304 stainless steel is one of the most widely used austenitic stainless steel grades in the world. It is known for its excellent corrosion resistance, good formability, and balanced mechanical properties. The typical chemical composition includes approximately 18% chromium and 8% nickel, which provides outstanding resistance to oxidation and corrosion in many environments.
304L stainless steel is the low-carbon version of 304 stainless steel. The reduced carbon content significantly minimizes the risk of intergranular corrosion after welding, making 304L stainless steel especially suitable for welded structures, pressure vessels, and chemical equipment.
| Property | 304 Stainless Steel | 304L Stainless Steel |
|---|---|---|
| Carbon Content | ≤ 0.08% | ≤ 0.03% |
| Weldability | Good | Excellent |
| Corrosion Resistance | Excellent | Excellent (better after welding) |
| Strength | Slightly higher | Slightly lower |
| Typical Applications | General use | Welding-intensive applications |
Both grades are non-magnetic in annealed condition and widely used across industrial, commercial, and architectural sectors.
304 stainless steel contains a maximum of 0.08% carbon, which makes it more versatile and easier to weld. It is often used in various applications, including kitchen equipment, food processing, and architectural purposes, where its corrosion resistance and aesthetic appeal are valued.
304L stainless steel, on the other hand, is a low-carbon version of 304, with a maximum carbon content of 0.03%. This lower carbon content helps to eliminate the risk of sensitization during welding, which can lead to corrosion in certain environments. As a result, 304L is often preferred for applications where the material will be subjected to high temperatures or welding processes.
To summarize, the main difference between 304 and 304L stainless steel is their carbon content. 304L has a lower carbon content, making it more suitable for welding and high-temperature applications, while 304 is more versatile and commonly used in various general-purpose applications.
Our 304 and 304L stainless steel products conform to international standards like ASTM, JIS, and EN.
Equivalent grades for 304 stainless steel in different standards are as follows:
Please note that while the chemical composition and general properties are similar, there may be slight differences in specific requirements and tolerances between the various standards. When using equivalent grades for specific applications, it’s essential to check the relevant standards and specifications to ensure suitability and compliance.
Equivalent grades of 304L stainless steel in other standards are as follows:
Just like with 304 stainless steel, it’s important to consider that while the chemical composition and general properties are similar in equivalent grades, there might be slight differences in specific requirements and tolerances between the various standards. Always refer to the relevant standards and specifications for your specific application to ensure appropriate use and compliance.

The 304L stainless steel is usually slightly higher than the standard 304 stainless steel price. The price difference between the two grades is usually not significant but may vary depending on factors such as market conditions, availability, and supplier pricing policies.
The reason for the slight price difference is mainly due to the lower carbon content in 304L, which makes it more weldable and more resistant to intergranular corrosion after welding. This improved weldability and corrosion resistance make 304L the first choice for some applications, at a slight price increase compared to standard 304 stainless steel.
However, it is worth noting that stainless steel prices can fluctuate over time due to various factors, including changes in raw material costs, global supply and demand, and economic conditions. For current, accurate pricing information, I recommend checking with a reputable stainless steel supplier or market source for the latest market prices for 304 and 304L stainless steel.
Type 304L and 304 stainless steels are both part of the 300 series of austenitic stainless steels, known for their excellent corrosion resistance and versatility. Here’s a breakdown of their main uses and industry applications:

The primary difference lies in the carbon content. 304L has a maximum carbon content of 0.03%, whereas standard 304 allows up to 0.08%. This low-carbon composition makes 304L the preferred choice for welded structures to avoid “weld decay” (intergranular corrosion) without the need for post-weld annealing.
