The steel plate for water conservancy and power generation is used for ring seat, motor support structure, ship lock gate and discharge chute volute of large water conservancy generating units; the representative steel grades are S500Q, S550Q, SA516, etc., which require flaw detection and have Z-direction performance requirements; the main specifications are thickness of 120mm, 180mm, 200mm, 215mm, 270mm, and the maximum width is 4400mm. The representative steel grades of wind power steel plates include Q345E, Q690E, high strength RF 36 hull steel plate, etc.; the main specifications are thickness of 80mm, 100mm, 110mm, 120mm, 140mm, 160mm, 180mm, 200mm, 240mm, 260mm, 280mm, 300mm, and the width is more than 2500mm.
Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.
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 high strength RF 36 hull steel plate, 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.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. high strength RF 36 hull steel plate, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
