Tool and Die Steel P20 Bars are crafted with a blend of carbon, chromium, manganese, and molybdenum, resulting in a well-rounded mix of hardness, toughness, and machinability. Typically, P20 steel features 0.28–0.35% carbon, 1.40–1.60% chromium, 0.60–1.00% manganese, along with trace amounts of nickel and molybdenum. Its mechanical properties boast a tensile strength of 930–1080 MPa, yield strength of 760–850 MPa, and hardness that ranges from 28–32 HRC. These characteristics make P20 bars particularly well-suited for molding and tooling applications, offering outstanding wear resistance, dimensional stability, and ease of machining.

When choosing P20 tool and die steel bars, consider machinability, toughness, hardness, heat treatment capabilities, corrosion resistance, application requirements, cost-effectiveness, and availability of suitable sizes for your specific needs.
Tool and die steel P20 bars are typically sized by their diameter and length, with common diameters ranging from 1 inch to 10 inches, and lengths ranging from 10 to 20 feet.
Tool and Die Steel P20 Bars are extensively utilized in the production of molds, dies, and tooling components for processes like plastic injection molding, die casting, and stamping. Their consistent hardness and excellent polishability make them perfect for high-precision applications that demand minimal deformation. Industries such as automotive, electronics, packaging, and consumer goods depend on P20 steel to create durable and accurate molds. Moreover, its machinability and capacity to undergo heat treatment without sacrificing toughness make it a go-to choice for toolmakers. Starc Metals’ P20 bars ensure reliable performance, minimizing downtime and boosting productivity in industrial manufacturing processes.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
