Characteristic
High strength, good machinability, medium cold deformation ability, poor weldability, no temper brittleness, low hardenability, prone to water quenching cracks, mostly used in tempered or normalized state, the two have similar comprehensive properties, surface After quenching, CK25 lost wax investment castingcan be used to manufacture parts that can withstand greater stress. It is suitable for manufacturing crankshaft spindles, drive shafts, piston rods, connecting rods, sprockets, gears, etc. It needs to be preheated before welding and slowly cooled after welding.
