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 is not easy to rust, but it is not absolutely rust-free. Stainless steel plates refer to steel plates that are resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plates refer to steel plates that are resistant to corrosion by chemically corrosive media such as acids, alkali and salts.

Stainless steel square tube is a hollow long steel material. It is called a square tube because its cross section is square. They are widely used as pipelines for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, they are lighter in weight when the bending and torsional strength are the same, so they are also widely used in the manufacture of mechanical parts and engineering structures.
