MA-Rekord (1.2758) Steel

Steel name: MA-Rekord (1.2758)
Diagram No.: 2515
Mat.No. (Wr.Nr.) designation: 1.2758
DIN designation: X50WNiCrVCo12-12
Chemical composition in weight %: 0.51% C, 1.40% Si, 0.70% Mn, 4.00% Cr, 0.60% Mo, 11.50% Ni, 1.10% V, 1.50% Co, 12.00% W
Steel group: Hot work tool steels
Properties: MA-Rekord is a high-alloy hot-work tool steel with an austenitic structure. By forging and subsequent precipitation hardening at approx. 800 °C or by a special heat treatment, the operational strength of 1350 - 1550 MPa is achieved.
Applications: Extrusion dies for processing hard-to-press non-ferrous metals and steel in the manufacture of wire, rods, pipes, strips and simple profiles.
Reference: Not shown in this demo version.

Heat Treatment
Preheating before use: Temperature 400 - 600 °C, essential, avoid cooling during press operation.
Cooling after use: Immediately after the last pressing, slowly from 500 - 600 °C in the furnace.
