These elements impart high wear resistance and induce high hardenability to confer air-hardening properties to the steels resulting in negligible dimensional changes during hardening (i.e., non-distorting property). These steels have fair trimming, thread-rolling dies. Fig. 11.4 illustrates microstructure of one such steel.
