YUHONG GROUP has successfully completed the batch delivery of SA-335 P9 high-pressure alloy steel pipes!
Each pipe was individually checked for surface quality, dimensional tolerances, protection, and packaging to ensure that the products meet the ASME B31.1 standard and additional customer specifications.
| C | Si | Mn | Cr | Mo | P | S |
| ≤0.15 | 0.25-1.00 | 0.30-0.60 | 8.00-10.00 | 0.90-1.10 | ≤0.025 | ≤0.025 |
| Tensile Strength | Yield Strength | Elongation |
|---|---|---|
| ≥415 MPa | ≥205 MPa | ≥22%. |
Maintains high creep strength and ductility at 550-600℃, with a 10⁵h endurance strength ≥41 MPa.
Superheaters, reheaters, main steam pipes of supercritical boilers, and high-temperature and high-pressure pipelines in petrochemical installations.
