High-performance Tool and Die Steel P20 Bars are the speciality of Delhi, India-based Rupal Metals, a renowned manufacturer and supplier. Rupal Metals’ P20 Bars are renowned for their exceptional toughness, polishability, and machinability. They are designed to satisfy the demanding requirements of the moulding and tooling industries. The company provides P20 Bars in a range of sizes and specifications to meet a variety of industrial needs, with an emphasis on quality assurance and customer-centric service. Rupal Metals is a reputable brand among toolmakers and die manufacturers in India and abroad because of its dedication to providing precision-engineered, premium-grade steel solutions.
Carbon (0.28–0.40%), chromium (1.40–2.00%), molybdenum (0.30–0.55%), manganese (0.60–1.00%), and silicon (0.20–0.80%) are the usual constituents of tool and die steel P20 bars. These alloying elements offer uniform hardness, exceptional toughness, and resistance to wear. Mechanical characteristics include good dimensional stability, a yield strength of about 835 MPa, and a tensile strength of about 965 MPa. Because the steel is typically supplied pre-hardened (~280–320 HB), it can be used right away in tooling applications without requiring further heat treatment.

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.
Because of their exceptional strength, durability, and machinability, tool and die steel P20 bars are used extensively in the mold-making and tooling industries. They are perfect for producing blow moulds, die-casting dies, extrusion dies, and injection moulds made of plastic. P20 Bars are also utilised in tools that need to be highly polished and have precise tolerances, like moulds for consumer electronics, home appliance parts, and automobile components. They are appropriate for high-production settings because of their pre-hardened state, which lowers processing time and expense. Long service life and reliable performance under demanding working conditions are also guaranteed by their superior dimensional stability and wear resistance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
