Packing Ply-wooden Case With Iron Frame
Product Description

ASTM A376 specification covers seamless austenitic steel pipe designed for high-temperature central-station service, commonly used in boilers, superheaters, heat exchangers, and other demanding applications.

Chemical Composition (%) max S34709
Grade C Mn P S Si Cr Ni
TP347H 0.04-0.10 2.00 0.045 0.03 0.75 17.0-19.0 9.0-13.0

The columbium content shall be not less than eight times the carbon content and not more than 1.10%.

Mechanical Properties
Grade Tensile Strength, min Yield Strength (0.2% Offset, min)
TP347H 75ksi (515 MPa) 30ksi (205 MPa)
Key Advantages
  • Resists thermal cycling (repeated heating/cooling)
  • High creep strength at 800-1000°C (1472-1832°F)
  • Nb (Niobium) stabilization prevents carbide precipitation
  • Better sulfidation resistance than 304H/321H
  • Resists coking & carburization in hydrocarbon environments
  • Superior oxidation resistance in steam environments
  • Reduces weld decay risk (due to Nb stabilization)
  • Longer lifespan than 310S in cyclic heating
  • Longer service life (reduces downtime)
  • Better weldability than 321H (less sensitization risk)
  • Cost-effective for 600-900°C (1112-1652°F) range
High Frequency Welding Fin Tubes

High frequency welding fin tubes are specialized tubes manufactured using high-frequency electrical currents to heat and fuse metal edges without additional filler materials. Base tubes and fins are typically made from carbon steel, alloy, or stainless steel.

Advantages of HFW Finned Tubes
  • Enhanced Heat Transfer Efficiency
  • Superior Mechanical Strength & Durability
  • Cost-Effective Manufacturing
  • Design Flexibility & Customization
  • Reliable Performance in Harsh Conditions
