304 Stainless Steel Square Tube for Construction & Industrial Use, Wholesale Supplier

1. Basic characteristics
   Material composition: 304 stainless steel square tube contains at least 18% chromium and 8% nickel. These elements form a dense oxide film on the surface of the steel, giving it excellent corrosion resistance.
   
   Appearance and structure: The appearance of the square tube is bright silver-white, the surface is smooth, and it has a high aesthetics. Its cross-sectional shape is square, which makes it have better structural stability and bearing capacity in certain specific occasions.
   
   Specification size: 304 stainless steel square tube has various specifications, and the common specification range includes square tube specifications 5×5150×150mm and thickness 0.46.0mm. The specific size can be customized according to customer needs.
   
   
2. Physical and chemical properties
   Corrosion resistance: Due to the high proportion of chromium and nickel elements, 304 stainless steel square tube has extremely strong corrosion resistance and can effectively resist the erosion of chemical substances such as acids, alkalis, and salts.
   
   High temperature resistance: The material can still maintain good mechanical properties and chemical stability under high temperature environment, and is suitable for high temperature working environment. Its working temperature range is wide, from low temperature to about 870°C (1600°F) with good performance.
   
   Mechanical properties: 304 stainless steel square tube has high strength and toughness, suitable for applications with high stress. At the same time, it has good cold processing and is easy to be processed by bending, stamping and other forming processes.
   
   
3. Processing and welding performance
   
   Processability: 304 stainless steel square tube is easy to process by cutting, bending and other processes to meet various complex engineering needs.
   
   Weldability: The material is easy to weld and is suitable for all standard welding methods, such as arc welding, gas shielded welding, etc. It is not easy to crack after welding, and the weld is beautiful and firm.
