What Customers Say About Qilu Tool Steel

FAQ

Tool steel is a type of steel specifically designed to make tools with excellent hardness, wear resistance and strength. Compared to plain steel, tool steel has a more complex alloying composition, with elements such as chromium, molybdenum and tungsten often added to enhance its properties. Plain steels are typically used for structural and construction purposes and have high strength and toughness, but are weak in wear resistance and heat treatability.

Yes, we offer customization service for our tool steel products. Customers can choose different compositions, hardnesses and sizes to meet various industrial requirements based on specific needs and applications. We are committed to providing the most suitable solutions for our customers.

Alloy tool steels, such as M2 or H13, typically perform best at high temperatures. These steels retain their hardness and toughness at high temperatures and are suitable for hot work and high temperature working environments, such as mold and tooling.

We ensure the quality of our tool steels through a rigorous quality control process that includes testing of raw materials, monitoring during production and performance testing of the final product. In addition, we follow international standards to ensure that each batch meets customer requirements and industry standards.

The hardness and toughness of a tool steel are key factors in its serviceability. Higher hardness increases the wear resistance of a tool, making it less likely to wear out when cutting or impacting. Toughness, however, affects the tool’s ability to withstand impact or load, and excessive hardness can lead to brittle fracture. Therefore, balancing the two is critical for different applications.
