Alloy 304 3I6 Stainless Steel Rectangular Tubing

Short Description:

Stainless steel square tube

Rectangular tube is a name for square coffin and rectangular coffin, that is, steel tubes with equal and unequal side lengths. It is made of strip steel after process treatment. Generally, the strip steel is unpacked, flattened, crimped, and welded to form a round tube, and then the round tube is rolled into a square tube and then cut to the required length.

Stainless steel rectangular tube is a kind of hollow long strip of steel with a rectangular section, so it is called a rectangular tube.

Stainless Steel Bar Surface Finish

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of stainless steel bars can have different types.

Depending on the application and desired appearance, stainless steel square tubing is available in various finishes. Some common finishes for stainless steel square tubing include:

1) Polished finish: This is a smooth, shiny finish obtained by polishing the surface of the stainless steel square tube. It is commonly used in architectural and decorative applications.

2) Brushed finish: This finish is brushed with fine abrasives on the surface of the stainless steel square tube. It creates a satin-like finish and is often used in industrial and architectural applications.

3) Satin Finish: This finish is similar to a brushed finish, but has a smoother, more even appearance. It is commonly used in architectural and decorative applications.

4) Matte: This is the matte effect obtained after removing the bright surface of the stainless steel square tube with a reducing agent. It is commonly used in industrial applications.

5) Electrolytic polishing: This is the smooth mirror effect obtained by immersing the stainless steel square tube in the electrolyte and passing an electric current. It is commonly used in pharmaceutical and food processing applications due to its cleanliness and high corrosion resistance.

Process of Production

The production process of stainless steel pipe needs to go through: stapling → calendering → annealing → slicing → pipe making → polishing
1. Tape booking: Prepare raw materials of steel tape in advance according to demand
2. Calendering: Use calendering machine to press the roll plate like rolling noodles and roll the roll plate to the required thickness.
3, annealing: due to the rolling plate after calendering, physical properties can not reach the standard, toughness is not enough, need to annealing, restore stainless steel properties.
4. Strip: According to the outer diameter of the pipe produced, strip it
5. Pipe making: Put the divided steel strip into the pipe making machine with different pipe diameter molds for production, roll it into the corresponding shape, and then weld it
6. Polishing: After the pipe is formed, the surface is polished by the polishing machine.
