What is 304L/304 Grade Stainless Steel?
304L Stainless Steel
304L grade stainless steel is a specific type of stainless steel alloy that is a variation of the 304 grade. The “L” in 304L stands for “Low,” indicating its reduced carbon content compared to standard 304 stainless steel.
304 Grades Stainless Steel
304 stainless steel is a popular and widely used stainless steel alloy grade. It belongs to the family of austenitic stainless steels known for their excellent corrosion resistance and mechanical properties.
304L VS 304 Stainless Steel
- 304L: The “L” stands for “low carbon,” which improves weldability and reduces the risk of carbide precipitation during welding. It’s often chosen for applications that require welding.
- 304: This standard grade has a higher carbon content, which gives it slightly higher strength compared to 304L, but it may be less resistant to intergranular corrosion after welding.
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.

Type 304L/304 Stainless Steel Price
The 304L stainless steel is usually slightly higher than that of 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.
