| 摘要 |
The invention relates to an Al-Mn-Si-N stainless acid-resisting steel substantially free of both Cr and Ni elements, which comprises the following elements: 0.0 6- 0.12 C, 4-5 Al, 16-18 Mn, 1.2-1.5 Si, 0.15-0.30 N, 0.1-0.2 Re and the balance Fe. The corrosion resistance and mechanical properties of the steel can be further improved by adding a small amount of element(s) selected from the group consisting of Cr, Ni, Co, Ti, Nb, Cu, Mo, Zr, Hf, W and the like. The stainless steel has good corrosion resistance, pressure processing charateristics and welding performance, whic h can be made into a variety of stainless steel product and can be used in a broad field.
