The crusher jaw had therefore failed prematurely. ASTM A 128 grade B-4 is a grade of austenitic manganese steels that combines both high toughness and good wear-resistant properties required for crusher jaws. From the spectrometric analysis, the elemental composition of the failed crusher jaw conforms to ASTM A 128 grade B-4.
