P20 tool steel bars are primarily made up of Carbon (0.28–0.40%), Chromium (1.40–2.00%), Manganese (0.60–1.00%), Molybdenum (0.30–0.55%), along with trace amounts of Silicon, Phosphorus, and Sulfur. This blend provides outstanding machinability and polishability. On the mechanical side, P20 steel boasts a tensile strength of about 965 MPa and a hardness ranging from 28 to 32 HRC in its pre-hardened state. It also shows good toughness, dimensional stability, and wear resistance, making it a great choice for various mold-making applications, with the option for further heat treatment if increased hardness is desired.

P20 tool steel bars find extensive use in creating plastic injection molds, pressure die casting dies, and extrusion tools. Their superb machinability and polishability make them perfect for crafting intricate molds with excellent surface finishes. P20 is also utilized for die holders, backers, and bolsters due to its strength and wear resistance. Additionally, it plays a vital role in producing tools for the automotive and consumer electronics sectors, where precision and durability are paramount. P20’s capability to be nitrided or surface-hardened further enhances its performance in demanding applications.
