Ibisabwa
Ibikoresho bya disiki ya feri bifata igihugu cyanjye cyumuhondo wicyuma 250 cyiswe HT250, gihwanye na Amerika G3000.Ibisabwa kubintu bitatu byingenzi bigize imiti ni: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9.Imikorere ya mashini isabwa: imbaraga zingana> = 206MPa, imbaraga zunama> = 1000MPa, gutandukana> = 5.1mm, ibisabwa bikomeye hagati ya: 187∽241HBS.
