What Is Qilu D2 Tool Steel?
Qilu D2 tool steel is a high-carbon, high-chromium alloy tool steel that is known for its outstanding hardness and wear resistance. Manufactured by Qilu Steel, this steel grade is designed to offer exceptional performance in tools and dies that require high strength and durability. It is commonly used in applications where resistance to abrasion and deformation is crucial.
Key Properties of Qilu D2 Tool Steel
- High Hardness: Achieves a Rockwell hardness of approximately 60-62 HRC.
- Excellent Wear Resistance: Resists abrasion and wear, making it ideal for cutting and forming tools.
- Good Toughness: Maintains its toughness and impact resistance under high stress.
- High Chromium Content: Enhances corrosion resistance and stability at high temperatures.
Benefits of Using Qilu D2 Tool Steel
Choosing D2 tool steel for manufacturing offers several advantages that make it a superior material for various applications. Here’s how it stands out:
Exceptional Wear Resistance
Qilu D2 tool steel’s high chromium content provides superior wear resistance. This makes it ideal for applications involving high friction and abrasion, such as cutting tools, dies, and stamping components. Its ability to maintain sharp edges and resist surface degradation extends the lifespan of tools and reduces maintenance needs.
High Hardness and Strength
With a Rockwell hardness of 60-62 HRC, D2 tool steel is extremely hard and capable of withstanding significant mechanical stress. This hardness is crucial for tools that need to retain their shape and cutting edges under rigorous use, ensuring reliable performance and longevity.
Improved Dimensional Stability
The high chromium content in Qilu D2 tool steel contributes to its dimensional stability. This property ensures that the steel maintains its shape and size even under fluctuating temperatures and stress, making it ideal for precision manufacturing applications.
Good Toughness
Despite its high hardness, Qilu D2 tool steel offers good toughness, which helps prevent cracking and chipping under impact. This balance of hardness and toughness makes it suitable for applications where both properties are required.
Enhanced Corrosion Resistance
The chromium content in Qilu D2 tool steel also provides improved corrosion resistance compared to other tool steels. This feature is particularly beneficial in environments where exposure to moisture and corrosive elements is a concern.
