Steel 1.2316 - CMR
1.2316 - CMR steel:
heat-treatable corrosion-resistant steels.
What?
1.2316 – CMR steel belongs to the group of heat-treatable corrosion-resistant steels. This resistance against corrosion is achieved through the high Cr and low C content. CMR is suitable for the processing of chemically particularly aggressive plastics such as PVC. Chrome-plating is unneccessary. CMR has a good polishability. Delivery condition: Tempered, strength as required between 800 and 1100 MPa.

Heat treatment
Hardening | Temperature: 1020 – 1050 °C |
---|---|
Koeling: interrupt oil cooling at 250 °C | |
Tempering | Temperatuur: 580 – 620 °C Avoid temperature range of the secondary hardness maximum. |
Hardness: see tempering curve | |
Nitriding | Possible, temper correspondingly. The corrosion resistance is reduced by such a treatment. |
