Stainless steel is one of the alloys that has been famous for its versatility in many industries. Its main feature, which is corrosion resistance, makes it famous. Now, AISI 304L stainless steel coil material has different elements like iron, carbon, and Chromium.
Moreover, the alloy is the main base for kitchen accessories, architecture, and medical equipment. The interaction between the environment and its composition prevents corrosion.
Standard stainless steel has 10.5% Chromium and less than 1.2% Carbon. Other elements are added to this mixture depending on the desired enhancement.
With its wide usage, different grades have entered the market throughout the years. These grades also rose due to the unique demand composition for each industry or product. One of the most common grades is 304L stainless steel.
It also has “excellent corrosion resistance and value.” Which makes it famous around the world.
Yaoyi is an excellent supplier and manufacturer of 304L stainless steel coils. We have been producing excellent quality 304L stainless steel coils since 1996. 25 years of production and sales experience has given us a huge deposit of knowledge about stainless steel. When you ask for it, we can provide you with the best quality stainless steel coil solutions based on our experience.
AISI 304L is one of the grades of stainless steel that is globally manufactured. It has eight to 12% of Nickel, 18 to 20% of Chromium, 2% Manganese, 1% Silicon, and 0.03% Carbon. This grade is like the infamous 304 grade but with lower carbon composition.
The carbon composition affects the steel’s resistance to corrosion. So, 304L’s lower carbon content helps “cut the carbide precipitation during welding.” Making it withstand even the severe corrosive environment.
Moreover, the L in 304L means “low carbon,” while the AISI only means American Iron and Steel Institute. Meaning, the AISI 304L stainless steel grade complies with the professional standard.
The ‘L’ in 304L stands for ‘Low Carbon.’ This variant of 304 stainless steel has lower carbon content, which helps in preventing sensitization during welding and other thermal processes.
With its resemblance to other grades, AISI 304L can be mistaken for something else. So, you must know how to identify grade differences. To help you, here are the factors that you can look into to know which one is the AISI 304L stainless steel.
The AISI 304L grade of stainless steel is an austenitic T 300 series. Austenitic stainless steel has a high percentage of Chromium and Nickel, with a low-carbon mixture. These kinds of stainless steel are also known for their formability and durability. Thus, the austenitic type of steel is the most used grade out of all the others.
The AISI 304L grade stainless steel has an exemplary corrosion-resistant feature. It can withstand even in a severe environment without getting any damage. With its 18% chromium component, AISI 304L can form a passive oxide layer to help protect the steel.
The percentage of carbon also affects the resistance of AISI 304L to corrosion. During the welding process, there is a phenomenon that happens. It’s called “chrome carbide precipitation.” The chrome merges with the carbon. Then, lessens the zone that provides corrosion resistance.
Thus, lesser carbon means the lesser risk for the combination of the two elements. Meanwhile, AISI 304L has moderate resistance to oxidation.
These physical properties are the considerations you have to make before its application. The AISI 304L has a density of 8.00 Kg/m3, which is 0.5 denser than the average grades. It also has thermal conductivity and electric resistivity of 16.2W/m.K and 0.072 x 10-6 Ω .m.
Moreover, this grade manages 1450 degrees Celsius of temperature before melting. It also has a modulus of elasticity at 193 GPa.
The last parts revealed that AISI 304L stainless steel has eight to 12% Nickel and 18 to 20% Chromium. There is also a lower Carbon percentage of 0.03% than 0.08% of the usual 304. A 2% Manganese, 1% Silicon, 0.015b)% Sulphur, and 0.10% Nitrogen are also present in the mixture.
Moreso, there is a flat Iron in the composition of AISI 304L stainless steel. At the same time, there is 0.045% of Phosphorus.
The AISI 304L stainless steel exudes a tensile strength of 500 – 700 MPa. Proof stress of up to 200 Min MPa and an elongation of 45 Min%. These properties of stainless steel predict the capacity and usefulness of the material. Similarly, ISU-NDE also stated that “these properties help classify and identify the material.”
Because of the lower carbon percentage present, the AISI 304L has excellent weldability. Even on the heavy welded section, post-weld annealing is not required. But, Grade 321 can be an alternative solution if the heat treatment is not working.
304L stainless steel type functions for most accessories and industries because of its composition.
In austenitic steel, the heat treatment helps extract cold and precipitated chromium carbides. But, AISI 304L stainless steel can’t be solidified through heat treatment. Instead, it requires rapid cooling after heating to 1010- 1120°C for post-treatment.
AISI 304L has many applications because of its superb formability and durability. Various industries have also benefited from the features of this steel grade. This grade is versatile as it caters to home, commercial, automotive, and medical uses. Hence the popularity as well.
To be more specific, the 304L stainless steel usages are the following:
As mentioned above, 304L is a type of austenitic steel. That consists of elements with non-magnetic properties. It is the only type of stainless steel that is not magnetic. All the other classes are susceptible to magnetic reactions.
The austenitic stainless or the 300 series is non-magnetic, especially when newly formed. However, the 304 grades can be magnetic after pressing, cutting, and blasting. This change is because these grades could pick up foreign particles in such a process.
With these particles, some structures might change. Hence the effect on the magnetic susceptibility of the alloy. But, if the stainless steel has more Nickel in its composition, it is unlikely to change.
With tons of unique grades in the market, 304 and 304L stainless steel have the most similarity. There’s no significant difference between the two. Whereas their uniqueness can make or break your decision. Their chemical compositions are identical except for the percentage of carbon. Whereas 304 has 0.08 maximum while 304L has 0.03.
Their difference plays an integral part in the corrosion resistance performance. The AISI 304L is less susceptible to rust or corrosion because of the little contrast.
But, the 304 also has its mechanical composition advantage. The AISI 304L has a “slight, but noticeable, reduction in key mechanical performance.” The tensile strength of AISI 304L is lower than the standard 304. It is also the same with yield strength, but the change in this part is more unnoticeable.
To sum it up, the dissimilarity of 304 and AISI 304L lies in the carbon percentage and the structure.
While both grades are almost identical, they are still used for different purposes. People who need the alloy for commercial uses pick the 304 stainless steel. It can be for drink brewing, food processing, and the like.
The standard grade can withstand chemical elements brought by various remnants. It is also easy to clean.
On the other hand, the 304L caters to industrial purposes. It can still be used for various commercial and home uses. Since it has a lower carbon percentage, its corrosion resistance is exemplary. Thus, it can hold out against low and high temp.
AISI 304L’s application is to heat exchangers, chemical containers, and mining equipment.
To simplify, if you need a lot of welding, 304L is the perfect one. But, if you want more strength in the structure, you may opt to use the standard one.
