Beschreibung
Zusammenfassung:	The invention discloses an aluminum-containing high-manganese biphase stainless steel which comprises the following components in percentage by mass: more than 0 and less than or equal to 0.06% of C, at most 0.008% of S, at most 0.01% of P, 18.0-28.0% of Cr, 18.0-30.0% of Mn, 0.5-3.0% of Ni, 1.5-2.5% of Al, 0.001-0.01% of B, 0.005-0.20% of rare earth Ce or Y, and the balance of inevitable impurities and iron. The biphase stainless steel has high strength and favorable corrosion resistance; and the biphase stainless steel has favorable hot working properties and excellent cold working properties at 850-1300 DEG C, and is low in production cost.
