Method for manufacturing and utilizing ferritic-austenitic stainless steel with high formability |
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 M 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. |
