304L and 304 Stainless Steel Sheet Differences
304 and 304L SS sheet grades have the exact content of chromium and nickel. They are also known as “18/8” in the stainless steel series. However, the carbon content is the only thing that differentiates them from one another.
The 304L sheets contain 0.030 % carbon, whereas the 304 has 0.08%. Here is an example of how minor differences in content cause them to differ.
Anti-Corrosion Strength
304-SS Grade
- Resistance to aggressive organic substances is 11% of nickel
- In oxidizing environments, the 19% chromium in 304 improves its resistance.
304L-SS Grade
- They are ideal for areas where the corrosion is potent enough to cause heat-affected sections.
- In the majority, 304L performs consistently in corrosive situations.
Suitable Fabrication Techniques

The cold-forming method enhances material robustness, hardness, and a little magnetism.
- Ductile
- Easily Form

- The 304L stainless steel possesses simplicity to weld.
- They do not require post-treatment.

304 is susceptible to work chip breaking and hardening. Therefore, they undergo proper machining with
- Slower speed
- Sharp tool
- Heavier feeds

750 °C to 1150°C are the suggested hot temperature working processes. Higher temperature improves sheets’ resistance.
