Alloy Steel Pipes & Tubes GRADE P5

GRADE P 5

We offer a wide range of ASTM A335 P5/5b/5c Alloy Steel Seamless Pipes that is using high quality raw materials . These are manufactured in conformance with the international quality standards.
Also available these seamless pipes in different size, grades, thickness & Specification demanded by the clients.

These pipes are used in various application industry like petrochemical, engineering, chemical, oil and gas and other industrial etc. We also offer our clients in competitive prices in the market.

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.
