Chuck Metals, a top-notch manufacturer and supplier based in Singapore, Pulau Ujong, specializes in high-quality Tool and Die Steel H13 Bars that are perfect for demanding hot work applications. H13 tool steel is celebrated for its remarkable blend of toughness, heat resistance, and dimensional stability. At Chuck Metals, you can find H13 bars in various sizes and heat-treated conditions, all meeting standards like ASTM A681. These bars are a go-to choice for die casting, extrusion, and forging due to their impressive wear resistance at high temperatures. With precision grinding and quality assurance, Chuck Metals’ H13 bars are built to withstand thermal and mechanical stress in various industries.
H13 Tool Steel Bars are made up of about 0.32–0.45% carbon, 4.75–5.5% chromium, 1.1–1.75% molybdenum, 0.8–1.2% vanadium, along with balanced amounts of manganese and silicon. This steel boasts a hardness range of 44–52 HRC and a tensile strength of approximately 1450–1650 MPa, along with good impact resistance. It retains its mechanical properties even at temperatures over 600°C, making it a top choice for hot work applications. H13 also excels in thermal fatigue resistance, minimizing the chances of cracking or distortion during quick heating and cooling cycles.

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.
H13 tool and die steel bars are used extensively in industries that demand high toughness, strength, and heat resistance. These are mainly found in the production of hot-working tools, namely dies, molds, and extrusion tools for aluminum, zinc, and magnesium. H13 bars are great for forging dies, die-casting molds, and plastic injection molds because of their excellent thermal stability and resistance to cracking due to thermal stress. Moreover, H13 steel bar exhibits application in punches, shear blades, and cutting tools by their resistance towards wear and abrasive characteristics. Therefore, they hold high significance because of the temperature stability with high hardness and retention for applications where tooling should be of good precision.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
