JIS G3441 P9 Alloy Steel Pipe that covers “chrome-moly” seamless pipes with remarkable resistance to corrosion and good tensile strength at high-temperature service. Generally,JIS G3441 P11, P22, and P91 pipes are used in power generation and downstream oil and gas, P5 and P9 grades are for refinery applications.
Alloying elements
The addition of Molybdenum (“Moly”) increases the strength of the steel and its elastic limit, enhances 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.Alloying elements

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 and P91 are in the list, the more expensive (a P91 seamless pipe may cost approx 5€ per kg.).
