The invention discloses a method for producing stainless steel by using stainless steel scraps. The method comprises the following steps that 1, the cleaned stainless steel scraps are pressed to prepare stainless steel scrap pressing blocks; 2, cutting risers and casting systems for producing the previous batch of stainless steel and the stainless steel chip pressing blocks are put into an intermediate frequency furnace for melting operation, and chemical component analysis is made on an analysis sample before the furnace; 3, according to the analysis result of the chemical components, by combining the weight percentage of the chemical components of the stainless steel product, lacked single element metal is added into the intermediate frequency furnace; 4, after the component adjustment is completed, and the temperature of the molten steel reaches the target required temperature, the molten steel is discharged from the furnace to pour a casting or a steel billet. According to the method for producing the stainless steel, the consumption of noble metal elements such as nickel, chromium and molybdenum in the stainless steel scrap smelting process is greatly reduced, and the waste ofstainless steel resources is reduced.
