Creusabro abrasion-resistant steel
Extraction, transportation, and handling of bulk products form the foundation of mining industries. Hard rocks and violent impacts often lead to significant wear issues. Creusabro® extends the lifespan of critical components and prevents costly machine downtime.
Creusabro®: In-service hardening, up to +70 HB
Creusabro®: High-temperature resistance: 450°C.
The Creusabro® range is based on an innovative manufacturing process and metallurgy, setting it apart from traditional low-carbon steels.
These wear-resistant steels are designed to provide an optimal balance between wear resistance, ease of implementation, and resilience.
Their resistance is enhanced through a surface hardening effect of +70 HB, resulting from local plastic deformations caused by impact with rocks or the pressure from abrasive particles. This reaction is known as the TRIP effect (Transformation Induced by Plasticity).
In mobile equipment, payload and weight are also significant concerns. Creusabro® requires thinner thicknesses for the same service life compared to conventional wear-resistant steels, thereby allowing for substantial weight savings and increased payload potential.
Creusabro 4800
Advanced wear technology.
Creusabro® 4800 stands out as an exceptionally abrasion-resistant steel, offering wear resistance surpassing conventional water-quenched 400 HB steels by 40 to 50%.
Beyond its remarkable hardness, the mechanical properties of Creusabro result from metallurgy enriched with chrome, nickel, and molybdenum, along with a specific heat treatment.
