PRECIPITATION HARDENING MARTENSITIC STAINLESS STEEL: A INNOVATIVE APPROACH TO CORROSION RESISTANT PLASTIC INDUSTRY
GENERAL CHARATERISTICS
LUCCHINI 4542 is a stainless steel and it is it particularly suitable for the manufacture of dies and moulds subjected to high mechanical stress. LUCCHINI 4542 is obtained through a special ‘super clean’ manufacturing process, which allows an excellent level of micro-purity to be achieved. LUCCHINI 4542 is adaptable to a wide range of applications, much more so than those obtained through other grades that are normally used in this field; LUCCHINI 4542 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;
• resistance to corrosion.
LUCCHINI 4542 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.
