Strict environmental
requirements

Environmental constraints are taken into account from the very first stage, starting with raw material sourcing. Ascodunes ensures regulatory compliance while continuously optimizing its processes to reduce environmental impact.

This approach is fully aligned with a sustainable industrial performance strategy.

Comprehensive cost
control

Each product is developed in strict compliance with technical specifications, with high standards in terms of quality, traceability, and regulatory compliance. Controlled processes and rigorous inspections ensure reliable, repeatable products suited to the most demanding industrial environments.

Ascodunes is also committed to comprehensive cost control, by simplifying technical processes, reducing energy consumption, and optimizing industrial flows. This approach improves productivity, secures lead times, and enhances project competitiveness—without compromising quality.

Meeting deadlines is a top priority, supported by a commercial team working in direct coordination with production. This organization ensures optimal cost control and a high level of service.

Steel grades and specialties

Ascodunes masters the transformation of a wide range of steel grades, including both standard and high value-added specialty grades developed to meet demanding industrial applications.

Standard grades processed by Ascodunes include carbon steels, low-alloy steels, and alloy steels, as well as steels designed for heat treatment, carburizing, induction hardening, bearing applications, and nitriding. These grades comply with current European and international standards and are used across a wide range of industrial applications.

Ascodunes also offers recognized expertise in specialty grades, engineered to optimize mechanical performance, in-service durability, and component reliability.

This dual expertise enables Ascodunes to meet complex technical specifications, including high requirements in terms of inclusion cleanliness, metallurgical quality, mechanical performance, and industrial repeatability.

Our industries

Mechanical engineering
Mechanical engineering is a major application field for Ascodunes, particularly for the supply of steel products intended for highly stressed components, large dimensions, and demanding metallurgical requirements.

Steel processed at the Dunes site is used in the manufacturing of tool holders, camshafts, hammer bodies, gears, machine tools, screws, high-pressure tubes, and extrusion rolls, as well as more specific applications such as ammunition and barrels, and heavy mechanical components including gearboxes, slewing rings, pistons, crankshafts, axles, and shafts.

These applications require high material homogeneity, controlled inclusion cleanliness, excellent heat treatment capability, and full compatibility with machining operations.

Ascodunes’ expertise is based on full control of the Dunes industrial chain, integrating hot rolling, heat treatment, finishing, and inspection processes, ensuring compliance with technical specifications and reliability in service.

Bearings
Bearing applications require extremely high standards in terms of metallurgical quality, fatigue resistance, and performance stability in service.

Ascodunes provides steels specifically designed to meet these constraints, supported by rigorous control of transformation and inspection processes.

Standard steels for bearing applications include through-hardened steels, carburizing and carbonitriding steels, as well as carbon steels for surface hardening. These grades are selected for their suitability for heat treatment and compatibility with bearing component manufacturing processes.

Steels used in bearing applications offer excellent fatigue resistance, high endurance under Hertzian contact stress, and strong resistance to elevated temperatures. The low dispersion of fatigue performance results enables more precise component design, contributing to the reliability and lifespan of bearing systems.

This expertise is supported by full control of the industrial chain, including carefully selected raw materials sourced from recognized steel producers.

Oil & Gas
Oil and gas applications—particularly offshore drilling—impose extreme constraints in terms of mechanical strength, fatigue resistance, impact resistance, and reliability under severe operating conditions.

Our steel products are used in the manufacturing of key components for drilling and completion systems, including drill collars, tool joints, HWDP (Heavy Weight Drill Pipe), jars, stabilizers, packers, and reamer mandrels. These components are subjected to high levels of tension, torsion, and bending, as well as significant cyclic loading.

Ascodunes provides standard steel grades selected for their suitability for heat treatment and compliance with industry standards. In addition, the company develops and processes specific grades engineered to meet enhanced requirements in terms of mechanical performance, metallurgical cleanliness, and consistency.

These steels offer excellent fatigue resistance, high strength under combined stresses, and stable mechanical properties—even under severe service conditions. Tight control of performance variability ensures reliable component design and improved operational durability.
