Duplex-VARIANTIC®-1400 – Increase the number of strokes of your tools

Thanks to the growing importance of lightweight design, high-strength and ultra-high-strength sheet steel is being used more and more frequently.

The processing of high-strength steel grades presents users and toolmakers with new challenges, as the high sheet strength places an extreme load on the tools. The risk of wear increases and with it the risk of shorter tool life and costly production downtime. A solution to this challenge is provided by particularly robust materials with a more extensive property profile and PVD coatings, which increase tool productivity.

New Duplex-VARIANTIC®-1400 has been developed specifically for forming sheets with tensile strengths ranging between 1,000 and 1,400 MPa. It guarantees improved and reliable tool performance when it comes to these steel sheet grades.

Coating properties

Advantages

• Up to 460 % better durability compared to other coating solutions
• Al (Cr, Ti) N-based PVD coating with specifically adapted adhesion and top layer
• Plasma pretreatment of the tool within the coating process to increase the supporting effect based on the unique voestalpine eifeler Duplex process
• Excellent resistance against abrasive and adhesive wear in the cold forming of galvanised sheet steel with tensile strengths of up to 1,400 MPa and above
• Excellent adhesion
• Optimal assurance of the smooth cut proportion during fine blanking
