40CrMnMoS 8-6 / AISI: P20+S
Delivery Method : Hardened and tempered 280-325 HB
Uses : It can be used as a core in plastic mold applications where brightness and surface quality are not sensitive. Widely used as Mold holder in plastic and metal injection mold systems. The sulfur element in its content provides easy processability to the material. It is not suitable for patterning, primarily through acid.
*Time interval varying depending on the section.
