Maximize service life and efficiency with QUARD

In mining, every hour of downtime has a cost — and every structural failure carries a risk. That’s why QUARD is the smart choice for abrasive and high-impact conditions. Engineered for extreme wear resistance, it delivers exceptional durability even under continuous, heavy-duty use, helping extend equipment lifespan and reduce unplanned maintenance.

With hardness levels up to 550 HB, QUARD allows manufacturers to design components that are both lighter and longer lasting, significantly improving operational efficiency in mining environments.

Why QUARD makes the difference in mining

Mining operations place enormous stress on materials, from the constant friction of hard rock to the repeated shocks absorbed by mobile equipment. QUARD’s martensitic microstructure, high purity, and precision-controlled production process make it ideally suited for these demands.

Key benefits include:

  • Outstanding abrasion resistance up to 550 HB
  • Consistent toughness for high-impact applications
  • Superior workability for easier processing in the workshop

Typical applications:

  • Excavator buckets and blades
  • Tunnel boring tools
  • Dump truck bodies
  • Crusher linings
  • Conveyor chutes and hoppers

By choosing QUARD, equipment manufacturers and mining operators can:

  • Extend service life up to 3× compared to conventional structural steel
  • Reduce structural weight by up to 40%, increasing payload and lowering fuel consumption
  • Improve fabrication speed thanks to excellent cutting, welding, and bending properties

QUARD PRO, THE PREMIUM CHOICE FOR TOUGH MINING CHALLENGES

For mining applications that demand both higher resistance and better workshop productivity, QUARD PRO provides the perfect balance.

 

Positioned between QUARD 450 and QUARD 500, QUARD PRO offers:

  • A hardness close to 500 HB
  • Workability levels similar to QUARD 450
  • High impact toughness, ensuring reliability in dynamic loading conditions

This makes it ideal for complex mining components that must endure severe wear but still require intricate fabrication or field repairs.

With QUARD PRO, manufacturers can:

  • Achieve superior wear performance without compromising ease of forming and welding
  • Reduce preheating needs and improve welding speed
  • Increase consistency and predictability during equipment assembly

In short: less downtime, less rework, more productivity.
