Performance requirements and corrosion resistance of stainless

  • Today, Huiyingsteel, a professional stainless steel sheet manufacturer in China, will introduce some basic knowledge of stainless steel sheets. The article will briefly introduce the performance requirements and corrosion resistance of stainless steel sheets.

    Overview of Stainless Steel Sheets

    Stainless steel plate, high strength, and hardness, good plasticity, and toughness. According to the method of production, it is divided into two types: hot rolling and cold rolling, and it is divided into 5 categories according to the structural characteristics of the steel. The stainless steel sheet industry network is divided into 200-series, 300-series, and 400-series stainless steel products.

    Stainless steel sheet performance requirements

    It is required to withstand the corrosion of various acids such as oxalic acid, sulfuric acid-ferric sulfate, nitric acid, nitric acid-hydrofluoric acid, sulfuric acid-copper sulfate, phosphoric acid, formic acid, acetic acid, etc. It is widely used in the chemical industry, food, medicine, papermaking, petroleum, atomic energy, etc. Industry, as well as various parts and components of construction, kitchenware, tableware, vehicles, and household appliances. 

    304 Hot Rolled Stainless Steel Plate

    In order to ensure that the mechanical properties such as yield strength, tensile strength, elongation, and hardness of various stainless steel plates meet the requirements, the steel plates must be subjected to heat treatment such as annealing, solution treatment, and aging treatment before delivery.

    The stainless steel plate has a smooth surface, high plasticity, toughness, and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions, and other media. It is an alloy steel that does not rust easily but is not absolutely rust-free.

    The corrosion resistance of stainless steel sheets

    The corrosion resistance of stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal structure, and the main role is chromium. Chromium has high chemical stability and can form a passivation film on the surface of stainless steel plate, which isolates the metal from the outside world, protects the stainless steel plate from oxidation, and increases the corrosion resistance of the steel plate. After the passive film is destroyed, the corrosion resistance of the stainless steel sheet decreases.

    The above is the whole content of the stainless steel sheet brought to you by Huiying'steel today. I hope this article can help you get a preliminary understanding of stainless steel sheets. For more stainless steel-related information, please click our previous articles to view:
