Material Details – Alloy Steel P12 Seamless Pipes

Alloy Steel P12 Seamless Pipes are engineered using a low-alloy composition that provides excellent strength, thermal stability, and corrosion resistance in elevated temperature and pressure conditions. The material is ideal for high-temperature service in power generation, heat exchangers, oil & gas, and petrochemical applications.

Chemical Composition Of Alloy Steel P12 Seamless Pipes

Element Composition (%)
Carbon (C) 0.05 – 0.15
Manganese (Mn) 0.30 – 0.61
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Chromium (Cr) 0.80 – 1.25
Molybdenum (Mo) 0.44 – 0.65
This chemical makeup gives Alloy Steel P12 its unique properties of high-temperature resistance, creep strength, and good weldability, especially in critical applications.

Mechanical Properties Of Alloy Steel P12 Seamless Pipes

Property Value
Tensile Strength ≥ 415 MPa
Yield Strength (0.2% offset) ≥ 205 MPa
Elongation (%) ≥ 30%
Hardness ≤ 85 HRB (as per ASTM A335)

These mechanical characteristics make P12 seamless pipes ideal for use in pressure piping systems, boiler tubes, and superheaters where both thermal and structural integrity are essential.

Lakshya Steel ensures all material properties comply with ASTM A335 Grade P12 standards and are verified through stringent quality control and testing processes.

FAQ’s For Alloy Steel P12 Seamless Pipes

What is the material of P12 pipe?

P12 pipe is made from Chromium-Molybdenum alloy steel, classified under ASTM A335 Grade P12. It contains around 1% Cr and 0.5% Mo, offering excellent strength, heat resistance, and corrosion resistance, especially in high-temperature service applications.

What is the difference between P11 and P12 pipes?

The main difference lies in chemical composition. P11 contains higher chromium (1.25%) and molybdenum (0.5%) than P12, which has 1% Cr and 0.5% Mo. This gives P11 slightly better high-temperature strength and oxidation resistance than P12.

What is ASME P12 material?

ASME P12 material refers to ASTM A335 Grade P12 alloy steel used in seamless ferritic pipes for high-temperature service. It conforms to ASME SA335 standards and is ideal for boilers, heat exchangers, and pressure piping due to its strength and thermal resistance.

What is the steel code for seamless pipe?

The steel code for seamless pipe depends on the material and standard. For alloy steel, common codes include ASTM A335 (e.g., P12, P11), while for carbon steel it may be ASTM A106 (Grade A/B/C). Each code specifies chemical and mechanical properties for the pipe.

What grade is seamless pipe?

Seamless pipes are manufactured in various grades based on application needs. Common grades include ASTM A106 Grade B for carbon steel and ASTM A335 P12 or P11 for alloy steel. The grade determines its chemical makeup, strength, and suitability for specific services.
