| titleOfInvention | A new type of high-silicon and high-chromium high-manganese steel and preparation method thereof |
| abstract | The invention discloses a novel high-chromium, high-silicon and high-manganese steel and a preparation method thereof. The weight percentages of the chemical components of the high-manganese steel are: C: 0.4-1.1%, Mn: 13-20%, Cr: 3- 7%, Si: 2～4%, S≤0.04%, P≤0.03%, Mo: 0.5‑0.9%, V: 0.1‑0.2%, Ti: 0.08‑0.15%, Cu: 0.2‑ 0.6%, the rest is Fe. In the novel high manganese steel of the present invention, Si-Ca alloy is added in the pouring process after smelting: 0.25-0.4%. The heat treatment process of the casting is as follows: the solution treatment temperature is 1080-1180°C, the workpiece is released after the heat preservation is completed, and when the surface temperature of the workpiece is 1020-1050°C, it is immediately water-cooled until the temperature of the casting is room temperature-120°C, and the water is discharged, and then the workpiece is placed in Hold in a resistance furnace at 200-230°C for 3-5 hours. High-manganese steel has single-phase austenite, close-packed hexagonal martensite (ε-martensite) and austenite complex structure after heat treatment, and a small amount of body-centered cubic martensite (α'-martensite) may also exist. body). The mechanical properties are as follows: the yield strength is 460-600MPa, the tensile strength is 980-1100MPa, and the U-notch impact toughness is 162-320J/cm 2 . |
