Matters need attention in use of S700MC steel for large truss truck boom

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.

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, S700MC steel for large truss truck boom, 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.

The S700MC steel for large truss truck boom, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For S700MC steel for large truss truck boom medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
