Garg Steels, located in Chennai, India, stands out as a leading manufacturer and supplier of high-performance Tool and Die Steel H13 Bars. These bars are celebrated for their remarkable toughness, resistance to thermal fatigue, and strength even at high temperatures. H13 is a chromium-molybdenum hot work steel that excels in situations where rapid heating and cooling cycles are common. At Garg Steels, every H13 Bar is crafted with precision from top-quality raw materials and undergoes rigorous testing to ensure it meets global industry standards. Available in a variety of sizes and specifications, these bars are perfect for demanding applications like die casting, extrusion tooling, and hot forging.
Tool and Die Steel H13 Bars generally contain 0.32–0.45% carbon, 4.75–5.50% chromium, 1.10–1.75% molybdenum, 0.80–1.20% vanadium, along with trace amounts of silicon and manganese. This well-balanced composition gives H13 its high toughness, wear resistance, and red hardness, making it ideal for hot work environments. The bars maintain their mechanical integrity at temperatures reaching up to 600°C and provide excellent thermal shock resistance. Offered in either an annealed or hardened state (44–52 HRC), H13 Bars from Garg Steels guarantee consistent performance for precision tooling and die applications that demand high durability and thermal strength.

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.
Tool and Die Steel H13 Bars are widely utilized in hot work applications thanks to their thermal fatigue resistance and outstanding toughness. They are commonly found in die-casting dies, extrusion dies, forging dies, and hot shear blades. Additionally, they are used in plastic mold tooling that requires a long service life and can withstand high operating temperatures. H13 Bars are perfect for creating inserts, cavities, and core pins. Industries such as automotive, aerospace, and die-making depend heavily on H13 steel for its strength, stability, and performance. Garg Steels offers precision-engineered H13 Bars designed specifically for challenging industrial environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
