welded joints.

Size accuracy and surface quality: In some key components, such as pipelines and valves, the size accuracy and surface quality of steel are very important to ensure the smooth passage of sealing performance and fluid.

Material certification and quality control:

The energy industry usually requires steel to meet relevant standards and specifications, and strict quality control and testing. This includes testing and certification in the chemical composition, mechanical properties, corrosion resistance of materials.


These special requirements are to ensure that steel can operate safely and reliably in the application of the energy industry, and meet specific working conditions and environmental requirements. Different energy areas and applications may have different specific requirements, so you need to evaluate and select the specific situation when selecting steel.
