Grade 201 is an austenitic chromiumnickel-manganese stainless steel that was developed originally to conserve nickel. In the 201 steel composition, manganese and nitrogen are partially substituted for nickel.It provides properties similar to Type 301 and can be used in most applications for Type 301.
SUS201 stainless steel is a low-cost austenitic stainless steel that belongs to the 200 series stainless steels. It is similar in composition to the more common grade, AISI 304 stainless steel, but with a slightly lower nickel content and higher manganese content.Stainless 201 can be used in many applications because of its wide range of mechanical properties in the annealed and cold worked condition. Grade 201steel is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.
201 Stainless Steel Pipe contains stainless steel welded pipe and stainless steel seamless pipe.SUS201 stainless steel pipes are commonly used in various applications such as construction, automotive, kitchenware, and decorative purposes. They offer good corrosion resistance, high formability, and low maintenance requirements. However, compared to higher-grade stainless steels like AISI 304 or 316, SUS201 has lower corrosion resistance and may be more prone to surface rusting in certain environments.

SUS201 Stainless Pipes Features
- One of the important features of 201 stainless steel tube is that it has a relatively high strength-to-weight ratio, which makes it both durable and lightweight. This makes it an excellent choice for applications that require high-performance piping, such as in the aerospace and automotive industries.
- Another important feature of 201 stainless steel tube is that it can be easily welded and cut to size, which means that it is easy to work with and can be customized to suit specific needs. This makes it an ideal choice for use in a range of applications, from plumbing and HVAC systems to industrial equipment and machinery.
- In addition to its high resistance to corrosion and heat, 201 stainless steel tube is also highly resistant to water and other types of liquids, making it an excellent choice for use in piping systems that are designed to handle high volumes of fluids.
