DIN EN ISO 4957 40CrMnNiMo8.6.4
PRE-HARDENED MOULD STEEL WITH AN HIGH DEGREE OF THROUGH HARDENING AND MACHINABILITY
GENERAL CHARATERISTICS
LUCCHINI 2738 is the special pioneer pre-hardened alloyed steel for moulds with an high degree of through hardening, machinability and polishability. LUCCHINI 2738 has been developed for large dimension moulds with an high degree of through hardening in the section, thanks to the special calibration of the chemical analysis, particularly due to the adding up to 1.30% Nickel by alloying.
