Technological properties

---|---|---|
Application areas | For the construction of plastic molds with superior surface requirements on molds. | |
Chemical composition | Nickel, Vanadium alloyed depending on dimension. | |
Delivery condtion | DIMO 2311 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 2311 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 2311 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 2311 production route is designed to achieve the excellent properties of this mold steel type with superior surface requirements. DIMO 2311 is characterized by high dimensional stability. The DIMO 2311 production route provides excellent polishability, photoetchability and spark erosion properties. Therefore DIMO 2311 is particularly suitable for molds with superior surface requirements if suitable manufacturing processes are employed. The good sulfidic and oxidic cleanliness and the modification of the few remaining inclusions by the calcium treatment lead to good machinability and minimize the tool wear. These properties can only be achieved by the combination of the following DIMO 2311-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: |
