About Austenitic Stainless Steel

Austenitic stainless steels are classified in the 200 and 300 series, with 16% to 30% chromium and 2% to 20% nickel for enhanced surface quality, formability, increased corrosion and wear resistance. The austenitic stainless steels are more easily recognized because of their non magnetic properties. Depending on the composition, some austenitics do become somewhat magnetic when cold worked. While austenitic steels are more expensive than ferritic stainless steel. Austenitic stainless steels are non-hardenable by heat treating.

What is 200 and 300 series Austenitic Stainless Steel Tubes?

200 Series Stainless Steels

Stainless steels with a low nickel and high nitrogen content are classified as 200 series. These are chromium-nickel-manganese austenitic stainless steels. Grade 201 is hardenable through cold working while the grade 202 is a general purpose stainless steel. Decreasing nickel content and increasing manganese results in weak corrosion resistance.

300 Series Stainless Steels

The most common austenitic stainless steels are iron-chromium-nickel steels and are widely known as the 300 series. In this series the most widely used austenitic stainless steel is the grade 304, also known as 18/8 for its composition of 18 % chromium and 8 % nickel.  The second most common austenitic stainless steel in this series is the grade 316, also called marine grade stainless steel, used primarily for its increased resistance to corrosion. A typical composition of 18 % chromium and 10 % nickel, commonly known as 18/10 stainless, is often used in cutlery and high quality cookware.

Features of Austenitic Stainless Steel Tubes

Corrosion Resistance

Corrosion resistance in stainless steels is primarily determined by chromium content. Austenitic stainless steels, as a class, have excellent corrosion resistance and those with molybdenum additions have improved pitting resistance. The nickel content in austenitic stainless steels helps to reduce the rate of corrosion, particularly in acid environments. Austenitic grades, however, are susceptible to chloride stress corrosion cracking (SCC) and are not recommended for service that combines tensile stress and the presence of chlorides, even at moderate temperatures. Higher carbon austenitic grades can be susceptible to intergranular corrosion after certain high temperature exposures, including welding. For applications that require welding, a post-weld heat treatment or selection of a low carbon or stabilized grade such as Type 304L, 316L and 321, is recommended.

Formability

Austenitic stainless steels are generally considered to have excellent formability. Lean austenitic grades, including NITRONIC 30, Type 201, and Type 301, have high work hardening rates and resistance to thinning which results in improved stretch formability. For deep drawing, it is generally advised to use higher nickel content, lower work hardening grades such as Types 304 or 305.

Weldability

Austenitic stainless steels exhibit similar welding characteristics. These alloys can be joined by shielded fusion and resistance welding processes. Good mechanical strength is developed in welded joints without the necessity of preheating or post-weld annealing. Heat treatment or alternative selection of a low-carbon grade is advised to prevent corrosion in the weld area. The physical properties of austenitic stainless steels must be taken into consideration when developing appropriate welding practices.

Temperature

In service conditions with extreme temperatures, either cryogenic or elevated, austenitic stainless steels are well suited. Some austenitic grades retain good ductility and impact strength at sub-zero temperatures. These alloys also maintain tensile and creep strength at elevated temperatures.

Applications of Austenitic Stainless Steel Tubes

Some of the applications for austenitic stainless steel tubes:

  • Kitchen sinks
