Product Description

TP347H seamless stainless steel heat exchanger tubes offer superior strength and creep resistance at elevated temperatures, making them ideal for high-stress applications. These tubes can withstand temperatures up to approximately 1,200°F (650°C) and are specifically designed for high-temperature environments with enhanced corrosion resistance and mechanical strength.

The TP347H grade contains higher carbon content and is stabilized with niobium to prevent carbide precipitation, ensuring long-term performance in demanding applications.

Chemical Composition

Grade	Cr	Ni	Nb	C
TP347H	17.0-19.0%	9.0-13.0%	≥ 10x C content, typically 0.2-0.7%	0.04-0.10%

Mechanical Properties

Grade	Tensile Strength	Yield Strength	Elongation	Hardness
TP347H	≥ 205 MPa (30 ksi)	≥ 515 MPa (75 ksi)	≥ 35% in 50 mm	Typically ≤ 95 HRB

Key Applications

Chemical Processing: Heat exchangers and reactors for handling high-temperature and corrosive chemicals
Power Generation: Boilers and superheaters for high-temperature steam service
Petrochemical Industry: Refinery applications with high-pressure steam and corrosive substances
Aerospace Industry: Exhaust components requiring high-temperature resistance
Industrial Heating: Furnaces and kilns with severe thermal cycling requirements
