What is the mechanical properties of 25CrMoS4 steel flat bar?

We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments. Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.

Good weldabilityBecause of its low carbon content, low alloy element content, good plasticity and low hardenability, this material 25CrMoS4 steel flat bar is not suitable to have quenching structure or crack at the weld. The cold and hot pressure processing performance is good. Because of its good plasticity and small deformation resistance, it is not easy to produce cracks after pressure processing. Good corrosion resistanceUnder various atmospheric conditions, it has higher corrosion resistance than carbon steel.

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 25CrMoS4 steel flat bar, 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.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
