9Mn2V Cold Work Tool Steel

9Mn2V is a cold-work die steel containing alloying elements such as manganese (Mn) and vanadium (V); it is widely accepted due to its well-balanced chemical composition, uniform microstructure, and stable properties following heat treatment.
 
Materials with properties similar to 9Mn2V include:
CrWMn: Hardenability is improved by increasing chromium content.
9CrWMn: Slightly higher carbon and chromium content, resulting in superior wear resistance.
MnCrWV: A more uniform microstructure is achieved through composite alloying. These materials achieve similar levels of hardness and wear resistance, and can be selected based on specific processing requirements.
 
Chemical Composition of 9Mn2V Steel:
C ≈ 0.85%–0.95%, Mn ≈ 1.80%–2.10%, Si ≈ 0.20%–0.50%, V ≈ 0.15%–0.30%; the remainder consists of Fe and trace impurity elements.
 
When combined with appropriate heat treatment processes, 9Mn2V steel can achieve a hardness of HRC 58–62 while maintaining a certain level of fracture toughness—a characteristic of particular importance for precision stamping dies.
 
9Mn2V is primarily used for cold-work dies, such as precision stamping dies, cold shears, shear blades, gauges, and complex-shaped forming dies.
