304 STAINLESS STEEL FEATURES

Low Carbon Content

304L contains a maximum of 0.03% carbon, compared to the 0.08% carbon in 304. The lower carbon content helps minimize or eliminate carbide precipitation during the welding process.

Good Corrosion Resistance

Just like standard 304 stainless steel, 304L is highly resistant to a wide range of atmospheric, chemical, and food industry exposures.

Good Formability and Weldability

The lower carbon content in 304L provides better weldability over 304 stainless steel and is less susceptible to intergranular corrosion after welding or stress relieving.

Heat Resistance

Similar to grade 304, it can withstand relatively high temperatures, making it suitable for applications requiring exposure to heat.

Durability

Maintains its strength and toughness in cryogenic and high temperatures.

Non-Magnetic

It is non-magnetic in the annealed condition and can become slightly magnetic when cold worked.

Aesthetic Appeal

304L has a clean, attractive appearance, making it suitable for visible structural applications like architectural accents.

Hygienic

The alloy's ease of cleaning and lack of surface contamination makes it ideal for food and pharmaceutical processing environments.

304L stainless steel FAQ

How does 304L differ from 304 stainless steel?

The main difference lies in the carbon content; 304L has a maximum carbon content of 0.03%, while 304 can have up to 0.08%. This difference makes 304L more suitable for welding and high-temperature applications.

Why is 304L stainless steel preferred for welding?

The lower carbon content minimizes carbide precipitation in the heat-affected zone near the welded seam, reducing the risk of corrosion.

Is 304L stainless steel magnetic?

In its annealed state, 304L is generally non-magnetic, although it can become slightly magnetic after cold working.

What temperatures can 304L stainless steel withstand?

It maintains its properties within a similar temperature range as 304, up to about 870°C (1598°F), with improved performance in the range of 425-860°C (797-1580°F) due to reduced carbide precipitation.

Is 304L stainless steel recyclable?

Yes, like most stainless steels, 304L is 100% recyclable without degradation in quality.
