Q345 steel has the advantage of being mildly tempered and easy to form and weld.Q345 steel is a Chinese standardized low-alloy, medium tensile strength steel made by the hot rolling process and used for a variety of fabrication applications. To some extent, Q345 has the same properties and composition as ASME A572, i.e., Q345 is equivalent to A572.
Q345 steel covers the standard requirements for grades 42, 50, 55, 60, and 65 of high-strength, low-alloy structural steel shapes, plates, and sheets for bolted, welded, and riveted structures in bridges and buildings.
requirements.
Q345 is a steel with a carbon content of less than 0.2%, a silicon content of less than 0.55% and an impurity content of less than 0.55%. This special grade of steel is a versatile manufacturing steel in the field of construction equipment.
