Mining & Quarry - Mine - Bucket 3m³ - Mobile equipment - Sweden - +94% lifetime

Objective

Demonstrate the advantages of Creusabro^® 8000 and Creusabro® Dual over standard 450 HB and 500 HB water-quenched steels in a bucket application, with the aim of extending wear life and reducing operating costs.

Test Conditions

• Location: Gravel and aggregate production site in Sweden

• Environment: Continuous exposure to highly abrasive materials under demanding weather conditions, including moisture and freezing temperatures.

• Function: Bucket wear parts subjected to constant abrasion and impact during loading and transport of material.

• Original material: 450 HB & 500 HB water-quenched steels

• Replacement material: Creusabro® 8000 and Creusabro® Dual, plasma cut and welded.

Results

• Wear parts made from Creusabro® 8000 and Creusabro® Dual achieved a total of 450,000 tons of material handled, compared to 230,000 tons with the original 450 HB & 500 HB steels — a 94% increase in service life.

• The switch required no changes to the standard fabrication process, maintaining ease of production and installation.

Value Delivered

• Nearly Doubled Wear Life: 450,000 tons handled before replacement, reducing maintenance frequency and downtime.

• Cost Efficiency: Fewer parts required and less time spent on replacements translated into significant savings on both materials and labor.

• Operational Continuity: Longer-lasting wear parts minimized interruptions and boosted productivity, even in harsh Swedish conditions.

• Ease of Fabrication: Plasma cutting and welding processes remained simple and compatible, facilitating the transition.

Conclusion

By choosing Creusabro® 8000 and Creusabro® Dual, LedinsGrus AB and Bergsmekaniska unlocked a high-performance, cost-efficient, and durable solution for their bucket wear parts — achieving nearly double the service life and reducing total operating costs.

Once again, Creusabro® steels deliver measurable technical and economic benefits, proving to be the smart choice for demanding quarry applications.
