A514 Gr E quenched and tempered steel, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
Our company was founded in 2000, which initially committed to providing high-quality steel A514 Gr E quenched and tempered steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A514 Gr E quenched and tempered steel steel to the international market, opening up the international steel market.
A514 Gr E quenched and tempered steel, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape.This strength is greater than that of ordinary steel. Tensile strength is 550-720MPa, elongation: 17%, Q460 material is made by adding Cr, N, V, Ti and other alloying elements on the basis of 16Mn steel.
High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of A514 Gr E quenched and tempered steel, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
