Jindal SS 304 Sheets & Plates Supplier

Jindal SS 304  workhorse of the stainless steel world. From kitchen equipment and surgical tools to chemical tanks and architectural panels, SS 304 is practically everywhere. But what many people don’t realize is that 304 isn’t just one steel grade—it comes with variations, namely 304L and 304H.

At a glance, they all belong to the same 18/8 family—meaning 18% chromium and 8% nickel—but these subtle suffixes (L and H) represent important differences in carbon content, heat resistance, and mechanical strength. And those differences can seriously affect your project if you’re not aware of them.

So what sets them apart?

  • 304 is the standard, all-purpose stainless steel grade.

  • 304L is the low-carbon version, ideal for welding and corrosion resistance.

  • 304H is the high-carbon variant, built for high-temperature environments.

Stainless steel is one of the most widely used materials in industries ranging from food processing to chemical manufacturing, construction, and medical equipment. Among the many grades available, the 300 series—particularly 304, 304L, and 304H—stand out for their excellent corrosion resistance, formability, and versatility.
