IiMfuneko zezinto eziphathekayo
Imathiriyeli yediskhi yebhuleki ithatha umgangatho welizwe lam wentsimbi engwevu engama-250, ekubhekiswa kuyo njenge-HT250, elingana nomgangatho we-G3000 waseMelika. Iimfuno zezinto ezintathu eziphambili zokwakheka kweekhemikhali zezi: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9. Iimfuno zokusebenza koomatshini: amandla okuqina>=206MPa, amandla okugoba>=1000MPa, ukunxaxha>=5.1mm, iimfuno zokuqina phakathi: 187∽241HBS.
