Choose By Thickness
Customize By Finishes
-
PolishedThe polished surface finish gives a shiny appearance to 304L SS sheets. It has a smooth surface that helps resist corrosion.
-
HairlineThe 304L SS sheets with hairline finish achieve aesthetic looks. They come with long and constant grind marks, like hair.
-
2B Surface2B finishes provide smooth and slightly mirrored sheet surfaces. This appearance is fulfilled through a milling process.
-
BA SurfaceBA finishes give a non-abrasive SS sheet surface. They typically have mirror-like finishing, making them more unique.
Advantageous Features
The 304L SS sheets have positive qualities, emphasizing their quality. Here are a few of those attributes.
- 304L has higher pitting resistance on chloride solutions due to increased molybdenum content.
- Works well in extreme temperatures with enhanced heat resistance
- Due to its outstanding rust resistance, it is ideal for numerous media.
- Suitable for low-degree temperature conditions
- Possess ideal weldable characteristics

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.
