  • Method for the heat treatment of a manganese steel product, and manganese steel product having a special alloy
    Patent number: 11124850
    Abstract: The en-bloc heat treatment of a manganese steel product whose alloy has a carbon fraction (C) in the following range 0.02?C?0.35% by weight, and a manganese content (Mn) in the following range of 3.5% by weight?Mn?6% by weight. The en-bloc annealing method has the following substeps: heating (E1) the steel product to a first holding temperature (T1) which is in the range of 820° C.±20° C., first holding (H1) of the steel product during a first holding period (?1) at the first holding temperature (T1), faster first cooling (A1) of the steel product to a second holding temperature (T2) which is in the range between 350° C. and 450° C., second holding (H2) of the steel product during a second holding period (?2) in the range of the second holding temperature (T2), performing a slower second cooling (A2).
