Characteristic value describing the influence of the pearlite-stabilizing effect of individual trace elements on the matrix of cast iron alloys.
The pearlite stabilization of individual trace elements plays an important role, in particular in connection with the trace element score for GJS materials. The complex influence is expressed by the pearlitic influence factor Px (eq. 1).
Based on the pearlitic influence factor, eq. 2
can be used to determine the ferrite content in percent.
