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 widely used in industries that require exceptional toughness, strength, and resistance to heat. They are commonly applied in the production of hot-working tools such as dies, molds, and extrusion tools for aluminum, zinc, and magnesium. Thanks to their outstanding thermal stability and resistance to cracking under thermal stress, H13 bars are ideal for forging dies, die-casting molds, and plastic injection molds. In addition, their wear resistance and abrasion tolerance make them suitable for punches, shear blades, and cutting tools. With excellent temperature stability, high hardness, and reliable retention, H13 steel bars are vital for precision applications where durability and accuracy are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
