ASTM A335 P5 Chrome Moly Pipes
Mcneil Instrument is a trusted ASTM A335 P5 Chrome Moly Pipes Manufacturer, Supplier & Exporter in India, USA, Turkey & Nigeria, delivering high-performance seamless ferritic alloy steel pipes designed for elevated-temperature service, petroleum refining, chemical processing, power generation, and heavy industrial applications.
ASTM A335 Grade P5 (ASME SA335 Grade P5) is a 5% Chromium – 0.5% Molybdenum (5Cr–½Mo) seamless alloy steel pipe grade engineered to provide high-temperature creep strength and resistance to hot-oil corrosion and scaling. The 5% chromium addition offers enhanced protection against hydrogen attack, sulfur-bearing hydrocarbon streams, and hot-steam oxidation compared to lower-alloy grades such as P11 or P22.
Mcneil Instruments manufactures and supplies P5 seamless chrome moly pipes in a full range of nominal pipe sizes (NPS), schedules, wall thicknesses, and custom cut lengths governed by ASME B36.10M. All P5 pipes are supplied in normalized and tempered or fully annealed conditions to ensure structural integrity and mechanical stability under sustained high-temperature loading.

What is ASTM A335 P5 Chrome Moly Pipe?
ASTM A335 P5 Chrome Moly Pipes are seamless ferritic alloy steel pressure pipes manufactured from a 5Cr–½Mo chromium-molybdenum alloy matrix designed for elevated-temperature process environments.
The core alloying additions include:
- 4.00% to 6.00% Chromium (Cr): Delivers resistance to scaling, hot-sulfidization, petroleum hydrogen attack, and oxidation.
- 0.44% to 0.65% Molybdenum (Mo): Increases high-temperature yield strength, creep-rupture capability, and resistance to thermal stress relaxation.
P5 seamless pipes are widely specified across petroleum refineries, delayed coking units, hydrocracking loops, chemical process furnaces, and steam piping networks where intermediate corrosion resistance and thermal endurance are paramount.
