ASTM A335 / ASME SA335 P11 Seamless Alloy Steel Pipe For Hydrocracking Furnace
ASTM A335 P11 alloy steel seamless pipe is specified under the ASTM A335/A335M standard, which covers seamless ferritic alloy steel pipes for high-temperature and high-pressure service. The ASTM A335 P11 alloy steel pipe features a balanced chemical composition of chromium, molybdenum and silicon. The chromium element enhances high-temperature oxidation and corrosion resistance, molybdenum improves creep strength and high-pressure durability, while silicon optimizes high-temperature surface stability. Unlike carbon steel pipes, P11 alloy steel pipes maintain stable mechanical performance under long-term high-temperature and high-pressure working conditions, making it a core material for thermal power, petrochemical and industrial high-temperature piping systems. As a seamless pipe product, it eliminates welding seam defects, ensuring integral structural uniformity and higher pressure-bearing safety.
Chemical Composition(%):
| Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) | Chromium (Cr) | Molybdenum (Mo) |
| 0.05-0.15 | 0.30-0.60 | ≤0.025 | ≤0.025 | 0.50-1.00 | 1.00-1.50 | 0.44-0.65 |
Mechanical Properties:
| Tensile Strength (Min) | 415 MPa (60ksi) |
| Yield Strength (0.2% Offset, Min) | 205 MPa (30ksi) |
| Elongation (50mm gauge length,Min ) | 30% |
Key Features of ASTM A335 P11 Alloy Steel Seamless Pipes:
