GB/T Q345E low alloy high strength steel round bar Length

Q345E steel round bar is a low alloy high strength steel, has good low temperature impact properties; Q345E low alloy high strength steel round bar by the representative of the yield strength of the Chinese phonetic alphabet, yield strength, composition quality rating symbols three parts. Wherein, Q represents the yield strength; 345 represents the yield strength, the unit MPa; E represents level (impact test by -40 degrees).

When the request Q345E low alloy high strength steel bar with a thickness property, then the steel grades together with representatives of the thickness direction (Z direction) performance level of symbols, for example: Q345EZ15. When the need for heat treatment requirements, such as normalizing, the designation suffix N in steel, commonly used + N, eg: Q345E + N.
