CK25 is a kind of super heavy steel for mould.The maximum thickness of CK25 we offer can reach as much as 600 mm.CK25 is also a kind of common carbon steel.With professional production experience,strict control CK25 chemical composition and CK25 mechanical properties.
CK25 is low alloy steel characterized by high tensile strength.finished goods condition: hot forging/hot rolling + annealing/normalizing + tempering/quenching + tempering/any conditions based on the customer's requirement
Surface conditions:scaled (hot working finish)/ground/rough machining/fine machining/based on the customer's requirement.
