304L Stainless Steel Plate
Product Details
What is 304L Stainless Steel Plate
304L Stainless Steel Plate is a sheet of steel that is resistant to corrosion and has a low carbon content. It is often used in applications where corrosion resistance is important, such as in food processing and medical equipment. It is also used in applications where a low carbon content is desired, such as in automotive and aerospace components.
It is common practice for 304L to be dual certified as 304 and 304L. The low carbon chemistry of 304L combined with an addition of nitrogen enables 304L to meet the mechanical properties of 304.
Alloy 304/304L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. The alloy has excellent resistance to inter-granular corrosion in the as-welded condition. Alloy 304/304L has excellent strength and toughness at cryogenic temperatures.
Alloy 304/304L is non-magnetic in the annealed condition, but can become slightly magnetic as a result of cold working or welding. It can be easily welded and processed by standard shop fabrication practices.

304L Fabrication Data
304L is an austenitic stainless steel that is widely used for its excellent corrosion resistance, weldability, and formability. It is also known for its high strength-to-weight ratio. It is non-magnetic and is often used in the food and beverage, medical, and aerospace industries. It is commonly used in the fabrication of tanks, pipes, and other components.
Welding:
304L is typically welded using the Gas Tungsten Arc Welding (GTAW) process. It is important to use the correct filler metal when welding 304L. Common filler metals include 309L and 316L. It is also important to use the correct shielding gas and welding parameters to ensure the weld is of high quality.
Forming:
304L is a relatively easy material to form. It can be cold formed using standard forming techniques, such as bending, drawing, and spinning. It can also be hot formed using a variety of methods, such as hydroforming and die-casting.
Machining:
304L is a relatively easy material to machine. It is not particularly hard and can be machined using standard cutting tools. It is important to use the correct cutting parameters and coolant to ensure the best possible finish and surface integrity.
Heat Treatment:
304L can be heat treated to increase its strength, hardness, and corrosion resistance. It is typically annealed at temperatures between 1850-2050°F (1010-1121°C). It can also be solution annealed at lower temperatures.
