What is ASTM A335 P22 Alloy Steel Pipe?
The ASTM A335 P22 pipe specification covers "Chrome-Moly" seamless alloy steel pipes and tubes, available in grades ranging from P-1 to P-91. Fastwell offers high-quality P22 pipes and tubes with finishes such as black painting, anti-corrosion oil, and galvanized coatings based on customer requirements. Known for its tensile strength, corrosion resistance, and high-temperature performance, this alloy is cost-effective and widely used in power generation, refineries, and petrochemical applications.
The most common uses of grade P22 pipes are in the power industry and petrochemical plants. These pipes are ideal for bending, flanging, and similar forming operations, as well as for fusion welding. Chromium, a key component of stainless steel, significantly enhances oxidation resistance at high temperatures and improves tensile strength, yield, and hardness at room temperature. This makes A335 alloy steel pipes perfect for transporting fluids and gas at high temperatures and pressures in power plants, refineries, petrochemical plants, and oil field services.
ASTM A335 P22 (UNS K11522) is part of the Chrome-Moly alloy steel family, suitable for bending, flanging, forming operations, and fusion welding. The chemical composition of this material includes are :
- Carbon: 0.05-0.15%
- Manganese: 0.30-0.60%
- Phosphorus: Max 0.025%
- Sulfur: Max 0.025%
- Silicon: 0.50-1.0%
- Chromium: 1.90-2.60%
- Molybdenum: 0.87-1.13%
These elements contribute to the alloy's strength, durability, and resistance to high temperatures, making it a reliable choice for demanding industrial applications.
