NOVELTY - Anti-rust and anti-corrosion low-nickel stainless steel material comprises 24-26 wt.% chromium, 8-10 wt.% boron, 5.5-6.8 wt.% manganese, 3.5-3.8 wt.% molybdenum, 0.5-1.5 wt.% nickel, 0.5-0.6 wt.% vanadium, 0.01-0.03 wt.% phosphorus, 0.2-0.8 wt.% silicon, 0.35-0.4 wt.% nitrogen, 0.03-0.05 wt.% carbon, 0.02-0.06 wt.% rare earth selenium, 0.04-0.06 wt.% rare earth element lanthanum, 0.1-0.3 wt.% stabilizer and remainder is iron. USE - Anti-rust and anti-corrosion low-nickel stainless steel material. ADVANTAGE - The anti-rust and anti-corrosion low-nickel stainless steel material has uniform texture, good corrosion resistance, simple preparation method and can increase a large amount of nitrogen elements, has excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance, and has excellent rust and corrosion resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for stainless steel alloy, which involves putting each raw material in a melting furnace, and after sealing, extracting the air in the melting furnace into a vacuum state, and starting to heat up and melt, introducing nitrogen from the bottom of the melting furnace and keep stirring when all the raw materials are in a molten state for a period of time, continue to seal the melting furnace, and opening the vent of the melting furnace after the internal air pressure increases to a certain level, slowly release the pressure, keeping a nitrogen atmosphere in the smelting furnace and a certain constant pressure state, and stopping the introduction of nitrogen, pouring the melt obtained into a mold for cooling and molding to obtain a semi-finished stainless steel alloy, placing semi-finished stainless steel alloy in a melting furnace, sealing and evacuating, heating up to 1100-1400 degrees C for a period of time, passing ammonia gas and closing the gas outlet, increasing pressure in the smelting furnace, so that the ammonia gas reacts with the surface of the semi-finished stainless steel alloy under high temperature and high pressure to produce iron nitride, forging stainless steel alloy at elevated temperature, putting stainless steel alloy into the protective liquid and then heating and baking to form a protective film to obtain the finished stainless steel alloy; and (2) a method for anti-rust and anti-corrosion low-nickel stainless steel material, which involves mixing protective liquid includes 4-6 pts. wt. polyoxyethylene castor oil, 2-6 pts. wt. glycerol, 0.5-1 pts. wt. sodium benzoate, 3-5 pts. wt. phosphoric acid, 1-2 pts. wt. rosin amine, 0.5-1 pts. wt. disodium ethylenediaminetetraacetic acid (EDTA) , 0.1-0.2 pts. wt. nano calcium carbonate, 0.1-0.5 pts. wt. sodium carboxymethyl cellulose, 0.01-0.1 pts. wt. polyoxyethylene sorbitan monooleate, 250 pts. wt. water, mixing the raw materials, stirring and heating to 70-80 degrees C, stirring and reacting for 3-5 hours to obtain final product.
