The combustion pre-chambers for indirect injection diesel engines are produced from bar or precision casting of CR-MO steel specially designed for this type of use.

The main feature of this special steel is to allow, after fixing the pre-chambers in the head, an excellent machinability to the tool of the allowances on the flange while maintaining high hardness and heat resistance values.

The vast range, constantly updated, includes almost all diesel cars circulating in Europe including those of Japanese manufacture.
