It is mainly used to make high-quality seamless carbon steel, for boiler pipes, super heat pipes
Grade of high-quality carbon boiler steel: GrA, GrC
| Element | Grade A | Grade C |
| C | ≤0.27 | ≤0.35 |
| Mn | ≤0.93 | 0.29-1.06 |
| P | ≤0.035 | ≤0.035 |
| S | ≤0.035 | ≤0.035 |
| Si | ≥ 0.1 | ≥ 0.1 |
A For each reduction of 0.01 % below the specified carbon maximum, an increase of 0.06 % manganese above the specified maximum will be permitted up to a maximum of 1.35 %.
| Grade A | Grade C | |
| Tensile Strength | ≥ 415 | ≥ 485 |
| Yield Strength | ≥ 255 | ≥ 275 |
| Elongation rate | ≥ 30 | ≥ 30 |
In addition to ensuring chemical composition and mechanical properties, hydrostatic tests are performed one by one, hardness, flaring and flattening tests are performed.
