DIN C30E/Ck30 steel structure,C30E/Ck30 steel structure Manufacturer

DIN C30E/Ck30 steel structure is a kind of super heavy steel for mould. The maximum thickness of CK30 we offer can reach as much as 600 mm .CK30 is a higher carbon (0.30%) manganese steel in the plain carbon steel alloy family. CK30 provides greater strength than the lower carbon grades while still retaining reasonable ductility.
