AISI 301 Equivalent: Components, Processing, and Applications

It is an austenitic chrome-nickel stainless steel that can be found in both the annealed and cold wrought stages of operation. It is designated by the American Iron and Steel Institute (AISI). It has the highest level of stretch formability of any stainless steel when annealed, and when heavily cold worked, it has the highest level of strength of any 300 series stainless steel. Yaoyi’s aisi 301 equivalent is made of stainless steel and has the highest level of stretch formability of any stainless steel.

Yaoyi’s cold working changes aisi 301 from a nonmagnetic to a magnetic material as a result of this transformation. When annealed, the material retains its nonmagnetic properties.

More importantly, while Yaoyi’s counterpart to Aisi 301 stainless steel is corrosion resistant in a wide variety of settings, its corrosion characteristics are weaker than those of Aisi 304 stainless steel in some situations.

AISI 301 Equivalent: Pricing

In response to rising demand from China and other emerging markets, the price of alloying elements added to stainless steels has risen significantly in recent years. Nickel prices have more than doubled in the last five years, reaching a level ten times higher than they were previously. 

In addition, the prices of chromium and molybdenum have also skyrocketed, as has the price of stainless steel scrap, which steelmakers rely on heavily for their production. 

Inevitably, stainless steels have suffered significant price hikes as well, with little hope of a price decrease in the near future. As a result of rising demand and the time necessary to develop new supply sources, nickel and other alloy prices are unlikely to fall back to the levels observed just a few years ago, if at all.

Due to this, higher prices are prompting stainless steel users to look for more cost-effective solutions: the best grade to use is a combination of engineering and economic criteria, and the best grade to use may fluctuate depending on the cost environment in which they operate. 

It is estimated that around 60% of stainless steel applications around the world are made from grade 304, which is the most widely used stainless steel grade.

301 stainless steel can also be applied to stainless steel worm gear reducers.

What are the aisi 301 equivalents in Stainless Steels, and how do they differ from other materials? 

The austenitic structure of Yaoyi’s aisi 301 stainless steel, which contains chromium and nickel as its principal constituents, is the most prominent feature of the steel. One of the alloy’s most distinguishing characteristics is that it is nonmagnetic in its annealed state, but when cold worked, it becomes magnetic once more.

As defined by American standards, aisi 301 can be easily adjusted to obtain a wide range of mechanical properties with little effort. For Yaoyi’s aisi 301 materials, quarter hard, half hard, and full hard temper grades are the most common temper grades that are currently available on the market.

What are the Best Equivalents?

If the austenitic 200 series stainless steels, duplex stainless steels, and ferritic grades are selected, developed, manufactured, and used properly, they can all be used in place of aisi 304 and 316 stainless steels. For further information, see

Because the alloying elements chromium and molybdenum in stainless steel are those that have the largest impact on corrosion resistance, it is appropriate to mention them in this context. It is possible to distinguish between different classes of steel based on their chromium and molybdenum concentrations, which are utilized to discriminate between them within an alternative group in terms of corrosion resistance.

In addition, nickel concentrations in the well-known austenitic Yaoyi’s aisi 300 series grades are among the highest currently available on the market. It is possible to form the austenite crystal structure when manganese is added to the austenitic 200 series grades, which contain less nickel than the prior grades, resulting in the formation of the crystal structure.

AISI 301 Equivalent: Material Types 

The fact that these grades contain an austenitic crystal structure means that their mechanical and production properties are similar to those of the better familiar 300 series of stainless steel.

Because ferritic grades have the same crystal structure as carbon steel, they have mechanical properties that are identical to carbon steel, as well as manufacturing properties that are identical to carbon steel. The ferritic grades, on the other hand, do not contain any nickel additives.

Duplex grades, on the other hand, are not fully austenitic in their composition. The microstructure is produced to contain an equal amount of austenitic and ferritic grains, which generally means that the nickel content is approximately half that of an austenitic grade with the same chromium content.

Production Process


Even in moderately hard environments, Yaoyi’s AISI 301 steel delivers outstanding corrosion resistance that is virtually as good as 304 stainless steel in mild environments.

In addition to wires and strips, Yaoyi’s aisi 301 stainless steel is available in tensile strengths of up to 1800 Mpa in both wire and strip form. This is possible because of the tensile strength, which allows it to process tempers ranging from 1/16 Hard to Full Hard in one operation. AISI 301 wires and strips are available in various sizes and shapes at Yaoyi.

Solution Treatment 

In addition, Yaoyi’s aisi 301 equivalent is subjected to solution treatment annealing at 1120 degrees Celsius, followed by rapid cooling, before being used. Yaoyi’s aisi 301 equivalent material, particularly in its low carbon version, is used primarily in high strength stainless steel applications, according to the International Standards Organization.


It is estimated that the work hardening rates of Yaoyi’s aisi 301 are in the range of a 14MPa increase per hour of exposure, which is fairly substantial. It has been possible to reduce the area of cold work by one percent while still producing rolls of exceptional strength as a result of this feature.

Cold Rolling  

There are cold rolling and forming operations involved in the production process. All common welding procedures, including stick welding, are compatible with Yaoyi’s equivalent grade of aisi 301 (aisi 301 equivalent).

As a result of the cold rolling process, this type hardens at a higher rate than the others. It is more difficult to progress through formability than it is to move through the other grades in the family. While the material is being subjected to strain hardening, the austenite structure of the material is transformed into martensite.


There are various issues to be concerned about throughout the welding process, including the material losing its temper in the weld and the heat-impacted zone. Welding 301 type steel together is most commonly accomplished through the use of spot welding.


Yaoyi’s aisi 301 equivalent displays strong corrosion resistance, as well as excellent oxidation resistance, when used intermittently to provide services at temperatures up to 840°C and continuously to provide services at temperatures up to 900°C, according to the manufacturer. Tempers have ranged from 1001 degrees Celsius up to 1010 degrees Celsius and higher.

However, in order to attain the highest possible level of corrosion resistance, aisi 301 equivalent welded components must be subjected to extensive testing.

Yaoyi’s chosen materials for manufacture have the ability to endure corrosion, and this is what is accountable for this. Steel materials and grades that are resistant to corrosion offer a number of advantages over other materials and grades. The functionality given by the aisi 301 equivalent is comparable to the functionality provided by the 304 counterpart. Using this method at room temperature is beneficial in mildly corrosive environments.

In the end, Yaoyi’s cold rolled 301 type steel provides higher corrosion protection over annealed steel in terms of corrosion resistance when compared to other steels. To reach the appropriate hardness without the need of annealing, this grade is hardened by cold working, specifically cold rolling, rather than by heating.
