WE DEVELOP ADVANCED STEEL GRADES
FOR ALUMINUM PRODUCTION PROCESSES
At Lucchini RS, we are committed to innovating the aluminum production market by constantly developing customized and high-performance steel grades.
Our integrated production process allows us to control every step of the manufacturing process, ensuring that the material is designed, developed, and produced to the highest standards.
MATERIAL DESIGN
VS MATERIAL SELECTION
We believe in offering and designing materials that are tailored to meet specific requirements. We gather feedback from the in-service products, analyze durability curves and mechanical damages. Based on the findings, we design and propose the most suitable material for the intended application. This approach enables us to create customized materials that offer superior performance, durability, and strength compared to pre-selected materials.
EXTENDING LIFE OF A TWIN ROLL CASTER
Thanks to continuous study and knowledge of aluminum production processes, Lucchini RS is aware of the main mechanisms of failure and damage that can affect our products, such as abrasive and thermal wear. Our expertise enables us to design and produce increasingly high-performance materials.

THE ART OF ENGINEERING THE “PERFECT” STEEL
Lucchini RS has a dedicated team of metallurgists and engineers that designs and develops advanced steel grades, continuously upgrading their current properties. We begin by identifying the objectives that the material must fulfill, and then we work on designing a material that meets those objectives.
CASTLOS®
Castlos® family grades have been specifically developed for roll casters used in aluminium production processes. The result is a material that is highly resistant to Thermal Fatigue Cracks and can withstand even the most demanding operating conditions, delivering reliable and long-lasting performance. This is achieved through a combination of a well-balanced chemistry and an advanced production process that yield a pure, isotropic, and uniform steel grade.

FORGED IN NATURE
Lucchini RS is committed to sustainable manufacturing processes through the principles of the circular economy. We take pride in producing shells for twin roll, using sustainable methods that prioritize the health of the environment.
Sustainability is a core value of our company, and we strive to make a positive impact on the environment with every step we take.
SPECIFICALLY DESIGNED
FOR YOUR NEEDS
At Lucchini RS, we offer a wide range of steel grades specifically designed for extrusion, die casting, and hot work applications. As a fully integrated manufacturer, we can supply single components or assembled container and extrusion tooling such as die, liner, and piston, with each forged part provided at the highest level of machining precision and ready for use.
