Industeel CLC 1.2311 Prehardened Mold Steel (300HB/30HRC)
Categories:	Metal; Ferrous Metal; Carbon Steel; High Carbon Steel; Tool Steel; Mold Steel
Material Notes:	Description: CLC 1.2311 is a 300HB (30HRC) pre-hardened grade specially designed for plastic mold industry. Chromium, Molybdenum, carbon and manganese additions are optimized to have a fully martensite-bainite microstructure after quenching. The steel is melted in electrical furnace and refined with VOD or DH device The cleanliness of the steel is guaranteed as well as the soundness. This makes the steel particularly well adapted for mold steel even when polishing or chemical etching are required for surface finish quality. Information provided by manufacturer.
Key Words:	AFNOR 40CMD8, DIN 40CrMnMo7, WERKSTOFF.Nbr 1.2311, AISI P20
