ASTM A335 P11 Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service

ASTM A335 P11 is a seamless ferritic alloy-steel pipe within the chromium-molybdenum (Cr-Mo) system, engineered for high-temperature/pressure service. Its microstructure consists of tempered bainite or ferrite-pearlite (depending on heat treatment), where the controlled alloying of Cr (1.00-1.50%) and Mo (0.44-0.65%) ensures superior creep resistance and rupture strength within the 540-593°C range. Manufactured via seamless hot-finished or cold-drawn processes, the pipe requires normalization and tempering to enhance grain boundary stability. It is certified for ASME B31.1/B31.3-regulated power piping and high-temperature refinery/petrochemical pipelines.

C	Mn	P	S	Si	Cr	Mo
0.05%~0.15%	0.3%~0.6%	≤0.025%	≤0.025%	0.5%-1.00%	1.00%~1.5%	0.44%~0.65%

Mechanical Properties

Property	Standard Value
Tensile Strength	≥415 MPa (60 ksi)
Yield Strength (0.2% offset)	≥205 MPa (30 ksi)
Elongation	≥20%
Hardness (Brinell)	≤197 HBW

2. Key Adventages

High-Temperature Performance Advantages

Maintains excellent creep resistance at 540-593°C, with 2-3 times longer service life than carbon steel (e.g. A106)

Maintains rupture strength >60MPa under 593°C/100,000h condition

1.25% Cr content forms dense Cr₂O₃ scale, reducing oxidation rate by 80% vs carbon steel

Cost-Effectiveness Advantages

15-20% cost saving vs P22, most economical choice for <600°C service

Excellent high-temp stability extends maintenance intervals by 50% vs carbon steel

Fabrication Advantages

Standard PWHT(650-750°C) is sufficient, much simpler than high-alloy steels

Supports both hot bending(>950°C) and cold bending(annealing required)

Reliability Advantages

Normalizing+Tempering creates stable ferrite+pearlite structure

Complies with both ASME BPV Code and ASTM A335 standards

3. Key Applications

Power Industry: Power plant boilers (superheaters, reheaters, main steam pipelines)
Petrochemical Industry: Refinery hydrogenation units, cracking equipment pipelines
Natural Gas Transmission: High-pressure natural gas gathering pipelines
Industrial Boilers: High-pressure boiler heat exchangers, economizers, headers
Chemical Processing: High-temperature reactors, heat exchanger tubing
