U Channel Chemical Composition
| Material | C (Carbon) | Si (Silicon) | Mn (Manganese) | P (Phosphorus) | S (Sulfur) |
| JIS G3101 SS400 | ≤0.25% | — | — | ≤0.050% | ≤0.050% |
Note:
Unlike some alloy structural steels, JIS G3101 SS400 channel steel does not require strict limitations on the content of carbon, silicon, and manganese. SS400 is a common carbon structural steel grade. To ensure the excellent welding performance and processing properties of SS400 steel, the phosphorus and sulfur elements need to be limited.
U Channel Mechanical Properties
| Material | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness |
| JIS G3101 SS400 | ≥245 MPa (t≤16mm) | 400–510 MPa | ≥17% | Approx. 120–180 HB |
Note:
The mechanical properties of JIS G3101 SS400 channel steel will fluctuate slightly due to changes in steel thickness and production processes. SS400 steel has superior welding properties, cutting processing properties, and strength, and is therefore applied in various ordinary construction projects such as steel structures, bridges, and others.
