ASTM A335 P1 Alloy Seamless Pipes

Need an dependable alloy steel piping? ASTM A335 P1 Alloy Seamless Pipes on MetalMitra come in seamless and welded to ASTM A 335, ready for process, pressure and heat-transfer lines.

Choose seamless, ERW, welded or fabricated construction across a broad spread of diameters, wall thicknesses, schedules and lengths for process, pressure and structural lines.

Grade P1 is a carbon-molybdenum alloy steel for moderate elevated-temperature service. Controlled additions of chromium, molybdenum, nickel or vanadium give alloy steel higher strength, deeper hardenability, better toughness and stronger performance at elevated temperature.

Available forms & variants

• Seamless Pipes — The go-to choice for high-pressure and high-temperature lines.
• ERW Pipes — Economical welded pipe for utility and process piping.
• Welded / EFW Pipes — Fusion-welded construction for large-diameter runs.
• Tubes — Round, square and rectangular tubes, plus U-bends for heat exchangers.

Performance highlights

• High-Temperature Strength — Chrome-moly chemistry keeps its strength when temperatures climb.
• Creep Resistance — Proven in long-term, high-temperature pressure service.
• Hardenability — Heat-treats well to dial in strength and toughness.
• Durability — Performs reliably under heavy mechanical loads.
