For crucial tooling and engineering applications, Neil Metals, a top manufacturer and supplier with headquarters in Kolkata, India, provides high-quality Tool and Die Steel H13 Bars. H13 bars from Neil Metals are used all over the world in hot work tooling where strength and thermal stability are essential because of their excellent performance under thermal shock and abrasion. Neil Metals offers H13 tool steel bars in a range of sizes and specifications with an emphasis on quality, dimensional accuracy, and prompt delivery. The business serves the various needs of the forging, die casting, and extrusion sectors in India and abroad.
Die steel and tools Chromium-molybdenum-vanadium alloyed hot work tool steels are known as H13 bars. They typically contain 0.80–1.20% vanadium, 4.75–5.50% chromium, 1.10–1.75% molybdenum, and 0.32–0.45% carbon. H13 provides outstanding toughness, high hardenability, and good resistance to thermal fatigue. The steel reaches a hardness range of 48–52 HRC following appropriate heat treatment. It is appropriate for demanding thermal and mechanical conditions because it retains strength and ductility at high temperatures and shows outstanding resistance to heat checking and abrasion.

When choosing Tool and Die Steel H13 bars, consider factors such as hardness, heat resistance, wear resistance, toughness, machinability, and the specific requirements of the application, including temperature and load conditions.
Tool and Die Steel H13 bars offer limited corrosion resistance due to their high alloy content, but they can still be susceptible to rusting in harsh environments. To improve corrosion resistance, they may require additional surface treatments like coating or regular maintenance to prevent degradation.
Because of their strength and thermal stability, tool and die steel H13 bars are frequently used in hot work applications. They are perfect for producing punches, mandrels, die casting dies, extrusion dies, and hot forging dies. H13 bars are also utilised in plastic moulding, where high temperatures and pressures are applied to the tools. H13 steel is used for vital parts like die inserts, cores, and support tools in the heavy engineering, automotive, and aerospace industries. It is essential for both hot and cold tooling operations because of its resistance to thermal shock and cracking, which guarantees longer tool life and reliable performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
