alloy steel that is passive, corrosion resistant and rust free in atmosphere and corrosive media such as acid, alkali and salt. In a narrow sense, stainless steel refers to steel that is not easy to rust in weak corrosive media such as atmosphere, steam and water, while the commonly said stainless steel refers to steel that is resistant to corrosion but not rusty in acid, alkali, salt and other media under specific conditions, that is, stainless acid resistant steel. stainless steel has excellent corrosion resistance, formability, appearance decoration and appropriate strength and toughness in a wide temperature range, so it is widely used in petrochemical, light industry, food, household appliances, construction and other fields. At present, the output of stainless steel has exceeded 4% of the total steel output, and the growth rate is significantly greater than the growth rate of the total steel output.
