Manufactured by Dörrenberg Edelstahl.
What is 1.2312 (40CrMnMoS8-6) (MCMS) Steel?
1.2312 (40CrMnMoS8-6) steel is a plastic mold steel delivered in its pre-hardened state. It is preferred when better machinability is required, as compared to 1.2311 (40CrMnMo7). 1.2312 (40CrMnMoS8-6) material is suitable for nitriding, induction hardening, and flame hardening. Due to its sulfur content, 1.2312 (40CrMnMoS8-6) plastic mold steel is not suitable for patterning.
For molds requiring uniform hardness throughout the core and products demanding better surface brightness, 1.2738 (40CrMnNiMo8-6-4) should be selected.
What is the Hardness Value of 1.2312 (40CrMnMoS8-6) (MCMS) Steel?
The hardness value of 1.2312 (40CrMnMoS8-6) steel is between 26 and 32 HRC.
What are the Mechanical Properties of 1.2312 (40CrMnMoS8-6) (MCMS) Steel?
