A709 Gr 100 bridge steel plate,St52-3 steel is low alloy high strength steel. The main characteristics of St52-3 steel are high tensile strength and yield point. St52-3 steel is used in civil construction, underground engineering, bridge structure, ocean structure, container manufacturing, automobile and machine manufacturing. Based on the principle of quality oriented, the company has established a perfect quality standard inspection system to provide customers with high-quality and low-cost steel products and after-sales services, which has been supported and praised by new and old users from all walks of life.A709 Gr 100 bridge steel plate
A709 Gr 100 bridge steel plate,The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. The large-diameter thick wall steel pipes purchased by us are long or short. If they are short, they can be welded. If they are long, they need to remove the redundant parts, that is, cut them out. Their length is suitable for the length required by the construction of steel pipes.
A709 Gr 100 bridge steel plate,"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."
The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with high-quality steel plates, the excellent quality from specialty.
