高成形性を有するフェライト・オーステナイト系ステンレス鋼の製造および利用方法 |
摘要 |
The invention relates to a method for manufacturing a ferritic-austenitic stainless steel having good formability and high elongation. The stainless steel is heat treated so that the microstructure of the stainless steel contains 45-75% austenite in the heat treated condition, the remaining microstructure being ferrite, and the measured Md30 temperature of the stainless steel is adjusted between 0 and 50° C. in order to utilize the transformation induced plasticity (TRIP) for improving the formability of the stainless steel. |
