Shuruudaha Agabka
Walaxda saxanka biriiga waxa ay qabataa heerka 250 kabka cawlan ee dalkayga, oo loo yaqaan HT250, kaas oo u dhigma heerka American G3000. Shuruudaha saddexda walxood ee ugu muhiimsan ee ka kooban kiimikada waa: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9. Shuruudaha waxqabadka makaanikada: xoogga xajinta>= 206MPa, xoog laabashada>= 1000MPa, leexin>=5.1mm, shuruudaha qalafsanaanta u dhexeeya: 187∽241HBS.
