Mahimmancin ƙarfin ƙarfin hali yana kusan 30-50mm cikin ruwa da 16-32mm a cikin mai. Tana da hankali ga shayar da dabi'ar dabbobi don jin zafi yayin magani mai zafi, kuma yana yiwuwa ne ga fatattaka lokacin ruwa. An yi amfani da Oil Quenching. Water quenching is suitable for section sizes greater than 80. Oil cooling: After annealing, the cutting ability is good, but the cold deformation plasticity is low, and the welding performance is poor. Wannan karfe an yi amfani dashi gaba daya bayan saukar da kai da zafin rana a zazzabi matsakaici. 3-16
