Main characteristics of 09MnNiD
The performance of this steel is better than that of 30Mn2 steel. It has higher hardenability, with a critical hardenability diameter of 8-22mm in water, good machinability, moderate cold deformation plasticity and weldability; in addition, the toughness of the steel is not much reduced during heat treatment. But it has quite high strength and wear resistance, especially still high toughness during water quenching; but this steel is highly sensitive to white spots, and has a tendency to temper brittleness and overheat sensitivity during heat treatment.
Application example: This steel is mainly used in quenched and tempered state to manufacture hot stamping parts that require high toughness and wear resistance; it can also be used in normalized or hot rolled supply state, such as tractor track pins.
What kind of steel material is 09MnNiD and what is the standard
09MnNiD is a steel grade imported from Germany. It is a carburizing steel and can also be used as quenched and tempered steel. Hardenability, small heat treatment deformation, good low temperature toughness, good cutting performance, but poor weldability.
