ASTM A335 P11 Boilar Steel Pipe For Power Plant
Specification
ASTM A335 P11 Alloy Steel Pipe is a seamless ferritic alloy steel pipe designed for high-temperature service, characterized by its chromium (1-1.5%) and molybdenum (0.44-0.65%) content, providing excellent high-temp strength, hardness, and resistance to creep and oxidation, making it ideal for boilers, superheaters, heat exchangers, and petrochemical plants. It's available in various sizes and thicknesses, supplied hot-finished or cold-drawn, and typically heat-treated (annealed, normalized & tempered) for optimal performance.
