Product Description

Seamless Alloy Steel Pipe ASTM A355 Grade P1  

ALLOY 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 P1 ALLOY STEEL SMLS PIPE

 

ASTM A335 P1 Pipe is made up of 1% chromium, carbon, manganese, phosphorus, sulfur, silicon and molybdenum.

 

The mechanical properties of the A335 P1 Vs P11 are similar with 205MPa minimum yield strength and 415MPa minimum tensile strength. The pipes are of larger diameters. There are round, square, rectangular, hydraulic and other forms of the Sa335 Gr.p1 Pipe. The pipe ends differ in shape as beveled, plain and threaded ends. These are useful in different application contexts. The thickness of the pipes can vary from 3mm to 12mm. The ASTM A335 P1 Pipe can be formed as cold drawn, cold rolled types. The pipes can come in single random, double random and cut to length sizes.


A335 P1 Alloy Steel Pipe can also be further hardened by heat treatment. The low carbon steel provides better welding capacities in applications like petroleum, petrochemical, oil and gas and other fluid transmission lines.

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:

  • Aluminum: decreases oxygen from steelmaking
  • Boron: used to produce fine grain size and enhance steel hardness
  • Cobalt: used to enhance the steel’s heat and wear-resistance
  • Manganese: gives better steel hardenability
  • Nickel: Enhances toughness, hardenability and impact strength at low temperatures
  • Silicon: decreases oxygen, enhances hardenability and toughness
  • Titanium: prevents precipitation of chromium carbide
  • Tungsten: refines steel grain size and enhance the steel hardness, especially at high temperatures
  • Vanadium: gives steel enhanced fatigue resistance

 

As mentioned, low-alloy steels have a total amount of alloying elements below 5%; high alloy steel has a higher percentage of these elements.
