In today’s competitive industrial world, materials that combine strength, corrosion resistance, and durability are in high demand. Among these, Stainless Steel 316L Round Bars have earned a strong reputation for their exceptional properties and reliability. Whether used in chemical processing, marine environments, or food-grade applications, SS 316L round bars deliver unmatched performance.
As a leading SS 316L Round Bar Supplier, we understand the importance of quality materials that meet international standards. Our products are manufactured using advanced technology and precision engineering, ensuring superior finish, dimensional accuracy, and long-lasting performance.
What is SS 316L Round Bar?
SS 316L Round Bar is a low-carbon version of 316 stainless steel, offering enhanced resistance to intergranular corrosion after welding. The “L” in 316L stands for low carbon, which improves weldability and minimizes carbide precipitation. This makes it ideal for applications requiring high corrosion resistance, especially in chloride or acidic environments.
These bars are typically made using the finest quality raw materials, melted and processed under strict quality control systems. SS 316L round bars are available in various diameters, lengths, and finishes to meet diverse industrial needs.
Chemical Composition of SS 316L
| Element | Percentage (%) |
|---|---|
| Carbon (C) | 0.03 max |
| Chromium (Cr) | 16.0 – 18.0 |
| Nickel (Ni) | 10.0 – 14.0 |
| Molybdenum (Mo) | 2.0 – 3.0 |
| Manganese (Mn) | 2.0 max |
| Silicon (Si) | 0.75 max |
| Phosphorus (P) | 0.045 max |
| Sulfur (S) | 0.03 max |
| Iron (Fe) | Balance |
The addition of molybdenum enhances resistance to pitting and crevice corrosion in chloride environments, while nickel and chromium provide excellent toughness and oxidation resistance.
