ASTM A335 Oxidation Resistance Seamless Welded Pipe Welded Steel Pipe For High Temperature

ASTM A335 P11 Seamless Welded Pipe for High-Temperature Service

1. About ASTM A335 P11 Pipe

Trade Name: 1 ¼ Chrome
Grade: P11
UNS #: K11597
Pipe: A335/SA335
Forged/Bored Pipe: A369/SA369
Chromium and molybdenum are important elements of P11. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance. It also enhances the corrosion resistance of steel and inhibits pitting.

4. Enhanced properties of A335/SA335 P11

• Toughness
• Strength
• Hardness
• Wear resistance
• Hardenability
• Hot hardness
• Corrosion resistance

Heat treating can be required to achieve some of these properties.

5. P11 Pipe Specifications

• Tensile strength, min, PSI, (MPa) – 60,000 (415)
• Yield Strength, min, (MPa) – 30,000 (205)

6. P11 Pipe Applications

Due to the ferrimagnetic characteristics of iron, a few steel alloys in A335 P11 pipes can be used in applications where their reactions to magnetism are important. This includes transformers and electric motors. P11 is also a popular grade for many different applications such as:

• Spacecraft
• Turbine blades of jet engines
• Nuclear reactors
