15MnV High Speed Steel Bar
15MnV belongs to low-alloy high-strength structural steel. It is an alloy structural steel developed by adding a small amount of alloying elements on the basis of carbon structural steel. The strength of 15MnV alloy structural steel is higher than that of carbon structural steel, which can reduce structural weight and save steel; it has sufficient plasticity, toughness and good welding performance; it also has good corrosion resistance and low cold brittle transition temperature.
15MnV, 15MnTi and 16MnNb are low-alloy high-strength steels of the same grade. The new grade of these three steels is Q390. If it is not used for low temperature, 10MnPNbRE can also be used instead.
