304L / 1.4301 Stainless Steel | Intamet Ltd
304L is a low carbon stainless steel with high corrosion resistance, excellent formability, and weldability.
"Stainless steel grade 304L stands out as a distinct variant of the widely recognised 304 stainless steel. Characterised by its reduced carbon content, 304L offers enhanced heat resistance, making it especially suitable for high-temperature applications. One of its notable attributes is the minimised carbide precipitation during welding, which directly translates to superior corrosion resistance.
When exposed to challenging environments, particularly those with salt water or other corrosive elements, 304L demonstrates unparalleled durability. Its robust defence against a broad spectrum of both organic and inorganic chemicals solidifies its reputation. As a result, this grade is highly sought after in diverse industries, from construction and marine projects to medical equipment manufacturing and food processing. Its versatility and reliability make it an invaluable asset in numerous applications."
304L stainless steel has good formability and weldability. It can be easily fabricated and formed into various shapes and is easy to be welded using standard welding methods. This makes it an ideal choice for applications that require a high degree of flexibility and versatility.
One of the most common applications of 304L stainless steel is in construction, particularly in the construction of buildings and infrastructure. It is used in a wide range of building components, including handrails, structural supports, and architectural cladding. Additionally, 304L stainless steel is also commonly used in kitchenware and medical equipment. It is non-toxic and non-magnetic, making it suitable for use in food processing equipment and surgical instruments.
Other common applications include automotive and aerospace, chemical processing, oil and gas exploration and production, and power generation. 304L stainless steel is also used in the production of coins and jewellery, due to its resistance to tarnishing.
304L stainless steel is a versatile material. It resists corrosion and is easy to shape and weld. It can be used in many industries and applications.

It's a mixture with less carbon than 304 stainless steel, so it's less likely to get intergranular corrosion. It is also known as "low carbon" or "L" grade stainless steel.
Variants of 304
There are several variants of stainless steel 304, some of the most common include:
- 304L: This variant of 304 stainless steel has a lower carbon content, making it less susceptible to intergranular corrosion. It is also known as "low carbon" or "L" grade stainless steel.
- 304H: This variant of 304 stainless steel has a higher carbon content, making it more suitable for high-temperature applications. It is also known as "high carbon" or "H" grade stainless steel.
- 304N: This variant of 304 stainless steel has higher nitrogen content which improves its strength and toughness.
- 304LN: This variant of 304L stainless steel has higher nitrogen content which improves its strength and toughness.
- 304Cu: This variant of 304 stainless steel contains copper, which improves its corrosion resistance.
- 304F: This variant of 304 stainless steel contains sulfur, which improves its machinability.
There are different types of stainless steel made from the original 304 stainless steel. These types have the same ability to resist rust and be shaped as the well-known grade. Moreover, they come with added properties tailored for distinct applications.
