ASTM A335 is a specification for seamless ferritic alloy-steel pipe intended for high-temperature service. The grades covered under this specification include P1, P2, P5, P11, and P91, each designed to withstand elevated temperatures and pressures. These pipes are commonly used in power plants, petrochemical plants, and other high-temperature applications.
The following table outlines the chemical composition of the various grades of ASTM A335 alloy steel seamless pipe:
| Grade | C (%) | Mn (%) | P (%) | S (%) | Cr (%) | Mo (%) | Si (%) | V (%) |
|---|---|---|---|---|---|---|---|---|
| P1 | 0.10 | 0.30-0.60 | 0.025 | 0.025 | 0.40-0.60 | - | 0.10-0.40 | - |
| P2 | 0.10 | 0.30-0.60 | 0.025 | 0.025 | 0.40-0.60 | 0.10-0.20 | 0.10-0.40 | - |
| P5 | 0.10 | 0.30-0.60 | 0.025 | 0.025 | 0.50-0.80 | 0.10-0.20 | 0.10-0.40 | - |
| P11 | 0.10 | 0.30-0.60 | 0.025 | 0.025 | 0.40-0.60 | 0.40-0.60 | 0.10-0.40 | - |
| P91 | 0.08 | 0.30-0.60 | 0.020 | 0.010 | 8.00-9.50 | 0.85-1.05 | 0.50-0.60 | 0.15-0.25 |
The following table presents the mechanical properties of the ASTM A335 grades:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| P1 | 205 | 415-550 | 20 | 160-207 |
| P2 | 205 | 415-550 | 20 | 160-207 |
| P5 | 205 | 415-550 | 20 | 160-207 |
| P11 | 205 | 415-550 | 20 | 160-207 |
| P91 | 240 | 550-690 | 20 | 200-250 |
The steel grades under ASTM A335 are categorized based on their chemical composition and mechanical properties, with P91 being the most advanced in terms of high-temperature strength and creep resistance.
ASTM A335 alloy steel seamless pipes are widely used in:
While ASTM A335 grades are widely used, there are alternative grades that may be considered based on specific requirements:
These alternatives may provide similar performance characteristics depending on the application and service conditions.
