P20 steel is a versatile and widely used pre-hardened tool steel, primarily known for its excellent machinability, uniform hardness, and good toughness. With a balanced composition that includes carbon (approximately 0.4%), chromium (around 1.8%), and molybdenum (about 0.4%), P20 steel offers a good combination of strength and ductility. It is typically delivered in the pre-hardened condition to a hardness of 28-32 HRC, which eliminates the need for further heat treatment and reduces the risk of distortion during machining. P20 steel is commonly used in the manufacture of plastic injection molds, die casting tools, and other precision tooling applications where dimensional stability and a polished finish are essential. Its consistent performance and ease of fabrication make it a popular choice in the tool and die industry.
