4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. Q345NQR2 tempered steel, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.
Hot rolled Q345NQR2 tempered steel steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the Q345NQR2 tempered steel processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.
We are committed to providing customers with high-quality services, high-precision products and efficient solutions. If you have any demand for Q345NQR2 tempered steel steel plate, steel pipe and other products, please contact us directly. We are willing to provide you with relevant product knowledge and specific specifications for free. Welcome to purchase.
