| Application areas | It is used by the customers for accessories with holder block requirements as e.g. ejector plates, supports, clamping plates and housings for diecasting dies. | |
| Chemical composition | Nickel, Vanadium alloyed depending on dimension. | |
| Delivery condtion | DIMO 2312 is supplied in the hardened (air hardened + tempered) condition. | |
| General note | If special requirements, which are not listed in this specification, are to be met by the steel due to its intended use or processing, these requirements are to be agreed before placing the order. The information in this specification is a product description. This specification is updated if necessary. The latest version is available from the mill or as download at www.dillinger.de. | |
| Heat Treatment | DIMO 2312 is delivered in the hardened condition; therefore further heat treatment is generally not necessary. This avoids the risks and costs involved by the hardening and tempering of a mold after processing. Should a heat treatment become necessary, recommended data can be found in material data sheet at www.dillinger.de. | |
| Other | DIMO 2312 is available as plate with cut edges (sheared, flame cut or water jet cut) in the following dimensions: Widths < 1250 mm (49 in) have to be ordered with an even number of plates, Other dimensions available upon request. | |
| Processing history | The DIMO 2312 production route is designed to achieve the excellent machinability and dimensional stability of this holderblock steel type. The high oxidic cleanliness and the large number of sulfides provide excellent machinability and low tool wear. On flame cut edges, a surplus of 10 mm for the machining has to be scheduled. DIMO 2312 should only be applied for molds if the surface requirements referring to e.g. polishability and photoetchability are less ambitious. DIMO 2312 should not be applied for spark erosion. The above mentionned properties can only be achieved by the combination of the following DIMO 2312-production steps: | |
| Surface condition | Surface quality: Unless otherwise agreed, the specifications will be in accordance with EN 10163-2 class A, subclass 3. Shot blasting of upper and lower surface of the plate and shop priming are possible on request. | |
| Testings | Unless otherwise agreed, the results are documented in an inspection certificate 3.1 in accordance with EN 10204. | |
| Tolerances | Unless otherwise agreed, tolerances are in accordance with EN 10029, with the following restrictions: | |
