CORROSION AND CRACKING RESISTANT HIGH MANGANESE AUSTENITIC STEELS CONTAINING PASSIVATING ELEMENTS |
| 摘要 |
Improved steel compositions and methods of making the same are provided. The present disclosure provides advantageous corrosion and/or cracking resistant steel. More particularly, the present disclosure provides high manganese (Mn) steel compositions having enhanced corrosion and/or cracking resistance, and methods for fabricating high manganese steel compositions having enhanced corrosion and/or cracking resistance. Methods for fabricating high manganese steel compositions (e.g., via passivation) having enhanced corrosion and/or cracking resistance are also provided. |

1. A method for fabricating a ferrous based component comprising the steps of:
a. providing a composition having from 8 to 30 weight % manganese, from 11 to 30 weight % chromium, and the balance iron; b. melting the composition in a controlled environment to produce a liquid alloy steel composition; c. cooling the liquid alloy steel composition to form an alloy steel composition; d. hot deforming the alloy steel composition; e. re-heating the alloy steel composition for a pre-determined time period; f. cooling the alloy steel composition; and g. Cold deforming the alloy steel composition. |
