GB T1591 Q345D steel has good low temperature mechanical properties

GB T1591 Q345D steel has good comprehensive mechanical properties, and is widely used in bridges, ships, power plants, boilers, pressure vessels, oil tanks, lifting machinery and other aspects. With the vigorous call of the state for the use of clean energy, wind power generation has been paid more and more attention.

Many wind power plants are facing the test of low temperature. In some places the temperature can be below - 30 C. At low temperature, the operation conditions, performance of components and maintainability of units will change correspondingly, which may cause wind turbines to exceed the allowable range of original design, and serious safety accidents may occur when the situation is serious.

GB T1591 Q345D steel is the main material of wind turbine tower, and the steel has good low temperature mechanical properties.
