2020.12.22EN 10025-6 high strength steel 1.8940 industry new technology

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. EN 10025-6 high strength steel 1.8940, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. EN 10025-6 high strength steel 1.8940, 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.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. EN 10025-6 high strength steel 1.8940, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

The related factors of EN 10025-6 high strength steel 1.8940 steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different EN 10025-6 high strength steel 1.8940 steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
