When it comes to annealing for thick sheets and special steels, Sidertaglio Lamiere’s thermal stress-relieving process stands out for its precision and impact. This specialized treatment not only removes internal stresses but also optimizes the mechanical properties of the thick sheets, making them highly durable and ideal for demanding applications. Sidertaglio Lamiere’s attention to detail ensures that every sheet is meticulously prepared to withstand extreme conditions.

Stress-relieving annealing is a careful and multi-step procedure. It begins with heating the sheet, followed by a holding phase, and concludes with controlled cooling. Each phase is critical for eliminating over 90% of internal stresses and ensuring the integrity of the material. This process also makes the sheets more workable and helps avoid deformation during future machining operations.

Sidertaglio Lamiere’s process of annealing for thick sheets plays a key role in enhancing the precision and reliability of materials. By treating thick sheets, the risks of deformation and cracking are significantly reduced, while machinability is improved, extending tool life and reducing costs for subsequent processes.

• Minimized Internal Stresses: The treatment eliminates more than 90% of internal stresses, making the material stable for further processing.
• Improved Machinability: Treated sheets become more malleable, reducing tool wear and extending tool life.
• Reduced Risk of Cracking: The internal structure is optimized, minimizing the risk of fractures during use.
• Enhanced Precision: Machined dimensions are more accurate, contributing to higher quality in final products.
• Time Efficiency: The reduced need for oversize margins results in shorter machining times, accelerating delivery to customers.

The annealing temperature must be tailored to the specific material. For quenched and tempered steels, the annealing process requires temperatures at least 30°C lower than the last tempering temperature. This careful control ensures that the steel’s properties are preserved. Sidertaglio Lamiere’s expertise lies in adapting annealing for thick sheets to suit each type of steel, ensuring maximum effectiveness and quality.

While the stress-relieving annealing process is beneficial, it does come with certain cost and time considerations. The entire process—from heating to cooling—can take several hours, requiring meticulous planning. Additionally, energy consumption and furnace maintenance are important factors to account for. Despite these challenges, the long-term benefits of this treatment make it a wise investment in ensuring the quality and durability of thick sheet metal.
