GB/T1591 Q420C Carbon and low alloy steel round bar, Q420C steel bar Diameter
GB/T1591 Q420C Carbon and low alloy steel round bar is a high strength low alloy structural steel. Q420C steel bar is not only a high-strength steel, it is low-carbon steel, but its tensile strength is a little increased. Q420 has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold formability and weldability; has good corrosion resistance and engage in a certain wear resistance.
Q420C steel bar is used in Construction of bridges, highway construction and other engineering construction. Q420C steel is adapted to the power tower, various types of cranes, heavy vehicles, oil derrick, high temperature fan, large shovels, dump trucks and drilling rigs, hydraulic support, steel, etc.
