ASTM A355 Grade P2 Seamless Alloy Steel Pipe
Alloy pipes are tubular with higher percentages, than standard carbon steel pipes, of alloying elements as Molybdenum (Mo), Chromium (Cr), Nickel, etc. Actually, the ASTM A335 covers “low-alloy” steel pipes, i.e. pipes that have a total amount of alloying elements below 5%. The addition of higher percentages of alloying elements (example Nickel and Chromium) transforms the steel into higher alloys, like stainless steel, duplex, up to super-alloyed materials like Inconel, Hastelloy, Monel, etc.
Alloy steel pipes are used in the energy industry for high temperature and very low-temperature service (cryogenic), or for applications with very high pressures.

ASTM A355 Grade P2 ALLOY STEEL SMLS PIPE
ASTM A335 P2 Pipe has 0.44% molybdenum and 4% chromium. It is a low carbon steel with 0.015% carbon and can be welded without filler materials and at room temperature because of the low carbon content.The minimum yield strength of the products is 205MPa and the minimum tensile strength is 415MPa. The ASTM A335 P2 Chrome Moly Pipe also has manganese, phosphorus, sulfur and silicon in the composition.
The pipes come in 3mm to 12mm wall thickness with 1/8NB to 24NB nominal bore sizes. The products come in different pressure capacities ranging with sch20 through XXS schedules. The A335 Gr P2 Pipe can also be further hardened by heat treatment. It could be treated with full or isothermal annealing. There are round, square, rectangular and hydraulic pipe forms. The Sa335 P2 Pipe can be either cold drawn or cold rolled.
The length of the pipes can be single random, double random and cut to length sizes. There are different pipe ends such as beveled, plain and threaded ends for varying application types. The ASTM A335 P2 Steel Pipe is a type of ferritic alloy pip that can be used for high temperature services such as petroleum industrial pipe lines, heat exchangers, oil and gas transmission pipes.

ALLOYING ELEMENTS
The addition of Molybdenum (“Moly”) increases the strength of the steel and its elastic limit, enhance the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement and prevents pitting.
Chromium, a key element also for stainless steel alloys, prevents steel oxidation at elevated temperatures and increases the resistance of steel to corrosion. It enhances the tensile, yield, and hardness properties of low-alloy pipes at room temperatures.
Other alloying elements, present in various degrees in pipes of all grades are:
As mentioned, low-alloy steels have a total amount of alloying elements below 5%; high alloy steel has a higher percentage of these elements.
