Product Description
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
