316 and 316L stainless steel have similar corrosion resistance and mechanical properties. The main difference is carbon content. 316L has lower carbon content, providing better resistance to sensitization and improved performance after welding.
| Grade | Feature | Typical Selection |
|---|---|---|
| 316 | Higher carbon version with excellent corrosion resistance | General industrial components |
| 316L | Lower carbon content with improved welding corrosion resistance | Chemical, marine and welded structures |
316 and 316L stainless steel round bars are internationally recognized under different standards. Equivalent grades help customers identify suitable materials according to regional specifications.
| Standard | UNS | W.Nr. | EN | JIS | BS |
|---|---|---|---|---|---|
| 316 Stainless Steel | S31600 | 1.4401 / 1.4436 | X5CrNiMo17-12-2 | SUS316 | 316S31 / 316S33 |

316 and 316L stainless steel contain chromium, nickel and molybdenum. The molybdenum addition improves resistance to pitting and crevice corrosion, especially in chloride-containing environments.
| Grade | C | Cr | Mo | Ni | Fe |
|---|---|---|---|---|---|
| 316 | ≤0.08% | 16.00-18.00% | 2.00-3.00% | 10.00-14.00% | Balance |
| 316L | ≤0.035% | 16.00-18.00% | 2.00-3.00% | 10.00-14.00% | Balance |
Mechanical properties depend on product condition, diameter and manufacturing process. The following values are typical reference values for hot rolled round bars.
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| 316 | ≥515 | ≥205 | ≥40 |
| 316L | ≥485 | ≥170 | ≥40 |
316L stainless steel round bar is often selected by comparing corrosion resistance, application environment and cost requirements with other stainless steel grades.
| Grade | Main Feature | Relative Cost | Typical Application |
|---|---|---|---|
| 304 | General corrosion resistance and good fabrication performance | Lower | General industrial components |
| 316L | Molybdenum alloyed with improved chloride corrosion resistance | Medium | Marine, chemical and pharmaceutical equipment |
| 904L | Higher alloy content for severe corrosion environments | Higher | Aggressive chemical applications |
