How good is 201 stainless steel?

A low-nickel stainless steel

201 stainless steel is currently the cheapest type of cold-rolled stainless steel on the market. By replacing nickel with elements such as manganese and nitrogen, 200 series austenitic stainless steels were developed.

For example, the chromium content of 201 stainless steel is 16-18 and the nickel content is only 0.3-1.2. The expensive chromium and nickel are replaced by cheap elements such as manganese and nitrogen. In addition, the production cost of 201 stainless steel is cheaper than that of 301 stainless steel and 304 stainless steel.

Good corrosion resistance

Though the production cost is low, 201 stainless steel still has good corrosion resistance, as well as hot and cold processing performance, which is enough to replace the 304 stainless steel products used in indoor, inland cities, and outdoor environments with low corrosiveness. 

A patent of 201 stainless steel

A few years ago, Yaoyi has applied for a patent. It is a patent on the production of 201 stainless steel through element replacement. Products produced in this way can get special properties, in addition, it will not rust outdoors for more than 20 years.

After that, Yaoyi has developed J1, J3 and J4 stainless steel. These types of stainless steel, under the same material and hardness, the elongation rate is more than 10% higher than similar products.

Is 201 stainless steel food grade?

No. It has certain acid and alkali resistance, high density, no bubbles, no pinholes, etc. It is used to produce high-quality materials for various watch cases and watchband bottom covers. Mainly used to make decorative tubes, industrial tubes, and some shallow stretched products.

However, food grade stainless steel is generally required to have much lower lead content in stainless steel materials than ordinary stainless steel. 201 stainless steel chemical composition bai points: (C)carbon: ≤0.15, (Si) silicon du:≤1.00, (Mn) manganese:5.5~7.50, (Cr) chromium: 16.0~18.0, (N) nitrogen:≤0.25, (P) phosphorus:≤0.060, (S) Sulfur:≤0.030,(Ni) Nickel: 3.5-5.5. Above all, it does not belong to food-grade stainless steel.

AISI 301 Equivalent: Components, Processing, and Applications

What is the difference between 201 and 304 stainless steel?


Mechanical properties

Omit the fatigue strength, 201 has a higher hardness, but its toughness and fatigue resistance are not as good as 304.

201 Stainless Steel Prices VS 304 Stianless Steel Prices

Because 304 stainless steel is chromium-nickel stainless steel, and 201 ss is low-nickel stainless steel, the price of 304 stainless steel is higher than that of 201.

The Colors

201 has higher manganese content, the surface is very bright with dark and bright, higher manganese content is easy to rust. 304 stainless steel contains more chromium, the surface is matte and does not rust.

Tht Anti-rust

Stainless steel is not easy to rust because the chromium-rich oxide formed on the surface of the steel body can protect the steel body. 201 stainless steel material belongs to high manganese stainless steel, which has higher hardness, high carbon, and low nickel than 304 stainless steel. In the same outdoor environment without washing, 304 stainless steel will not rust for 3-4 years, and 201 stainless steel will grow rust after 6 months.

The Compositions

The main difference between 201 and 304 stainless steel plate is the nickel content: The composition of 201 is 17Cr-4.5Ni-6Mn-N, which is an alternative to 301 stainless steel. It is magnetic after cold working, Used in railway vehicles. The composition of 304 is 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. For food production equipment, general chemical equipment, nuclear energy, etc..

AISI 301 Properties: Characteristics, Compounds, and Applications

What is 201 stainless steel?

201 stainless steel is a kind of austenitic stainless steel. It is formed by using nitrogen and manganese to replace part of nickel to form the austenitic phase.

In the early 1930s

Due to the volatility of nickel prices, many producers are prompted to find another austenitic stainless steel substitute with similar properties to 304 stainless steel. In the early 1930s, the original chromium-manganese austenitic stainless steel was produced, and manganese in the steel replaced part of the nickel. Since then, more research has been conducted on the specific composition ratios. Nitrogen and copper are used to control elements such as carbon and sulfur, which strongly affect the properties of the material. Finally, the 200 series is available.

At present

The main steel grades of 200 series stainless steel are J1, J3, J4, 201, 202. There are also 200 grades with lower nickel content control. As for 201C, it is the 201 stainless steel extension developed by individual steel plants in China at this later stage. The national standard of 201 is 1Cr17Mn6Ni5N, and 201C continues to decrease based on 201 The content of nickel increases the content of manganese.

stainless steel grades


The success of the application of 200 series stainless steel is that it is possible to replace 304 stainless steel in some specific applications. Most of the 200 series stainless steel sold in the Chinese market has almost no control of sulfur and carbon content by national standards, and manganese (and Nitrogen) replace part or all the nickel to produce austenitic stainless steel with lower nickel content.

