The 201 Square Tube is made from 201 stainless steel, known for its excellent corrosion resistance and strength. Available in various sizes, it features smooth surfaces for easy installation.

This tube is widely used in architectural decoration, kitchenware, and industrial applications, including automotive exhausts and chemical processing. Its durability allows it to withstand external forces, while its ease of processing enables users to customize it for specific needs.

The 201 Square Tube combines functionality with a modern aesthetic.

201 Stainless Steel Square Tube

1. Material and composition
   
   201 square tube is mainly made of 201 stainless steel, and its chemical composition includes carbon (C), silicon (Si), manganese (Mn), chromium (Cr), nitrogen (N), phosphorus (P), sulfur (S) and nickel (Ni).
   
   Among them, the chromium content is relatively high, usually between 15% and 17%, which gives 201 stainless steel good corrosion resistance. Although the nickel content is low, generally between 4% and 6%, this also makes 201 stainless steel have a lower cost while maintaining a certain corrosion resistance.
   
   
2. Specifications and sizes
   
   201 square tubes have various specifications, including but not limited to 35×35×2.2, 38×38×1.0 to 4.0 and other sizes. These square tubes have smooth inner and outer walls, precise dimensions and good consistency, which facilitates customers to accurately dock and install in subsequent processing and use.
   
   
3. Performance characteristics
   
   a. Corrosion resistance: 201 stainless steel square tube has good acid and alkali resistance, and can remain stable in a variety of corrosive environments.
   b. High strength: 201 square tube has high tensile strength and yield strength, and can withstand large external forces without breaking easily.
   c. Easy to process: 201 square tube is easy to process by cutting, bending, punching and other processes to meet various complex engineering needs.
   d. Beautiful and elegant: 201 square tube has a modern feel, can enhance the beauty of the space, and is suitable for a variety of decorative occasions.
   
   
4. Production process
   
   The production process of 201 square tube includes curling and forming of steel plate or steel strip, and after welding, it is placed in a hot-dip galvanizing pool for a series of chemical reactions to form a square tube.
   
   This process is simple, with high production efficiency and a variety of varieties, which is suitable for small stainless steel square tube manufacturers.
