Introduction

ASME SA335 Grade P5 alloy steel pipe is a high-performance “chrome-moly” solution designed to withstand moderate pressures and temperatures. With a carefully engineered balance of chromium and molybdenum, P5 pipes are essential for boilers, refineries, and power-generation systems.

Mcneil Instrument is a leading manufacturer, supplier, and exporter of ASME SA335 P5 alloy steel pipes in India. With high-quality production processes and global certification, Mcneil caters to specialized industries worldwide.

Decoding Grade P5: Composition & Features

  • Chromium (1.90–2.60%) enhances temperature and oxidation resistance.
  • Molybdenum (0.45–0.65%) improves strength, creep resistance, and wear properties.
  • These pipes are ideal for high-temperature service, offering high tensile strength (~415 MPa) and yield strength (~205 MPa), with excellent resistance to stress and thermal degradation.

Manufacturing & Quality Assurance

  1. Raw Material Selection: Premium P5 alloy billets.
  2. Pipe Forming: Sophisticated hot-finishing processes.
  3. Heat Treatment: Normalized and tempered to meet mechanical requirements.
  4. Rigorous Testing: Chemical analysis, tensile tests, hydrostatic testing, and ultrasonic/radiographic inspection.
  5. Traceability: Mill Test Certificates (EN 10204), compliance with ASME SA335, and IBR-certified material.

ASTM A335 P5 Alloy Steel Pipe Manufacturer, Supplier & Exporter in India

Introduction

The ASTM A335 P5 alloy steel pipe, commonly known as Chrome Moly pipe, is designed for high-temperature service in industries such as power generation, petrochemicals, and refineries. Made from seamless ferritic alloy steel, it offers excellent mechanical performance under pressure and elevated temperatures.

Mcneil Instrument is a leading manufacturer, supplier, and exporter of ASTM A335 P5 alloy steel pipes in India. We are committed to delivering reliable, high-quality products that meet stringent international standards.

Unpacking ASTM A335 P5: The “Chrome Moly” Advantage

ASTM A335 P5 specifies seamless ferritic alloy-steel tubes for high-temperature service. The “Chrome Moly” name comes from its chemical composition.

  • Chromium (Cr) enhances oxidation resistance and boosts tensile strength, yield strength, and hardness at room temperature.
  • Molybdenum (Mo) improves high-temperature strength, wear resistance, and creep performance, while also inhibiting pitting corrosion.

These elements allow P5 alloy steel pipe to withstand harsh environments and mechanical stress.
