Information

In the rapidly evolving field of additive manufacturing, Mold Steel 18Ni300 Powder, as a specialized alloy, has achieved significant technological breakthroughs, opening up new possibilities for mold manufacturing and other industrial sectors. This article delves into the developmental stages of 3D printing for mold steel materials and applications, specifically focusing on the unique properties of 18Ni300 within this context.

Development Stages of 3D Printing in Mold Manufacturing:

Injection Mold Stage:

- Early Development: 3D printing technology gradually applied to the manufacturing of injection molds, providing flexibility for producing customized injection-molded components.

- Material Requirements: Emphasis on wear resistance, high-temperature resistance, and mechanical performance to meet the demanding requirements of the injection molding process.

Die Casting Mold Stage:

- Application Expansion: 3D printing technology offers a more flexible production method in die casting mold manufacturing, catering to the needs of complex-shaped castings.

- Elevated Material Requirements: Increasing demands on mold materials, requiring higher resistance to heat fatigue and corrosion.

Stamping Die Stage:

- Broadening Applications: 3D printing technology applied in stamping die manufacturing, enabling the production of complex, high-precision stamped parts.

- Further Increased Material Requirements: Mold steel materials need higher hardness, strength, and wear resistance to meet the requirements of the stamping process.

Unique Properties of Mold Steel 18Ni300 Powder:

18Ni300 is a typical martensitic age-hardening steel, commonly used in special engineering and manufacturing applications. In comparison to traditional mold steel alloys used in forging and casting, such as Corrax and H13, 18Ni300 exhibits some clear advantages.

 

Unique Properties Include:

- No or Extremely Low Carbon Content: 18Ni300 avoids printing cracks caused by carbon elements in additive manufacturing, enhancing the stability of the manufacturing process.

- Precipitation Hardening of Intermetallic Compounds: Achieves ultra-high strength through the precipitation hardening of intermetallic compounds, suitable for applications with high strength requirements.

- Good Formability: Martensitic aging imparts good formability to 18Ni300, making it excel in manufacturing complex parts.

- Excellent Metallurgical Bonding and Wear Resistance: Martensitic aging steels typically have good metallurgical bonding, and 18Ni300 may have better wear resistance, improving the durability of mold materials.

 

Key Application Industries:

The Mold Steel 18Ni300 Powder demonstrates significant potential in mold manufacturing and industries such as automotive. Its heat resistance, high strength, and corrosion resistance make it an ideal choice for mold and forming applications. In the automotive industry, it enhances the performance and durability of critical components.
