20X20H14C2 AISI 309 Stainless Steel Seamless Pipe For High Temperature Container
Material
20X20H14C2 (also known as AISI 309) stainless steel is a chromium-nickel alloy steel known for exceptional oxidation and corrosion resistance at elevated temperatures. Its chemical composition and microstructure make it ideal for manufacturing seamless pipes used in high-temperature containers, furnaces, and heat exchangers.
Specification
- Standard: ASTM A213 / A312, ASME SA213 / SA312
- Form: Seamless pipe
- Size Range: Generally available from 1/8 inch to 24 inches (OD)
- Wall Thickness: Schedule 5 to Schedule 160, or as per custom requirements
- Length: Usually 6 meters, 12 meters, or cut to length
- Heat Treatment: Annealed condition for enhanced ductility and toughness
Key Features
- Excellent resistance to oxidation up to 1100°C (2000°F)
- High tensile strength and good creep resistance at elevated temperatures
- Superior corrosion resistance in mildly oxidizing environments
- Good formability and weldability
- Suitable for repeated thermal cycling without degradation
- Resistant to carburization and thermal shock
