Chemical Composition
| Element | Heat Analysis % | Remark |
| C | ≤0.26 | Ensure weldability |
| Mn | ≤1.35 | Enhance strength and toughness |
| P | ≤0.035 | Low phosphorus to prevent cold brittleness |
| S | ≤0.015 | Low sulfur improving hot processing |

| Cr | ≤0.15 | - |
| Ni | ≤0.25 | - |
| Mo | ≤0.15 | - |
- Heat analysis is mainly used to monitor and measure changes in the chemical composition of raw steel tubes during the manufacturing process.
- Product analysis, on the other hand, is usually used to test the chemical composition of finished structural tubes, to which the chemical composition mentioned in daily purchasing usually refers.

Typical Application Areas
- Building Structures: Steel structure columns/beams, braces, trusses, curtain wall frames, factory building frames.
- Bridges and Transportation: Pedestrian bridges, viaducts, guardrails, lamp posts, transmission towers.
- Mechanical Equipment: Engineering machinery frames, conveyor equipment, agricultural machinery, container frames.
- Others: Scaffolding, shelving, amusement facilities, pipe supports, steel structure platforms.
Core Compare
-
There are three grades of A500, which are:
Grade B
Grade C
Grade D
Note: Grade B and Grade D have the same chemical composition requirements in ASTM 500. Tensile strength and elongation are also the same, except that Grade D has a higher yield strength and needs heat treatment.
- GR.B: General structures, buildings, machinery, cost-performance first choice
- GR.C: Heavy load, high-rise, long span, higher strength required
- GR.D: Low temperature/impact requirements, bridges, outdoor structures
