Astm A285 Alloy Steel Seamless Pipe P91 P22 6"-18" For Shipyard

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 A335 alloy steel pipes fit ASTM A234 WPx series buttweld fittings (WP5, WP9, WP91) and A182 Fx

forged fittings and flanges (A182 F5, F9, F11, F22, F91). All these materials have similar chemical and mechanical

properties and can be joined or welded.

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:

1. Aluminum: decreases oxygen from steelmaking

2. Boron: used to produce fine grain size and enhance steel hardness

3. Cobalt: used to enhance the steel’s heat and wear-resistance

4. Manganese: gives better steel hardenability

5. Nickel: Enhances toughness, hardenability and impact strength at low temperatures

6. Silicon: decreases oxygen, enhances hardenability and toughness

7. Titanium: prevents precipitation of chromium carbide

8. Tungsten: refines steel grain size and enhance the steel hardness, especially at high temperatures

9. 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.

CHEMICAL COMPOSITION

The types of alloy steel covered by the ASTM A335 – ASME SA335 specification are designed with a “P” prefix,

from P5 to P92. Grades P11/P22 and P91/92 are typically found in power stations, whereas grade P5 and P9 are

more common for application in the petrochemical industry. Grades P9, P91 are, in the list, the more expensive

(a P91 seamless pipe may cost approx 5€ per kg.).
