Stainless steel plates have a smooth surface, high plasticity, toughness, and mechanical strength, and are resistant to corrosion from acid, alkaline gases, solutions, and other media. It is an alloy steel that is not easily rusted, but it is not rust free. Stainless steel plate refers to steel plates that are resistant to weak media such as atmosphere, steam, and water corrosion, while acid resistant steel plate refers to steel plates that are resistant to chemical corrosive media such as acid, alkali, and salt corrosion.Stainless steel plates have the ability to resist general corrosion similar to unstable nickel chromium alloy 304. Long term heating in the temperature range of chromium carbide may affect the performance of alloys 321 and 347 in harsh corrosive media. Mainly used for high-temperature applications, which require materials to have strong anti sensitization properties to prevent intergranular corrosion at lower temperatures.
