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 Industries that demand extreme toughness, heat resistance, and wear durability frequently use steel bars. They are perfect for hot-working applications like extrusion tools for metals like magnesium, zinc, and aluminum, die-casting molds, and forging dies. They work well with plastic injection molds, punches, shear blades, and cutting tools because of their stability at high temperatures. H13 bars offer superior resistance to wear and thermal cracking, guaranteeing accuracy and durability in tooling operations. Because of these characteristics, they are crucial in the manufacturing, automotive, and aerospace industries where tools must withstand high levels of stress and frequent thermal cycling.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
