The invention provides a stainless steel tube for a brake system of a rail vehicle and a method for producing the same. The stainless steel tube comprises the following components in weight percentage: less than 0.030 percent of C, more than 0 percent or less than 1.00 percent of Si, more than 0 percent or less than 1.50 percent of Mn, less than 0.40 percent of P, less than 0.015 percent of S, 10.5 to 12.50 percent of Cr, 0.30 to 1.00 percent of Ni, less than 0.030 percent of N, more than 0 percent or less than 0.10 percent of Cu, 6*(C+N) to 0.75 percent of Ti and Nb, and the balance of Fe and inevitable impurities. The method for producing the stainless steel tube comprises the following steps of: smelting, continuous casting, hot rolling, punching or extruding, and deep processing of the steel tube; the method is characterized in that molten iron is made into molten steel according to the components of the stainless steel tube; at the hot rolling step, the start-rolling temperature is between 1,080 and 1,150 DEG C, and the end-rolling temperature is between 850 and 900 DEG C; and the punching or extruding deformation temperature is controlled to be between 850 and 1,100 DEG C. The stainless steel tube produced by the method has the advantages of good corrosion resistance, good welding, mechanical and cold processing properties, and low price.
