Description Round stainless steel pipe made of AISI 201 steel

Characteristics of AISI 201 pipe

AISI 201 steel has high corrosion resistance and low cost.

The pipe is made from metal strip. First, the workpiece is formed on a rolling machine, then the longitudinal seam is welded. AISI 201 steel is an austenitic alloy based on chromium and nickel. Unlike similar alloys, AISI 201 has a lower price - 30-50% less than the cost of AISI 321. This difference is obtained with a lower concentration of nickel in the alloy. The alloy is alloyed with nitrogen and manganese.

Stainless steel pipes AISI 201

Sunning Steel Limited offers a wide range of stainless steel pipes made of AISI 201 steel. This grade has an austenitic structure and is resistant to corrosion. Its composition has reduced nickel content due to the addition of manganese. In terms of its characteristics, it is similar to AISI 304 stainless steel. AISI 201 pipes are used in construction, architecture, for the installation of welded structures, canopies, fences, as well as in the food industry.


The chemical composition of AISI 201 steel provides the following pipe features:

High strength. The products can withstand fairly strong water hammers and resist external deforming loads (for example, soil pressure during underground installation).

Wear resistance. AISI 201 steel pipes can be used to transport media containing solids.

Heat resistance. The product can withstand heating up to +760 °C.

Weather resistant. Rolled steel does not corrode upon contact with oxygen in the air, sea water, or precipitation.

Chemical resistance. AISI 201 steel pipes are resistant to moderately aggressive acidic environments.

Plastic. The products can be easily forged, arc welded, and cold machined.


  1. High mechanical strength
    Pipes are resistant to various shock and deformation loads and wear, durable and practically do not lose their quality over time.
  2. Corrosion resistance
    Stainless steel pipes do not oxidize under the influence of moisture and aggressive environments. They are chemically inert and do not interact with liquids and gases.
  3. Resistance to changes in temperature and humidity
    Pipes are little susceptible to changes in linear dimensions when temperatures change and do not respond to changes in humidity and pressure, which allows them to be used in the most severe conditions.
  4. High ductility
    Stainless steel pipes are easy to process because they are ductile and not brittle, which allows them to be bent at the desired angles and given the desired shape.
  5. Aesthetic appearance
    Stainless steel looks great even without additional processing - painting or polishing.

Scope of application of welded pipes

Reliable and relatively lightweight welded stainless steel pipes are used for assembling heat exchangers and heaters, when laying utilities and pipelines in enterprises:

chemical and oil refining industries;

mechanical engineering and shipbuilding;

food sector.

Rectangular pipes can act as the basis of many metal structures. Rectangular rolled products are used to install fences and railings, load-bearing structures, furniture frames and vehicle elements. The advantages of such products are low weight and high strength. Manufactured from steel grades AISI 201, 304, 430.

Square pipes can withstand high loads, so they are installed as a reinforcing element in metal structures. Most often, square pipes are used when installing the frame of a structure or assembling a structure for a car body. Manufactured from steel grades AISI 430, 304.

Round pipes are the most common. They are widely used in pipelines for transporting liquids and gases under high pressure. The products are used in food, chemical, oil and other industries. We offer structural and special-purpose pipes. Manufactured from steel grades AISI 304, 316, 201.

Oval pipes have increased strength and a mirror surface compared to round products. Due to this, they are used as decorative elements in metal structures in furniture production and mechanical engineering. Manufactured from steel grades AISI 304, 316, 201.
