LUCCHINI 4542 ESR is a stainless steel and it is it particularly suitable for the manufacture of dies and moulds subjected to high mechanical stress. LUCCHINI 4542 ESR is obtained through a special ‘super clean’ manufacturing process and by using the ESR (Electro Slag Remelting) technology which allows an excellent level of micro-purity to be achieved. LUCCHINI 4542 ESR represents the ideal option for the end user who is looking for:
• high and homogeneous mechanical characteristics throughout the whole mould regardless of its complexity;
• machinability and mirror polishability;
• micro-purity;
• resistance to corrosion.
LUCCHINI 4542 ESR quality heat treatment occurs below the phase transformation points, this process can also be carried out on a semi-finished mould, causing minimal deformation and no cracking during the hardening phase.
