Delivering top-notch Tool and Die Steel P20 Bars for the mould and die-making industries is the area of expertise for Neil Metals, a reputable manufacturer and supplier in Kolkata, India. Neil Metals offers pre-hardened, machining-ready P20 tool steel bars with an emphasis on accuracy, reliability, and durability. Because of their exceptional toughness and polishability, these bars are frequently used for die-casting components, injection moulds, and plastic mould bases. Neil Metals is a dependable partner for engineering, automotive, and tooling applications because it serves both domestic and foreign markets and guarantees high quality standards, fast turnaround, and technical expertise.
A low-alloy chromium-molybdenum steel, P20 tool steel normally has 0.28–0.40% carbon, 1.40–2.00% chromium, 0.90–1.20% manganese, and 0.30–0.60% molybdenum. It has a hardness of 28–32 HRC and is delivered pre-hardened, providing a good mix of toughness and machinability. P20 steel has a high tensile strength, moderate wear resistance, and excellent polishability. It is perfect for detailed mould cavities and dies because it also exhibits good dimensional stability during machining. The material retains its structural integrity and finish quality even when subjected to high injection pressures.

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.
In the plastic injection moulding industry, tool and die steel P20 bars are widely used to create mould bases, cavities, and dies for thermoplastics and thermosets. They are perfect for mould components that need a smooth surface finish because of their exceptional polishability and consistent hardness. Additionally, they are utilised in tooling plates, holder blocks, compression moulds, and die-casting dies. Furthermore, because of its durability and dimensional stability, P20 steel can be used for electronic housings, medical device casings, and automotive components. It is a preferred material for precision-engineered mould tools and high-volume production because of its ease of machining, which shortens lead times.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
