AISI 304L is one of the widely used grades of austenitic stainless steel renowned for its strong resistance to corrosion, flexibility and ease of manufacturing. The chemical composition is that it generally has a high level of chromium and nickel. Also, it has the special property of producing the drop of carbon also. This enhances its weldability, and it has the capability of withstanding the inner flow of hydrogen which improves its resistivity to corrosion, particularly in corrosive environments. AISI 304L is a popular choice for the use of its inertness and hygiene qualities for the food processing, chemical, and pharmaceutical industries. Sophisticated tables, charts and exchangeable documents which are solely dedicated to the problem of grades, chemical composition and mechanical properties of alloys should be found in any engineer’s and manufacturer’s hard drive. These tools help during the task of selection of materials, which ensures a way for specific applications plus the compliance with the standards and regulations of the industry.
Information on the AISI 304L austenitic stainless steel chemical composition Grade table is vital for engineers and manufacturers in that it provides the essential details. Therefore, this table is going to be created to show those exact percentages of the principal components such as Cr, Ni, C, Mn and others of AISI 304L alloy. As well, table lays information on the grades along with the grades them, considering differences in mechanical properties, corrosion resistance and comparison of the suitability for distinct applications. This table access to provides an open door for making informed decisions during material selection processes, checking that the materials picked are compatible and meet performance standards.

Advantages:
Excellent Corrosion Resistance: This type of AISI stainless steel has a very high resistance against corrosion in any environment, even the presence of acids and chloride ions.
High Strength: It has good mechanical characteristics and is resistant to strong forces. This makes it preferable for structural applications.
Ease of Fabrication: AISI 304, being readily-machinable, weldable, and formable, should be your go-to material when it comes to fabrication and design processes as it allows for efficient processes and diversified designs.
Hygienic Properties: Its smooth surface effect and relative inertness that will make it ideal for utilization in food processing, pharmaceutical and medical where cleanliness is paramount.
Wide Availability: AISI 304 presence in different shapes, sizes and finishes enable producers to make quality use of the product for all types of industrial and commercial applications.
Disadvantages:
Susceptibility to Pitting Corrosion: On chloride containing conditions AISI 304 has propensity for localized corrosion of the kind referred to as the pitting corrosion, particularly in an harsh environment.
Limited Heat Resistance: Dissimilar to AISI 304 that can hold out moderate temperatures with oxidation, at high temperatures which may lead to things like scaling and degradation can occur.
Cost: As compared to other stainless steel grades, AISI 304 could be quite expensive, especially in large-scale industries where major purchases are involved.
Not Suitable for Extreme Environments: It is not applicable to areas where alloys with high tolerance on aggressive acidic conditions or high temperature conditions which require specialized alloys have to be used.
Magnetism: AISI 304 is non-magnetic property being applied to the annealed state which makes it limited to those applications which require or have magnetic properties.

AISI 304L is one type of stainless steel that has 18-20% chromium, 8-12% nickel, and it should not contain more than 0. 03% carbon, which make it considerably effective for specific applications that does not allow carbide formation during the welding process.
It also has a lower carbon content that reduces the formation of carbides that can improve its immunity to intergranular corrosion in the welded part.
It is widely used in chemical vessels, heat exchange equipment, pipelines, food processing equipment, and medical instruments owing to its superior corrosion resistance and weldability.
Stainless steel AISI 304L is suitable for welding due to its low carbon content, while AISI 304H contains a higher carbon content which makes it suitable for high temperature applications.
