Q235 Q355 Angle Channel Beam
Q235 angle steel belongs to the low strength steel. Its yield strength is 235Mpa, which is relatively low in steel materials, than it is high strength steel such as Q345 belongs to medium strength steel, and then higher strength such as Q420D for higher strength steel, and there are more special ultra-high-strength steel such as GC-4 steel, whose tensile strength reaches 1765~1961Mpa.
Q355 Angle steel is a kind of low alloy high-strength structural steel, which is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc., in which "Q" stands for yield strength, and 355 indicates that the yield strength of this steel is 355MPa.
Angle steel is a kind of carbon structural steel for construction. It is a type of section steel with simple cross-section. In use, it is required to have good weldability, plastic deformation properties and certain mechanical strength. The raw material billet for the production of angle is low carbon billet, and the finished angle is delivered in hot rolled, normalised or hot rolled condition.
