ASTM A335 P9 High Temperature Alloy Steel Pipe

For over a decade, Yuhong Group has been a trusted provider of stainless steel, duplex, and nickel seamless pipes with an annual sales volume exceeding 80,000 tons. Our client base spans across 45 countries, serving industries including mining, energy, petrochemicals, chemicals, food processing, paper mills, gas, and fluid industries.

Product Overview

ASTM A335 P9 (ASME SA335 P9) seamless ferritic alloy steel pipes are engineered for high-temperature applications. With UNS designation K90941, these pipes offer exceptional performance in demanding environments.

Key Features

High corrosion resistance for extended service life
Excellent performance in extreme temperature conditions
Superior machinability and weldability characteristics
Ideal for flanging and bending applications
Multiple surface treatment options available

Applications

These pipes are essential components in boilers, chemical processing, power generation, petroleum, oil, and gas industries. Recommended for use in cokers, hydrocrackers, high-temperature and ultra-high-temperature lines, and reheat lines.

Material Properties

The inclusion of molybdenum enhances strength, elastic limit, wear resistance, impact quality, and hardenability while reducing brittleness and preventing pitting corrosion. Chromium prevents oxidation at elevated temperatures and improves corrosion resistance.

Alloying Elements Benefits

Aluminum: Reduces oxygen content during steelmaking
Boron: Achieves fine grains and increases steel hardness
Cobalt: Enhances heat and wear resistance
Manganese: Provides improved hardenability
Nickel: Enhances toughness, hardenability, and impact strength
Silicon: Reduces oxygen content and improves hardenability
Titanium: Prevents precipitation of chromium carbide
Tungsten: Refines grain size and increases hardness at high temperatures
Vanadium: Improves fatigue resistance
