2B is a term used to describe a smooth and reflective surface. The process of 2B involves cold rolling, heat treating, and pickling together with light rolling at the last part of the process to achieve that smooth and reflective surface.
2B is also considered the most used surface finish. This is the reason why most stainless steels are very shiny and reflective since 2B is the basis for polished and brushed finishes for stainless steel.
Everything You Need To Know:Stainless Steel Ties
The term 2B for stainless steel was used by ASTM A480 standard to define smooth and reflective cold-rolled annealed and pickled finish produced by adding the final process of light cold-rolled pass by using polished rolls.
ASTM A480 is not a company, but rather it is the specification that covers the general requirements for heat-resisting steel plates, flat-rolled stainless, stainless sheets, and stainless strips.
As aforementioned, a 2B finish is the result of a stainless steel finish defined by its smoothness and moderate reflective cold-rolled finish which has a similarity of production with the 2D finish but without the light cold rolling process.
2B Finish is also known to be opposed to common brushed finishes seen on appliances since 2B is moderately reflective that is somewhat similar to a foggy or moist mirror. 2B finish is used among other steel grades including 304 stainless steel.
Th3 2B finish is easy to maintain which makes it very versatile for many uses such as industrial applications and other equipment.
The process of a 2B finish starts with cold rolling then on to the heat treating and lastly pickling. The final touch is what other finishes do not have, which is the application of a light rolling to attain that smooth and moderate reflective shine.

The mechanical properties for AISI 304 2B helps you understand why it is a good stainless steel. For you to determine which stainless steel is best for you, here is a list of Mechanical Properties from different stainless steel grades provided by YAOYI.
The definition of steel grade is to classify different types of steel by looking into its mechanical properties and chemical composition. Each type of steel grade is different from one another as it has its own unique elements and purposes.
For AISI 304 2B, has low carbon (0.08%) and austenitic chromium-nickel components.
Tensile strength is the resistance of steel to breaking under tension. Tensile strength plays a vital role in the flexibility or formability of the steel. For A-304 2B Stainless steel, it has a tensile strength of 74,694 PSI (Per square inch).
If you are not sure what tensile strength you should use for your projects, you can contact us by clicking/tapping here. YAOYI will guide you to what tensile strength is appropriate for your projects since the wrong tensile strength risks your project from breaking.
Yield strength is when a steel is stressed by an amount that is less than it yields. This is also an important factor to determine a steel’s durability. Any steel that breaks easily under moderate tension is considered low steel grades that are not suited for big projects such as infrastructures.
In this case, the strength of AISI 304 2B is 70,343 PSI which means that it is capable of going under a large amount of stress without showing any signs of breaking or damage.
Some steels are capable of long stretches and this is important for its formability to be versatile. Steel elongation is the rate or percentage of how much the steel can stretch from its original length. AISI 304 2B has an elongation rate of 40% which is excellent for forming the steel into various shapes without breaking.

When it comes to common uses for the AISI 304 2B stainless steel, like any other type of steel, it is versatile as well but on a whole other level because of its mechanical properties and chemical composition.
Here are the common uses for A-304 2B stainless steel:
Yes, the AISI 304 2B is still a part of the food grade stainless steel level. In fact, 304s are the commonly used type for preparation, storage, and dining for food industries because of its corrosion-resistant and oxidation properties.
AISI 304 and A-304 2Bs are great for chemical containers as they can resist high levels of specific chemicals under moderate temperature and exposure to outside environment elements.
It is not surprising that 304 2B is present in kitchen appliances and kitchenware since most utensils in the kitchen have moderate to high reflective stainless steel materials including 304 2Bs.
Almost every construction has to have a 304 or 304 2B. This is the reason why people around the world always go for 304s because of its popularity and high endurance to extreme conditions and temperatures.
It’s moderate reflective shine is also what makes it attractive for most consumers.
