| | | |
| | | For processing transparent melts and for large-surface plastic parts | | |
| | | |
| | | For high quality surface finishes with mould hardness 355 to 415 HB the nickel alloy steel 2711 ISO-B is recommended. For large moulds such as tailgates, mudguards, spoilers etc. with hardness values in excess of 355 HB contour hardening is preferred. The machinability of 2711 ISO-B is lower compared to 2311/2738 ISO-BM, 2738 ISO-BM and 2738mod. TS (HH) because of its low sulfur content. It may be necessary to adjust the cutting conditions, especially with deep hole drilling. | | Very good polishability Grain reliable Suitable for hard chrome plating Also suitable for high hardnesses up to 415 HB with abrasive stress | | |
| | | Characteristic profile • High sulfidic and oxidic percentage purity by using special metallurgical methods • Largely isotropic, i.e. non-directional material properties • Very good toughness and hence higher resistance to fracture | | |
