Technical Card Gruppo Lucefin Revision 2013 All Rights Reserved

This document provides information on the chemical composition, heat treatment process, and material properties of an annealed tool steel. Key details include: - The steel has a carbon content between 0.43-0.48% and includes other alloying elements. - Heat treatment involves quenching at 870°C followed by tempering between 550-600°C to achieve certain mechanical properties. - The treated steel exhibits good mechanical properties at high and low temperatures, thermal shock resistance, weldability and is suitable for applications requiring these characteristics like tooling.