The disadvantage of this series of materials is that the 18% chromium content and the low nickel content are not balanced to form ferrite. For this reason, the chromium content in the 200 series stainless steel is reduced to 15% to 16%, and in some cases, It is reduced to 13% to 14%, and its corrosion resistance is not comparable to that of 304 and other similar steels. Also, under the acidic conditions common in the corrosion parts of the deposition area and crevices, manganese and in some cases copper is reduced and then passivated. 


The role of chemistry. The destruction rate of 200 series steel under these conditions is about 10-100 times that of 304 stainless steel. Also, it is often impossible to control the residual sulfur and carbon content in these steels during production, and the materials cannot be traced back to the source, even in the recycling of materials. If Cr-Mn steel is not specified, it will become a dangerous mixed raw material for scrap steel, resulting in unexpectedly high manganese content in castings.

201 stainless steel has the characteristics of acid and alkali resistance, high density, no bubbles, no pinholes, etc. It is used to produce high-quality materials for various watch cases and watchband back covers. Mainly used to make decorative tubes, industrial tubes, and some shallow stretched products.

AISI 301 Stainless Steel Properties

What is the difference between 201 and 301 stainless steel?


a. 201 stainless steel material has certain acid resistance, bai alkali resistance, high density, polishing without bubbles, and no pinholes. It is used to produce high-quality materials for various watch cases and watchband bottom covers. Mainly used to make decorative tubes, industrial tubes, and some shallow stretched products.
 b. 301 is the steel grade that is most easily strengthened by cold deformation. Cold deformation can increase the strength and hardness of the steel and retain enough plasticity and toughness. Also, this steel has good rust resistance under atmospheric conditions, but The corrosion resistance of reducing media is poor, and the corrosion resistance of chemical media such as acid, alkali, and salt is poor, so it is not recommended to be used in harsh environments. 

Chemical composition

The main difference is the content of nickel and manganese, 301 nickel is 6%-8%, and manganese is 2%. 201 nickel is 3.5%-5.5%, manganese is 5.5%-7.5%. Therefore, 301 is higher in price and corrosion resistance than 201, and 301 contains more nickel. So it is more acid and alkali resistant. Not easy to rust. The inside of 201 does not contain nickel, does not have acid and alkali, and is easy to rust.


201 stainless steel is mainly used for decorative pipes, industrial pipes, and some shallow stretched products. 301 is mainly used in a cold working state to withstand higher loads, but also hopes to reduce equipment weight and rust-free equipment parts. Also, this steel is prone to work hardening when impacted by an external force, which can absorb more impact energy, and will provide more reliable safety guarantees for equipment and personnel. 301 is prone to work hardening during deformation and is used in places requiring higher strength.

What is the cheapest grade of stainless steel?

210 stainless steel properties

There are three types of cheapest stainless steel on the market: 201, 409, 410 stainless steel.

As one of the cheapest kind of stainless steel, the 201 ss chromium content is 16-18, and the nickel content is only between 0.3 and 1.2. There are also many 201 rolled plates on the market, and the price is relatively cheaper. 201 is more used in kitchen equipment, and tableware is rarely used. The surface of 201 is a bit worse than that of 304, and its stamping performance is also worse.

409 stainless steel is universal chromium, titanium stabilized du ferritic stainless steel, and its main application is the automobile exhaust system. Contains 11% chromium, which is the minimum amount to form a passive surface film for corrosion resistance of stainless steel. It has good high-temperature corrosion resistance, medium strength, good formability, and overall cost. Compared with carbon steel, 409 alloy has strong corrosion resistance and can be used as a substitute material for carbon steel in a mildly corrosive environment. Because of its higher corrosion resistance and high-temperature oxidation, it has advantages. Usually used in applications where appearance is a secondary quality of mechanical properties and corrosion resistance.

410 stainless steel contains 0.15% carbon, 13% chromium, C≤0.15, Si≤1.00, Mn≤1.00, P≤0.035, S≤0.030, Cr=11.50~13.50. 410 stainless steel has good corrosion resistance and machinability, General purpose blades, valves, mechanical parts, class 1 tableware (spoon, fork, knife, etc.).410 stainless steel has high strength; excellent machinability, hardened after heat treatment; magnetic; not suitable for harsh corrosive environments.
