304 Stainless Steel Sheet is widely used for its excellent performance and has become a popular material in the market. Today, I will analyze the problems that are prone to occur when cutting 304 Stainless Steel Sheet.

Apply pickling paste or spray to assist the rusted areas of the Stainless Steel Coil in repassivating, forming a chromium oxide film to restore its corrosion resistance.

Ferritic Stainless Steel Tube. Contains 12% to 30% chromium. Its corrosion resistance, toughness, and weldability improve with increasing chromium content, and it exhibits good resistance to chloride stress corrosion. Austenitic Stainless Steel Tube. Contains more than 18% chromium, along with about 8% nickel and small amounts of molybdenum, titanium, nitrogen, and other elements. It offers comprehensive performance and can resist corrosion from various media.

Stainless Steel uses iron as its base material, and the addition of alloying elements endows Stainless Steel with corrosion resistance at both room temperature and high temperatures, as well as general physical properties similar to common materials.

If there is rust and dirt on the inner surface of the Stainless Steel Tube, a circular wire brush and cloth strips can be tied to thick iron wire or thin steel rope, and pulled back and forth through the tube (for large-diameter fittings, a winch can also be used for dragging back and forth). Then, steam or water is introduced for rinsing, followed by drying the tube with compressed air or an exhaust fan. After this, degreasing can be performed.

There are several reasons for the formation of pores on the surface of 310S Stainless Steel Sheet. For example, if the base material has high carbon, sulfur, or silicon content, pores are likely to occur. The solution is either to replace the base material or to use electrodes with a low-hydrogen slag system.
