Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. EN steel S355ML, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. EN steel S355ML, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. EN steel S355ML, 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.

The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of EN steel S355ML, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.
