GB11263-89 Q345E H Beam with Large Stock

Q345E is a kind of low alloy with high strength steel. Q345E H Beam has good low temperature impact performance, and Q345E steel grade include three parts: the Chinese phonetic alphabet, yield strength value, and symbol of quality grade.

Q345E Application:

Q345E H Beam is mainly used for Engineering machinery, mining machinery, metallurgical environmental protection, water conservancy and hydropower, rail equipment and other structural parts.

Chemical Composition of Q345E H Beam
