Vacuum Brazing of CR12MoV Tool Steel with Tungsten Carbide

Tooling and die components operating under severe wear and impact conditions require materials that combine toughness with extreme hardness. Vacuum brazing CR12MoV tool steel with tungsten carbide provides an effective solution for manufacturing high-performance tools.

Normantherm supports this process with advanced vacuum brazing furnace technology.

Advantages of Vacuum Brazing for CR12MoV and Tungsten Carbide

Conventional welding methods can cause oxidation, cracking, or weak joints when joining carbide to tool steel. Vacuum brazing eliminates these issues by providing a clean and controlled environment.

Key benefits include:

• High-strength metallurgical bonding
• Uniform carbide-to-steel interfaces
• Reduced risk of thermal cracking
• Improved tool durability and wear resistance

These advantages are critical for tooling reliability.

Material Properties and Performance

CR12MoV is a high-carbon, high-chromium cold work tool steel known for its excellent hardenability and wear resistance. Tungsten carbide offers extreme hardness and abrasion resistance, making it ideal for cutting and forming edges.

Vacuum brazing enables these materials to work together effectively in demanding applications.

Applications in India’s Tooling Industry

Vacuum brazed CR12MoV and tungsten carbide components are widely used in India’s manufacturing sector for:

• Cutting and blanking dies
• Cold forming tools
• Wear-resistant inserts
• Heavy-duty industrial tooling

As production volumes increase, consistent joint quality becomes essential.
